WSSC Patuxent storage below Triadelphia, with timbered coves, dam-adjacent deep water, and enough pelagic room for landlocked stripers and walleye. Drinking-water operations and restricted shoreline define the habitat more than a recreation-park layout.
Best seasons
- Spring
- Summer
- Fall
Common techniques
- Boat fishing
- Shore fishing
- Spinning
- Trolling
