The big flows during summer usually mean this stream/lake/impoundment doesn't fish consistently. It can be tough. Find the ledges and drop off and fish small Pheasant Tails and midge patterns. Try stripping olive or black Wooly Buggers. Some swirls will hold fish too. If you do try this body of water, watch the flows.

Stripping leeches and buggers on a type VII full sink line works great here. Fish going over 20" happen! Releases out of Shasta Dam have been stable. Good place to hire a guide though. Finding these fish requires some special knowledge and a boat.

Indicator suspended Birds Nests, Midges, PT Nymphs should work along the edges of the fast water near the Dam. Suspend your flies about 2-3 feet below the indicator. These fish like to come up to the fly. Fish the shallow edges. Stay low!! You will need a motorized boat to get to where the good fishing exists.
