Due to such a cold winter, the forecast is for a cold wet Spring and Summer. Taking into consideration the thickness of the ice on Pymie, you'll be lucky to be wading by mid April. There's a good two/three weeks of ice fishing season left, with up to 15 inches of ice to melt.
Sorry, I don't see anyone "holding their breath" to go wading for walleye just yet. This year I'll say they'll be wading by the last week of April.
