My criterion for mid-winter small pond success has always been two consecutive days of 70-degree temperatures. We just had two days in the mid-60s followed by one day of 58 degrees. Close enough. I went fishing. White/silver Mini Minnies counted down to 2 1/2 to 3 feet brought 12 bluegills of 7 to 7-1/2 inches to hand before rain disrupted the fun. My new criterion for mid-winter success is: Two 60s + one high of 50 equals two 70s.
