Flavs, smaller PMDs, evening caddis blooms and diminishing brown drakes are the fare on the upper river. On the lower river we are beginning to leave the early season mayfly emergence peak. Gray drakes are present but diminishing. PMDs are present in good numbers, but their size is decreasing. So go to #18’s-22’s of your favorite dry, emerger, cripple and spinner patterns. Evening caddis emergences remain strong here. Beetle and ant patterns are always good around overhead cover and along banks. We are not far from the days when hoppers will be a major food form for trou up and down the river.
