Reservoirs behave like large natural stillwaters with extra wind and, often, extra boats. Bream and pike are the usual coarse targets; some are trout water with extra permits. Distance and accuracy matter.
A cage feeder to a plateau, a deadbait in a bay, or a lure along a dam wall are typical. Don't assume commercial-style F1s. Don't assume you can fish without the extra ticket.
Typical species
Bream, pike, perch, roach, occasional carp and zander on some waters. Trout on others — that's a different licence conversation.
Tactics
Cage feeder at range for bream. Deadbaits and lures for pike. A bomb on a marker you've actually found.
Etiquette
Boat anglers, bank anglers, and birders share these places. Follow the permit. Don't block slipways.
Close season & rules
Usually no statutory coarse close season on the stillwater itself. Trout seasons and club pike rules still apply. Check the permit, not a guess.
