Beautiful sunrise shot you got. And that is one WIDE crappie you're trying to stuff into the checker.
Regarding the warmer water, I've been finding them deeper than usual, just above the thermocline layer, out away from the usual edges and weed lines in the ponds I fish. Not the deepest main basin but sort of on the shelf between the incline up to shallower water and weeds, and the drop away in to the main basin.
