Another seasonal change . . .
In my area they draw some of the lakes down for the winter. They lower the water level by as much as 3'. This forces the fish to move regardless of water temp. One benefit is that it increases the amount of shoreline fishing on the main lake. Of course, this also affects the fishing conditions in the rivers and ponds downstream of the lakes. The water level in the carp pond is so high that it's difficult to fish there now.
