Flows continue to drop into the 240-270 cfs range and the river is warming up to 71 F at Delta. With these conditions, fish early-early, or late-late. Head up higher towards Lake Siskiyou where the river runs cooler for your best chances. Fishing the deeper runs with rubber legs and golden stones is producing some hookups. If you are up high, midge patterns will work.
A good fly box will have various sizes of Parachute Adams from #14 - 18, Dark Stonefly Nymphs in #6-8, Black Midge Nymph Patterns and #12 Bird's Nest, #18 Gordon Prince Nymphs. See suggested fly patterns in the accompanying sidebar for reference.
The morning mayfly spinner fall and hatches should keep you occupied hooking fish on dries until midday around Spring Creek.......
