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

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!
