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.
Largemouth bass bite is also turning on and will improve in coming weeks. More fish are in the tract, but the larger fish will be found in the sloughs. Best fishing is from 11am to 4pm. Hatches of midges and a few callibaetis have some fish on the surface midday. Use a long leader with 6-7x tippet.
