Good flows below the Afterbay are 2000 cfs or below. Concentrate on fishing the riffles and behind spawning steelhead. Also, try swinging a streamer, steelhead, or salmon alevin pattern with a caddis dropper on a sink-tip or full sink line. Concentrate on fishing from the Hwy 70 bridge to the fish hatchery and cover a lot of water. Access low flow section at Bedrock Park, Montgomery St., Arlin Rhine Rd, the fish hatchery, or the Oroville Wildlife Area off Dam Blvd.
Fishing is fair to good.
Warmer and clearer water is turning the bite on. Concentrate on water 7-12 ft deep. Vary your retrieve and change flies until you find the magic combo. Repetitive casts of 70' plus are most effective. Wind can be a factor.
