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.

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.

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.

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?

May 6, 2019: Photopalooza

I have a whole stack of photos today from multiple sources, so I’m going to post them with minimal commentary.

You can click on any of today’s pictures to see a full-screen, zoomable version.

First, since cloud has made it difficult to track what’s going on in the north part of Lake of the Woods lately, a pair of photographs taken from a passing Air Canada flight by Karen Boucha.

Karen says: The first shot shows north from Wiley Point.

The Alneau Peninsula is in the foreground, then huge Cliff Island, then a massive expanse of ice all the way north to the Barrier Islands. Just above the centre is the open water pushing through the Barrier Islands at The Elbow (and to a lesser extent, at French Narrows) I have more detailed shots coming up later, but the main take-away from this picture is there’s still lots of ice in the north part of Lake of the Woods.

Karen’s other photo looks almost straight down at an area south of Big Narrows.

Karen says: Open water south of Wiley Point to Outer and Portage bays and the south west end of Tranquil Channel.

Much less ice in this area.

Next I have a batch of pictures from my MAG Canada co-worker Tom Hutton. He flew past Minaki on his way to Kenora this afternoon.

Looking west at Big Sand Lake. Still frozen shore to shore, but ice looks rotten.

Little Sand Lake. Mostly open water with some large ice floes.

Gun Lake and  Minaki. Almost ice free with shrinking ice floes.

Looking south over Keewatin at Safety Bay and Keewatin Channel. Open water here.

Next are a batch of my photos. I came home via Dryden today, so I grabbed a shot over there.

This is a wide angle shot looking south at Wabigoon Lake. In the foreground, Rice Lake, north of the airport, is open. Ghost Lake and Thunder Lake, at the left, are frozen. Wabigoon is almost all white ice, but there’s open water at the west, near Downtown Dryden.

This is Vermillion Bay. Some ice near the Trans-Canada highway, and there’s more further south on Eagle Lake, but there’s a lot of open water, too.

Now on to Lake of the Woods. Photos first, with commentary for each beneath.

This is down towards Sioux Narrows, looking west. Whitefish Narrows is at the left, it’s open. Long Bay is open at the west and opening in the east, (not shown) but still has ice in between. Near the centre of the picture is Yellow Girl Bay. It’s icy, as is the big stretch of lake between the Alneau and the Barrier Islands, as seen in Karen’s first high-altitude shot.

This shot looks west along the Eastern Peninsula. Distinctive Bottle Bay is just left of centre. In the lower right, Witch Bay is open. Above that, Andrew Bay is still ice.

Let’s proceed west for a look at the water pouring through French Narrows and The Elbow that now reaches almost all the way to Middle Island. In the right foreground, that ice on Andrew Bay, but above that, Pipestone Bay is open. On the other side of Hay Island, Bigstone Bay is covered in ice, but I hear it’s weakening.

Closer look at Scotty Island, Middle Island (near centre) and The Hades. Railroad Island in the right foreground. I believe you could travel by boat from Kenora and make landfall on Scotty Island now, but not at the beach: that bay’s full of loose ice.

Here’s a close-up of Scotty Island to show what I mean.

A glance west at the Manitou and Whisky Island. Almost all ice here, but it’s breaking up.

Towards town now. This is Keewatin Channel, looking north east towards Rat Portage Bay. Still a little ice between Gun Club Island and Coney Island, but other than that, the downtown area is clear. Keewatin is in the distance at the left, Kenora at the right.

My last shot looks east over the Treaty Island area. Shragge’s Island in the foreground, Devil’s Gap in the distance, Rogers Island in between, where the ice road is keeping the ice together for now.

Josh Broten sent another picture from the American side of the lake this evening.

Josh says: This is just south of Garden Island looking north. You can see ice pretty much filling Little Traverse. Off in the distance you can also see a lot of ice still filling up the lake north of the Alneau.

It’s getting late and I have to fly tomorrow, so I’ll post this and get to bed. Good night.

 

 

May 5, 2019: Kevin Walsten

I’ve been trying to put together an update for the Minaki area for over a week now, but my flights north all seemed to detour east first.

Kevin Walsten went out in his Super Cub today, and sent me these pictures.

Kevin says: Picture taken May 5 Gunn Lake looking north at Little Sand and Big Sand lakes.

Digital cameras do weird things with propeller blades. Minaki can be seen between these two.

On his southbound return leg, he took this shot.

Kevin says: Looking south east at Big Sand and a bit of Rough Rock Lake.

Still some shore to shore ice in this area. Thanks, Kevin.

Cloudy weather continues to impede the satellites. Terra got a better look than Aqua today, but you can still only see the south end of the lake.

I’ve used the same selection frame of 800×800 pixels as usual, but all that’s visible are Muskeg Bay at the bottom left, and the mouth of the Rainy River to the right of that. As seen in Josh’s photos yesterday, there’s big change happening on that part of the lake.

Is the rest of Lake of the Woods melting as fast? I’m not sure: Big Traverse is very susceptible to windy conditions, but the more northerly parts of the lake are full of islands. There’s still wind movement, but not on the same scale. Also, if the satellite images are anything to go by, we’ve been having a lot less sunshine in the north.

Signs of spring: I saw my first loon today, on Rabbit Lake. No ice anywhere on Rabbit, by the way, not even a handful.  Some float planes are out: Kevin’s for one. Our Lilac hedge is starting to bud, so trees should finally start to turn green.

In the meantime, though, the weather will remain cold for another day before temperatures reluctantly creep up to the low double digits on Tuesday. A normal high this time of year is about 15ºC, and the Weather Network isn’t forecasting anything quite that warm in the next two weeks.

Lake of the Woods Ice Patrol is celebrating some growth this spring.

It’s been busy: I’ve written 47 blog posts in 49 days, reviewed over 600 photographs, and processed and posted about 175 of them.

Ice Patrol hit new highs for numbers of visits, shattering the old mark of 10,000 visits in a week by hitting 14,000 last week and topping 16,000 this week.

Comments have increased too, offering more reports and fresh insights.

I had more help this spring. As always, my coworkers at MAG Canada pitched in, and this year over a dozen guest contributors sent in waterfront pictures or aerial photos. This helped immensely, allowing Ice Patrol to cover more of the lake and filling gaps in my flight schedule.

Thanks, everyone!

May 9, 2018: Minaki

John Sweeney and Andy Zabloski flew today and returned from the north in the afternoon, so they helped me out with some pictures of the Minaki area.

Big Sand Lake, north of Minaki. Wind has driven the last of the ice to the shore.

You can click on any of these pictures to see a high-resolution, zoomable version.

The south end of Big Sand Lake and all of Sand Lake, with Minaki visible near the left side.

Sand Lake, with Minaki closer to the center of the picture. That white streak near the horizon is ice on Shoal Lake.

Winnipeg River, with Kenora in the distance, above the center of the photograph. The narrow lake near the top left corner is Lower Black Sturgeon, and the white patch at the top right corner is ice on the south part of Lake of the Woods.

In other news, the footbridge to Coney Island came out this morning. That’s scheduled when the waterway from downtown Kenora is otherwise open all the way to Devil’s Gap.

A quick glance at the start of my own flight at twilight revealed that there are some boats in the water at Northern Harbour. We didn’t look at more distant parts of the lake, because there wasn’t enough light to distinguish ice from water.

Satellite images from the last two days have not been good. I’d like to see what’s going on with ice on the southern parts of Lake of the Woods, but cameras on both Aqua and Terra satellites have been thwarted by cloud cover. Some parts of the lake can be glimpsed through gaps in the cloud, and do show the ice darkening, but we haven’t had a really clear image since May 7th.

Tomorrow I’m scheduled for a training flight, so I hope to get a better look around.

 

May 3, 2018: Winnipeg River

My flight today didn’t take me over the lake or close to Minaki, but we did briefly fly north of Kenora, so I did manage a couple of shots of the Winnipeg River from the south end.

The first picture looks north west from over the north end of Dufresne Island. The white stuff near the nose of the airplane is just a wispy little cloud. Locke Bay and Muriel Lake are in the middle distance. Still some ice there.

For this second shot, we’ve turned more north, so you can see Big Sand and Gun Lake near the horizon. Both are frozen. Closer to the foreground are the mouth of Locke Bay and Laurenson’s Island. The streaky bits at the bottom are the same cloud as in the previous picture.

That’s as close to Minaki as we went before we needed to turn towards the airport.

This is Lower Black Sturgeon, seen from the west. The ice there is melting along the shore and looks like it could go completely in the next few days if we stay warm and sunny. Silver Lake, visible in the distance, is a deep lake and will take much longer.

Kenora has three suburban lakes: Rabbit Lake, Round Lake and Laurenson’s Lake. I photographed Laurenson’s the other day, and it was starting to go. Today Round Lake, the smallest of the three,  went completely in a matter of hours. In the morning it was icy. By lunchtime it was opening up, after lunch there was only a small patch of candled ice at the downwind end.

I will be out of town for the weekend starting tomorrow, so there will be no fresh pictures for a few days. I won’t have access to my desktop computer, only my tablet,  so I will be limited  guest photos, if there are any, and updating the satellite links.

I expect the thaw will carry on without me.
