Anne and I hit a resevoir yesterday and we couldn't swing a dead cat without hitting a fish. Perch, bluegills, pickeral, crappie, bass...they were all very cooperative. We fished from two hours before to two hours after noontime, then went home for a nap and a great dinner.
Adrian, this was on the upper (or as they call it here, the lower) resevoir from where we went back in July. Same results, but much cooler temperatures.
