I'm near Bedford, S of Lake Monroe, but the pond is in a pretty wooded ravine in an area of rolling wooded hills. Stays fairly cool. Bottom water never got over 52F last summer even with top water in 70s. Will be different this year with aeration.
Fish are only 1 yr old, so don't know if they might behave differently than a mature ecosystem. Just glad they wintered ok, and starting to eat a bit. Not going to push them, the water is very green and still tons of minnows and late year spawn BG, so everyone has something to eat. Glad your fish are active tho!
