I just came across a great article in Virginia Game & Fish magazine from July 2004 while sitting in the waiting room of the VA Hospital. It's all about the Flathead fishing in the Richmond area in July. According to the guide that was quoted in it, you can ecepct about 30 hits in a few hours on Flaties down there, with fish in the 30# range very common. They talk a lot about the area right in downtown Richmond but I know there are a bunch of good areas from Lynchburg to the Bay. So, no it's not too hot for Flatheads.
