Northern VA, WVA Campgrounds with Water Access?

I don't mind VA, WVA, or PA, but I try to avoid MD whenever possible.

To each his own, but if you're 62, Maryland State Parks allow even out-of-state residents to get free day use & half-price camping Sun-Thurs with its $10 Senior Pass. That's a better deal than my own state gives me, and the parks I've tried have been pretty good, although maybe not for shooting.
