Perch fishing has been good on Lake Winnebago. There's about 8 to 12 inches of ice; the snow insulated it in some areas and therefore ice thickness varies. There were reports of good numbers of white bass being caught on Lake Poygan last week. The northern portion of Green Bay remains basically ice-free. Many Lake Michigan tributaries and harbor areas have some ice cover. With forecasts calling for rain and high temperatures in the mid-40s by this weekend, conditions could change rapidly. The Milwaukee River remains open near the harbor and shore anglers have been catching a few brown trout. In Racine water levels on the Root River have dropped considerably since last week, and flows are now good for drift fishing. There are fair numbers of brown trout and a few steelhead in the river.
