I’m a local, and how Big Windy decides to play will all depend on how much snow we get and how bad the wind is between now & then. Another big factor this year is the high water levels. We are currently flooding up here. If you have ever been to Selkirk the blue bridge in town is currently closed due to the high water that has flooded the east side.
I split my time on the lake between the quad & truck. You can pretty much guarantee that at least 1 trail will be broken from either Balsam or Warner no matter the conditions. Arrive early at any of the access points and you should be able to follow the convoy out. Depending on the freeze, your truck will get put through the ringer. Make sure you have a good recovery strap.
As mentioned in the posts above, do not take Lake Winnipeg lightly, You need to be prepared for the worst. The wind can pick up quickly and you can be in a complete white-out in minutes.
I run the Ice Fishing Manitoba FB Page and there will be countless updates on access conditions and travel.
