18F at 6am this morning at Watermans Lake. Edges were 2 inches of solid black ice and about 10 feet out was 4-8 inches of solid black ice on the entire lake. The ice was so perfect but dangerously slippery even with cleats!!! I went down hard on my left knee at one point while getting excited about a flag going off!!!! Me and my boy ZT33 fished from 6:30-2:30pm. Had about 20 flags 2 small pikes (2.5 LB/4LB), 4 pickerel (one was 3 pounds), 4 pound Large mouth, and 3 yellow perch. It was a nice day out there today.
