First derby of the year will be late April on pool 4. Have not fished it for bass only walleye. We will be going out of Wabasha. Just looking for a starting point. I think we are going to be targeting both smallies and largies. Does the water warm earlier upriver because of the power plant or does that not paly as much in the spring because of the runoff? Also I'll be practicing a few days prior to the tournament and should have a open seat in the boat a day or two. Thanks for the info.
