May 15, 2022: Is it Gone?

Yesterday, there was still significant ice in the Manitou, but not much anywhere else, unless there was some down in the Big Traverse.

Devon Ostir has a dock cam with a view across the Manitou towards Whisky Island, with a smaller, nameless island in the foreground. Yesterday, he sent in a picture that showed quite a lot of ice clustered around his property, and he promised to send another when the ice was gone. He made that update at around suppertime last night.

Here are a pair of pictures that show the last ice going from his location on Hare Island.

Yes, you can click on them if you want to see a larger version.

Devon Ostir’s dock cam at 6:36pm on May 14.

Naturally, I checked the weather for that time frame, and saw that the wind, which had been from the south or southwest most of the afternoon, became westerly at 5:00pm.

This ice was part of the largest remnant in the northern half of the lake. Has the wind destroyed it or merely shifted it? I hope to find out today.

If you’re out boating in the Manitou today, drop me a line if you do encounter any ice. Same goes for any of my pilot friends. Please remember that even if the ice is gone, the high water will have resulted in lots of ‘deadheads’: floating logs or timbers. Also, some rocks that used to be visible will now be lurking as submerged reefs.

We missed Satellite Saturday yesterday, so here’s how things have been developing there.

MODIS image of Lake of the Woods from Terra satellite, May 13, 2022, in false colour.

I’m fairly certain that the blue patch seen near the Northwest Angle on Friday is ice. There might be some showing on Shoal Lake, too. Cloud cover makes it hard to tell if there’s any ice in Buffalo Bay, as seen in Jared Cantor’s photos from Saturday morning.

MODIS image of Lake of the Woods from Terra satellite, May 14, 2022, in false colour.

On Saturday we only got this partial view of Lake of the Woods from Terra, and Aqua’s view was worse. There might be some ice on the south end of the lake, but at least some of that blue is probably wisps of ice cloud.

The only debate now is whether ice-out was yesterday, or will be today or tomorrow. I don’t think I’ll be able to positively confirm it for yesterday, so it will likely go on the graph as the 15th or 16th, depending on what information I receive today.

The weather:

Some cool temperatures are coming in the next week, along with some more rain. The rainfall amounts could be in the 10mm range, which would be bad, as water levels are already very high. As for the temperatures, it might drop as low as 0°C on Friday night. As we start the long weekend, grr. I suppose the garden hose will have to stay in the basement a little longer. We might see a skin of ice on puddles, but certainly not on lakes.

Early this morning, I received two photos from Jared Cantor. He took them yesterday morning from an airliner on the way from Toronto to Winnipeg. Jared was sitting on the left side of the plane, so his window seat looked south. Here’s what he saw from about 30,000 feet.

Click on these pictures to enlarge them.

Bigsby Island, Big Island and Big Traverse.

Everything’s big on this end of the lake. Above and left of centre are slender Pine Island and Sable Island,  Four Mile Bay, and the mouth of the Rainy River. The patch of ice is near Long Point.

Big Traverse, Buffalo Bay, Buffalo Point, Muskeg Bay, and Warroad, Minnesota.

In this second view from a minute or two later, the right side of the frame shows the view south across Buffalo Bay to Buffalo Point. Beyond that is Muskeg Bay and Warroad, Minnesota. The big patch of ‘land’ in the middle of the picture is actually another expanse of ice.

Thanks, Jared!

The photos above were omitted from the first version of this post. I meant to include them but lost track.

Knowing where we stood yesterday, I was very eager to go flying today. I knew there couldn’t be much ice left. I wanted to see what there was, to get the best idea of when the last of it will be gone.

So I called my old friends at MAG Canada to see if I could book a short flight. They wouldn’t take my money. They insisted on giving me a free flight for old time’s sake. I always knew that the company supported me and Ice Patrol on a local level, but I was touched to hear that this was supported by the head office. Thanks, Mark!

So I met up with Andy Zabloski at the hangar, and we went for a short tour. I wanted to head down towards Sioux Narrows, because I haven’t had any pictures from that direction recently.

You can click on these pictures to see a larger version.

Bigstone Bay. Sultana Island and Quarry Island are in the middle of the picture.

The first thing we noticed was that there was no ice at all left in Bigstone Bay. Sometimes Heenan Point or Needle point will trap some late ice, but not today. All the bays in this area are completely ice-free.

We had set off to look at Andrew Bay, Witch Bay and so on, but we couldn’t find any ice in that region at all, so we turned towards areas more likely to have late ice.

The first ice we did see was in the Manitou.

The Manitou. Bare Point in the foreground, Town Island in the middle.

There is ice here, but not very much. It’s hugging the shore of Wolf Island and Hare Island.

Here’s what it looks like from Devon Ostir’s dock cam on Hare Island.

He’s promised to send me an update when his shore is clear of ice. Thanks, Devon!

Now back to our flight. There’s usually late ice south of the Barrier Islands, but we didn’t see anything obvious, so we went further south to see if we could spot any at the south end of the lake.

Cliff Island and the Alneau Peninsula. Little Traverse is in the distance.

It was a long way away, and the patchy light from a broken cloud layer makes it hard to be certain, but I think there’s some ice down by Bay Island, in the Little Traverse.

Next we turned north to take a closer look at the Barrier Islands.

The Barrier Islands.

We had missed it at first glance, because it’s not a big sheet, but there’s some ice against the south shore of Shammis Island, very near the centre of this picture. Zoom in to see it, and the larger area of ice in the Manitou that we saw before.

The Manitou also has another ice remnant around Wolf Island.

Wolf Island, Welcome Channel, Thompson Island, Holmstrom’s Marsh.

There’s still some soft pan ice drifting in this area. In this picture, it’s right by the propeller blade, near Houghs Island, but it’s probably on the move.

We got a nice shot of the Scotty Island to Hay Island area.

Scotty Island, Middle Island, The Hades and Hay Island.

We found no ice at all in this area, and that also includes Slate Island, Railway Island, Queer Island and Square Island.

That concluded our look at the ice on Lake of the Woods. In short, we found almost none. If it’s not gone tonight, it certainly will be by Monday morning.

Here’s a picture from Kelly Belair, showing what some of the ice looks like when it piles up on a reef. This was taken near Rocky Point at about mid-day today. He says the picture doesn’t do it justice.

Ice pile by Rocky Point.

By the way, ice remnants are not the only boating hazard right now. Because of the high water levels, there are lots of deadheads and debris in the water. Parts from damaged docks and cribs have been reported.

All marinas should be operable now, but they’ll have a lot of catching up to do.

One last picture from our flight. As we were circling to return to the airport, we flew over Upper Black Sturgeon Lake. Water levels are up there, because the Winnipeg River is so high that it’s flowing into the Black Sturgeon Lakes, instead of the other way around. This was apparently an overstatement. River levels are high enough that the Black Sturgeon Lakes are not draining normally, but I heard recently that the rollers are still above water, so the river is not actually higher than the lakes. At least, not yet.

Beauty Bay Golf Course.

As just one example of how bad it is, the water is lapping at the clubhouse of the Beauty Bay Golf Course. The front parking lot and dock area (near the middle of this picture) are submerged.

So a special thanks to Andy and my old colleagues at MAG for this farewell flight. I got to ride one more time in GTWW, a plane I flew for thirty-two years and (checks logbook) over 5000 hours. Sad sniff.

Signs of spring:

My dog found a bee today.

Motorhomes and campers. Boat Trailers. Generally heavy traffic. Potholes with a capital P.

Ice Patrol will be wrapping up for the year soon. We’ll try to establish the actual date the ice was all gone, and we’ll update the graphs accordingly. I’m still hoping for a nice satellite image of an ice-free lake to round things off.

If you found Ice Patrol valuable this year, let me just mention that I did insert a donations form back in March. It uses the services of Stripe, and works in US dollars. Traffic is way up since March, so here’s a link to it, in case you missed it, and feel like it. The form is at the bottom of this post from March 16. Every donation is appreciated, but there’s no obligation. It’s entirely up to you.

 

May 13, 2022: Forecast Friday

Soon, the ice-out date will be history, and not a matter for forecasts.

But while we still have a little ice left, here’s Sean’s last take on it for this year.

Remember, you can click on this graph to see it large and sharp.

Lake of the Woods Thaw Forecast.

This year’s temperature profile (the blue line) runs parallel to the best case example from 2007 (the red line). Since last week, Sean has updated the path of the blue line to replace forecast temperatures with actual ones up to the present.

His conclusion? Based on temperatures, the lake should be entirely ice-free in the evening of May 17th.

Temperatures are not the only factor in play, though, so there’s still some wiggle room for wind and high humidity to get rid of the ice even faster. Certainly it is very windy today. I think it’s possible that the ice might be gone a day or so earlier than the temperatures suggest.

In the meantime, although there is still ice present, many people will be able to reach their cottages by boat already. For those who cannot, yet, it is only a matter of days.

Satellite imagery is a bit of a tease lately, because of cloud. Yesterday, Terra satellite was able to see only the south west corner of the lake. Today, Aqua got a look at only the east side. In both cases, there was no significant ice visible, but we’re reaching the stage where it would be hard to spot from space.

Lake levels continue to rise. Water is flowing into Lake of the Woods faster than it can be let out. Sean calculates that the surplus amounts to an olympic-sized swimming pool’s worth of water every second and a half. That would raise the lake by an inch and a quarter every day. If that continued for a week, it would come to another fifteen inches, but nobody knows exactly how long the inflow will remain so high.

As mentioned on Ice Patrol yesterday, the water level of the Winnipeg River is so high that it’s raising the water level in and around the Black Sturgeon Lakes. That’s washed out a number of roads, and resulted in an evacuation order for a lot of people that live north of the Kenora Bypass. The evacuees will have a narrow window to get out. The City of Kenora Works Department is attempting to re-open one route with heavy equipment, and they think they can keep that road passable for four hours this afternoon. After that, the floodwaters will close off all the ways out.

You can read more–and see a map of the affected area–at Kenora Online.

 

 

 

May 12, 2022: It’s All Going

I wasn’t expecting pictures today because of the heavy rainfall warning. But the weather has been better than expected so far, and I received three great sets.

Before we start with the pictures, the comments form is overflowing with people reporting that various places are open, or opening fast.

Let’s back those assertions up with some evidence. First up, aerial photos from James Hendy at River Air. He’s another of my former colleagues from decades ago.

You can click on these pictures to see larger versions that reveal more detail.

James started at Poplar Bay.

Poplar Bay.

It’s partly open, but there’s ice at the south end. Let’s take a closer look.

Poplar Bay, Welcome Channel, Wolf Island, Hare Island.

Next, James cruised out to the Manitou. The first view looks roughly south.

 

The Manitou. Whisky Island at the right, Barrier Islands in the distance.

Still ice here, and the ice roads haven’t broken apart yet. The Manitou is one of the last places to let go, but once things reach this stage of soft ice, it’s very vulnerable to wind.

Looking more to the south west shows the western stretch of the Manitou.

West Manitou. Crow Rock Island at the upper centre.

Then back towards Kenora. The ability to reach Scotty Island is a key milestone in boat access.

 

Scotty Island in the distance.

I’ve heard from BB Camps that Town Island is accessible, and it looks like you can make it to Scotty Island now. More about the beach there, later.

Thanks, James!

Our second set of photos come from contributor Scott Benson.

Over Sugar Bay looking east down Clearwater Bay. It’s open water west of here. Frozen east and south.

Scotty’s beach in foreground looking east over Bigstone Bay.

That beach is looking pretty waterlogged. I like the little cluster of ice-road fragments, though.

Looking north over Shammis Island where the main ice road crosses. This area of the lake is 90+% ice at this point.

I’ve said it before, but the ice roads are the last things to let go. This broken one shows how close we are to total ice-out.

Over Ash Bay looking east at the grouping of islands including S Island and north up Corkscrew Channel. Open around S island and frozen to the east towards Whiskey island.

There’s still quite a lot of ice out there, but it’s almost all candled. Basically it’s just fancy ice cubes (well, hexagons, actually) floating around and keeping each other company.

Just west of Victoria Island looking north at Mud Portage, and Woodchuck/Deception bays in the distance. Woodchuck and Deception are ice free.

Over the entrance to Echo bay looking east down Ptarmigan Bay, Zig Zag island in the center. Ice free north of Zig Zag island.

Looking south east at Echo Bay. About 1/2 open water.

West Hawk Lake. This ice has been pushed around by the wind for the past 3 days and won’t last long.

I have had at least one report that West Hawk Lake is wide open. Consider that if an observer was standing on the far shore, they would not be able to see this ice remnant on the west side.

Looking south over Shoal Lake. Some areas open (maybe 5-10%) ice in the middle looks white, the strongest ice I spotted today.

Oh, good. I just had someone asking about Shoal Lake. Typically, Shoal Lake’s ice lasts a few days longer than it does on Lake of the Woods. There’s a pretty big pan there, but I don’t think it will last through the weekend.

Scott was kind enough to write captions for his pictures, saving me a lot of work. Thanks, Scott!

But wait, there’s more.

Here’s a picture  of the ice at Clearwater Bay from Brendon Thiessen that came in while I was writing this post.

This was taken at 2pm today (12/05/2022). Looking Northwest from Big Duck Island toward Sugar Bay.

Brendon was using a drone to check on his docks, (they’re fine) and sent me this to show the ice. Thanks, Brendon!

I’ll finish with a set of aerial photos from MAG Canada’s Justin Martin.

We’ll start with Northern Harbour, because I’ve been curious about it for a  couple of days.

Pine Portage Bay, Sultana Island and Bald Indian Bay.

There’s water around the docks now, but before you phone Northern Harbour, take note that there’s not actually a clear route out of Pine Portage Bay yet.

From Bare Point, Looking west towards Treaty Island.

It looks as if you could take a boat out through Devil’s Gap now. There’s still a lot of pan ice, though, so you’d want to be careful not to get trapped.

Middle Island and Scotty Island.

The same applies if you try to go beyond Scotty Island. Large pans of ice, moving around because of wind and current. South of the Barrier Islands, those sheets are massive. We’ll take a closer look in a minute.

But first, Corkscrew Island, Ptarmigan Bay and Clearwater Bay.

 

Corkscrew Island, looking west towards Zigzag Island.

Now the Barrier Islands, and the huge ice sheet south of them.

East Allie Island and Allie Island, looking over those Barrier Islands at the ice to the south.

Most years, that ice covered area is the last to go. Small pans of this may survive for several more days.

Thanks for these, Justin!

This last shot from Justin is a little different.

Judging by the Kenora Airport in the background, this is the Essex Road. As you can see, a lengthy stretch of it is underwater.

This is not the only road in the region to be flooded or washed out. The problem in this location is that the Winnipeg River is now higher than the Black Sturgeon Lakes, causing their water levels to rise.

It’s raining as I write this, and we have another heavy rainfall warning, so water levels in the whole drainage basin of Lake of the Woods are sure to continue rising.

As far as the ice is concerned, it’s melting everywhere, and it’s melting fast. It won’t be long now.

 

 

May 11, 2022: Turning Point

With half the ice gone, I stop showing where the water is expanding, and start looking at where the ice is shrinking.

Technical notes:

I have added a link to the Navionics online map of Lake of the Woods to the right-hand sidebar, next door to the Satellite links. If you don’t recognize some of the place names I use, this zoomable map is a great help. When I’m writing Ice Patrol posts, I keep it open on a separate tab in case I need to check something. This is way easier than unfolding and refolding my many marine charts.

Ice Patrol is having some of its heaviest traffic ever. Recently, it’s been averaging over 2000 visits a day. Notably, there is a higher than normal proportion of visitors from the USA. I think they’ve missed us. Come on up!

I received more pictures yesterday than I could process. Here are Josh Broten’s lovely pictures from the south side of the lake.

You can click on these images to see a larger, zoomable version.

Looking SE over Buffalo Point. The ice is gone from Warroad to Buffalo and then narrows as you get to Rocky Point.

Over Buffalo Point looking NW. You can see Moose Lake is ice free.

Over Sand Point Bay looking SE. you can see of in the distance how the the lake is ice free from Rocky Point to Rainy River.

Looking NE over the NW Angle. Mostly open water from Oak Island and north.

Over Windigo Island looking NE. For the most part it is open water all the way past Tranquil Channel and Big Narrows.

Looking westward you can see Shoal Lake is still iced over.

Over Royal Island looking NE toward Kenora. Tranquil channel and Big Narrows are in the center of the picture.

Over Tranquil channel looking east over Sunset Channel.

Over Crescent Island looking north towards Kenora.

Over Yellow Girl Point looking Northerly towards Kenora. Lots of of Ice still between Kenora and the Alneau.

Another look to the west over sunset channel.

Looking east over Smith Island with Sioux Narrows in the distance. Lots of open water.

Josh is one of my favourite contributors. He edits his own pictures and even provides captions. Thanks, Josh!

Between Tom Hutton’s coverage of the east and north parts of the lake shown in yesterday’s post, and Josh Broten’s flight over the south and central parts, we’ve checked almost everything except the Ptarmigan and Clearwater Bays in the north west corner and Morson in the south east.

It looks as if we are now on track to have one of the fastest (and latest) thaws of this century. Once half the ice has melted, the remainder is floating loose at the mercy of the wind. With mid-May temperatures, it should be only a matter of days until it’s all gone. I looked back at 2014 to search for pictures showing an equivalent amount of ice cover at the same time of year, and I think we’re just five to seven days from total ice-out. A quick check of the MODIS archives from that similarly late spring suggests the same sort of timeline.

If this does become the fastest thaw in my records, there will be two main reasons. First, when the thaw starts late, it’s likely to run into warmer temperatures in late spring. So late starting thaws generally run faster than the ones that begin in March. Secondly, we’ve had an extraordinary amount of wet weather. A string of Colorado lows set records for precipitation in April and I think early May, too. And while you might be tempted to credit the rain for the rapid melt, meteorologists insist that it’s actually the high humidity that does the heavy lifting.

Signs of spring:

The floatplanes have been flocking in. River Air’s Caravan has been joined by a turbine Otter and a Beaver.

On a recent drive from the Kenora waterfront to Keewatin, I spotted another small plane near Q-104, meaning that I saw more  floatplanes in the water than boats. Most of the marinas had no boats at all at the docks, or just one or two. I expect that to change rapidly, as I have noticed a lot of boat trailers in the last few days, and the ice is letting go at many of the docks.

If you’re planning to put your boat in the water soon, don’t forget your safety equipment. Water traffic will be light at first, so if you have motor trouble you might have to wait a while for help. It is wise to take warm clothing with you.

Time for my annual reminder that when float planes are landing or taking off, they have the right of way over boats, because those stages of flight are critical. Safety Bay is a designated water aerodrome, so be alert there. Once a plane is on the water, it becomes a boat in the eyes of the law, and has the same right-of-way as other boat traffic. Having said that, floatplanes have no brakes and limited steering*, so I suggest giving them a wide berth.

*If you want to know how good a floatplane pilot is, you don’t watch them land. You watch them dock!

 

 

May 10, 2022: It’s Going Fast

Yesterday, Ice Patrol and I took a day off, as poor weather meant I had no pictures to share. I felt a warm spell and then wind and wet weather should have made a big difference, but I had no way to see how much, and I didn’t want to speculate.

But today the sun came out, and we got some answers. Both Aqua and Terra satellites got good shots with their MODIS equipment today.

MODIS image of Lake of the Woods from Aqua satellite, May 10, 2022, in false colour.

There are big changes visible in the few hours between Aqua’s pass and Terra‘s.

MODIS image of Lake of the Woods from Terra satellite, May 10, 2022, in false colour.

It looks as if the lake has lost about half of its ice. Normally, I’d say things should go fast from this point, but they already are!

The nice weather brought out the pilots, too, and I received a lot of pictures today. Tom Hutton had a chance to take a great series of pictures of the east side of the lake as he flew from Fort Frances to Kenora in sunny (but very bumpy) conditions.

You can click on Tom’s pictures to see larger, zoomable versions with more detail.

Nestor Falls.

Tom’s route brought him to Lake of the Woods at roughly Nestor Falls. Lots of water here now.

Then Whitefish Bay, which we seldom get pictures of.

Whitefish Bay.

In this shot, it looks like Whitefish Bay has entirely melted. But we need to take a closer look at the northern part of the bay.

Northern part of Whitefish Bay. Sioux Narrows is visible at the right, below the propeller blade tip.

Turns out there’s still extensive ice on the north half of Whitefish.

Whitefish Narrows.

Whitefish Narrows is just below the blade tip. These narrows are actually early to thaw, but this year it has taken some time for that open water to spread into Whitefish Bay.

West end of Long Bay and Yellow Girl Bay.

Still ice in Yellow Girl Bay. And plenty more to the north west.

The Barrier Islands and the Eastern Peninsula.

This shows almost the full stretch of the Barrier Islands. The Elbow is at the left, and French Narrows are near the middle. Lots of ice south of the Barrier Islands, which is typical. The distant ice is the Manitou.

West Manitou.

In the picture above, Birch Island is above the centre, and part of Whisky Island is at the right edge. Almost all ice here, as this is another late-thawing area.

 

East Manitou.

We’re getting closer to Kenora now. The curved beach at Scotty Island is just at the right edge of the frame.

Wildcat Island and Anchor Island.

Wildcat is in the centre. The foreground ice touches Hough Island and sticks to the shore of Thompson Island at the left. Holmstrom’s Marsh still looks icy.

Treaty Island.

Treaty Island dominates this picture, with Shragge’s Island just by the propeller spinner.* Notice how the ice roads are holding on between Treaty Island and Rogers Island, just above the engine nacelle.** Further left, by the tip of the propeller blade, the ice roads around Gun Club Island in Rat Portage Bay are breaking up and moving around. That’s significant, because Gun Club Island is usually late to break free.

*The shiny cover at the centre of the propeller is called the spinner. It’s like a hubcap, but very firmly attached.

**The streamlined fairings that cover the engines on a twin-engined airplane are the nacelles. On this King Air, the nacelles are painted white.

I wanted to see Pine Portage Bay, because Barb Enders sent me two pictures of Northern Harbour on the weekend. The first was taken just before noon on Friday. The second was taken on Sunday morning, just 46 hours later, and there was a spectacular change in the condition of the ice.

Pine Portage Bay.

Looks like the ice is still holding on there. At the right of the photo, you can see that Bigstone Bay is still ice-covered, too. Slow currents mean that Bigstone usually lags behind.

Our last shot from Tom shows the downtown Kenora waterfront and part of Coney Island. Thanks, Tom!

Coney Island.

There are still sizeable pans of ice south of Coney, around Goat Island and Johnson Island in Rat Portage Bay. Most years, once those were gone, the Coney Island footbridge would be removed to facilitate boat traffic. But not this year.

The Coney Island footbridge was damaged by wind and ice on Monday evening. You can read about it on Kenora Online.

So that’s one sign of spring we’ll have to do without this year, but there are others.

The first floatplane docked on the Kenora harbourfront today. River Air’s Caravan will be followed by more of their planes tomorrow. The pilots who brought it down from Minaki, Jamie Clemmens and Robyn Warken, took some pictures for me, but there were technical issues, and I’m still working on that.

Josh Broten took some pictures today, too, and they’ll round out the lake coverage with photos of the south west portion. It’s getting late, so I’ll put them up tomorrow morning.

Thanks everyone!

The weather outlook for the next while is a mixed bag, with more cloud and some showers. Temperatures will be mostly back to near normal, but with cooler conditions as the weekend arrives, naturally. Things should recover a bit a few days later.

May 8, 2022: Satellite Sunday?

Not really. These pictures are from Saturday the 7th, but they missed the deadline for getting posted yesterday.

The good news is, we got a solid pass from Sentinel 2 yesterday. This ESA satellite has a narrow field of view, so it doesn’t often image all of Lake of the Woods*. But when it does, the resolution is a dream.

*For broad coverage, the MODIS cameras on NASA’s Aqua and Terra satellites are better, and they pass overhead every day. But their images of Lake of the Woods are small, and cannot be enlarged.

MODIS image of Lake of the Woods from Terra satellite, May 7, 2022, in false colour.

This is a MODIS image from yesterday. The cloud cover is different from the pictures below because Terra and Sentinel 2 made their passes some hours apart.

 

Let’s start with Sentinel 2‘s view of the whole lake, in Short-wave Infrared. You can enlarge this image by clicking on it to see it full screen.

Sentinel 2 image of Lake of the Woods in Short-wave Infrared, May 7, 2022.

I don’t know if the SWIR version of a Sentinel 2 image is directly comparable to a MODIS false-colour image, but it’s very similar.

It’s very clear that ice quality is now deteriorating fast all over Lake of the Woods.

There was cloud in the northern parts of the lake yesterday, spoiling Sentinel 2’s view, so let’s take the opportunity to take a closer look at the south half of the lake, which I seldom get good images of. [It’s too much of a detour for a Kenora-based flight.] Shots of Morson and Sabaskong Bay are regrettably rare.

You can click on the following images to see them full-screen and zoomable.

Southern portion of Lake of the Woods, at higher magnification.

This is from the same image, but zoomed in even more. Click on it and enlarge it all the way to see a lot of detail. I had to cut it off just north of Big Narrows to keep the file size below the 3GB limit set by WordPress. Even then, it took me two tries to upload it to their server.

As I was preparing this post, Terry and Mary James used the comment box to ask about whether their interpretation of what the MODIS images showed at Roughrock Lake was correct.

So l’m going to show them (and you) what Sentinel 2 can really do! Note the scale at the bottom right corner. 1km is about as tight as it will go. You can try to enlarge it further, but the image gets fuzzier.

Roughrock Lake, Big Sand Lake, Little Sand Lake.

Also, this timely comment from Bargeman, via email:

I live in Minaki and have had a boat in for the last week. My wife and I broke up the last bit of ice in the middle of Little Sand Lake to Rough Rock Narrows on Thursday. So the river is open from dam to dam. This has been the quickest opening (from looking very dubious about ice being gone by May long) I can remember. The water rising creating cracks everywhere around the shorelines combined with the strong current has increased open water way quicker….thank goodness. We have Sand Lake Outpost on Big Sand Lake at it is looking like our long weekend guests will be able to stay at our place on Deadman’s Island, just north of Harbour Island.

Hope this answers your question, Terry!

So while I’m at it, let’s see if I can find something for Pete Giroux. He has a place on the Manitou Stretch, east of Lake of the Woods.

East of Sioux Narrows and Highway 71.

I think you’re in luck, Pete: this is right at the eastern edge of Sentinel 2’s latest swath.

I was also curious to see how things were looking further north, up by Red Lake and Trout Lake, but that area was covered with cloud.

Recent warm–and now moist–weather are moving things along very quickly. I tried take a look back at 2014, which was the last time we had such a late thaw. MODIS images are not available for May 6 through 9 because of cloud. The May 5 image shows only a little of the lake, and the May 10 image is blurry, but I think I can say we’re pulling ahead of spring 2014.

Aerial photos I took at around these dates in 2014 were shot in rainy weather, and are hard to make out, but I think they also show we’re doing better.

That would be good, because the lake wasn’t entirely clear until May 21 that year.

I’m confident we’re on track to keep up with Sean’s recent prediction of May 18, and since the weather has been warmer than the forecast he was working with, he may be able revise his graphs again next week.

Keep in mind that when we talk about ice-out on Lake of the Woods Ice Patrol, we mean the whole lake, entirely free of ice. Significant areas are opening to boat traffic every day, and things will be improving daily. One of the bottlenecks we face right now is a lack of  Marina access. Northern Harbour is situated on deep water, and is still iced in. Two Bears Marina, in Keewatin, has soft ice all around their docks and were not operating yet when I stopped by yesterday. Devil’s Gap Marina might have enough water to launch boats, but their open water doesn’t reach very far yet.

I haven’t surveyed a full list of marinas, but if you’re a marina operator, and you have news, feel free to use the comments form on the ABOUT page to let us know how things are shaping up for you. Are you launching yet, or opening soon?

Do you have friends who would want to follow Ice Patrol? I often get emails from people asking to get on the list. THERE IS NO LIST! To follow Ice Patrol and get the emails, visit the Ice Patrol home page and look for the FOLLOW button at the right side. Click it, and you’ll get an email every time I post a new article. If you change your mind, visit again and simply UNFOLLOW.

However, those emails do not tell the whole story. For one thing, if I update a post, a new email does not go out. If you want more, including updates, comments, links, access to archives and satellite images, and an FAQ page that is helpful to new users, visit the actual website.

May 7, 2022: Satellite Saturday

We’ve had almost a whole week of sunny weather, so at least one of the NASA satellites got a picture for five days running.

I was hoping to put them together as an animated gif or a slide show, but it didn’t work well.

I’ll just show them in reverse order so you can compare.

If you need help getting oriented, go to the last one, May 3, and click on it. You’ll see a version with some landmarks labelled.

The amount of progress in five days is impressive. The amount of open water is very different in the first and last pictures. But it’s the steady change in the colour (and strength) of the ice that is most important.

While we’re looking at things from overhead, Tom Lindstrom went cruising by in an airliner today and took a series of pictures from the cockpit. Many of them turned out kind of dark; I think his camera was dazzled by the brightness of the ice. I’ve enhanced the contrast on these two to improve the difference between islands and water, so they look a little odd, and the ice colour is not correct.

You can click on these pictures to see a larger version. Then zoom in, because these pictures are big

Kenora waters.

This picture covers everything from Kenora a the top left, to Second Channel at the bottom right. Zoom in and you can see the last patch of candled ice in Kenora Bay.

From Safety Bay to Bigstone Bay.

This second shot includes a wider area. Bigstone Bay is at the top right, Middle Island and Scotty Island are near the corner, Welcome Channel and Poplar Bay are halfway down the right side, and White Partridge is at the bottom.

The weather:

We hit at least 20°C yesterday, and it’s 22°C as I write this, exceeding both the forecast highs and seasonal averages. But just so you know, the record high for this date is 31.7°, set in 1953!

Now we’re supposed to get a couple of days of rain. Because weekend. But wet weather is not entirely bad. High humidity can have a powerful melting effect on ice. This is due to the energy released when water vapour condenses onto ice or snow. The humidity actually does more damage than the rain.

However, the rainy weather means we won’t get any satellite coverage until Tuesday, and it may not be good enough for my pilot friends to take pictures, either. So we’ll have a bit of an information blackout for a few days. If you go boating, you could use the comments form on the ABOUT page to let us know how you made out, and how far you got.

Signs of Spring:

I finally found time to put my summer tires on today.

Flies are out. Midges will be next, I think, and a friend mentioned that with all this standing water, the mosquitoes may get off to a roaring start this year.

I can’t find a bulletin on a planned date for the removal of the Coney Island pedestrian bridge yet. It gets scheduled for removal when the ice clears out between Kenora and Devil’s Gap, leaving the bridge as the only obstacle to boat traffic. That hasn’t happened yet.

 

May 6, 2022: Fresh Aerials

Justin Martin, my former Chief Pilot, was flying again today and had time to snap a few quick shots.

So here’s the speed tour. You can click on these pictures to see them enlarged.

Looking west over Laurenson’s Lake.

Note that Laurenson’s Lake is still frozen. There is actually a little water at the east end, off the bottom of the picture.

Devil’s Gap and Treaty Island.

Ice is yielding at both the inlet (left) and outlet (right) sides of Devil’s gap now. Open water is spreading into Rat Portage Bay, although Gun Club Island, as usual, is staying iced in a bit longer.

The plane swung left a little to show the Manitou better.

Town Island and the Manitou.

Following Keewatin Channel out to the Manitou is one of the main ways to reach open water from Kenora, and it opens earlier than Devil’s Gap. I think next week Scotty Island will be reachable by boat.

Big Narrows and Wiley Point.

Open water continues to expand all around Big Narrows. Looks like Wiley Point is getting its toes wet now.

The Barrier Islands, seen from the south side.

Justin took several pictures of the Barrier Islands area around the Elbow. I like this one best because you can see how the water is reaching north towards Middle Island and (eventually) town. The big patch of water at the left is the Elbow, and if you zoom in you can see that things are improving at French Narrows on the right.

Now that the ice is turning grey, the pressure ridges really stand out.

Thanks Justin!

Another sunny day, another MODIS shot. I think Aqua got better light quality than Terra today.

Open water continues to expand, and ice is softening all over the lake. It looks as if shorelines may be letting go, especially in the south half of the lake.

Signs of Spring:

On Kenora Bay, the ice is completely candled now. It will be gone very soon.

Motorcycles. I saw three today, and just heard another. Remember, riders need to avoid both potholes and patches of loose sand. Give them room in case they have to brake or evade.

Ticks. Found my first tick today, on my belly after walking Ebony. Yay.

Ebony gets refreshed after overheating.

No ticks on her, though, we checked. This is important because of Lyme Disease, which took the life of Piper, our previous dog. There’s a now a new option in tick preventative pills. Ask your vet.

May 5, 2022: Overview

So far this week, we’ve been looking at the lake one patch at a time. This morning, Jonathan O’Connor was aboard Air Canada’s flight AC259 from Toronto to Winnipeg. He sent in some photos.

Yes, you can click on these to see a larger version that you can zoom in on.

We’ll go from east to west, like Jonathan’s flight.

Whitefish Bay and Long Bay.

This is Whitefish Bay, and at the right of the photo is Highway 71. Don’t be fooled by the powerline, which is straighter and more obvious. The road is closer to the right edge, and much wigglier. Zoom in and you can see the open water at the  Sioux Narrows bridge. Because the camera is pointed down for this shot, it provides a good look at the condition of the ice, which looks soft.

Here’s his view of the northern part of Lake of the Woods.

North of the Alneau Peninsula.

In the foreground is the Alneau Peninsula. The Barrier Islands stretch across the middle of the frame, and if you look closely, you can see the big patch of open water at the Elbow. Above the middle to the right are Hay Island, Bigstone Bay and Longbow Lake. Towards the upper left, the water in Keewatin Channel is hard to distinguish from the land unless you zoom in. From high altitudes, the haze tends to make trees and water look a similar shade of blue, especially in the distance.

Big Narrows.

As the plane travelled west, Jonathan captured this view of Big Narrows that also shows Ptarmigan in the distance.

Thanks, Jonathan!

The continuing clear weather means there are new satellite images every day. I’ll put together a look at the whole week on Satellite Saturday, but in the meantime, here’s today’s shot from Terra.

We also have a new drone Panorama from Paul Leischow.

As usual, clicking on the still image below will take you to a panorama that you can watch, or use your mouse to interact with.

Drone view of Keewatin Channel.

It’s worth mentioning that at this time of year, this whole area would usually be all open water, with lots of boat traffic.

Thanks, Paul!

Two things are happening on Friday: Sean will reveal how the actual weather and the changes to the weather forecast affect his graphs predicting the likely timing of ice-out.

I’ll be live on Q-104 with Ken O’Neil at 7:50am to talk about that, and how the sudden arrival of spring weather is changing things.
