Drake hatches in the Last Chance-Harriman stretch are pretty much over. Now it is on to flavs with PMDs. During these hot dry days fishing early morning spinner falls with your favorite rusty spinner pattern is not only pleasant but productive. The river below Ashton Reservoir is warming meaning slowing action. Evening caddis activity and AM spinner falls is best time to fish. Below Chester Dam irrigation demands have lowered and warmed the river to the point it’s hardly worth a visit. There is some action on the Flat Ranch section of the Henry’s Lake Outlet section for those folks using PMD life cycle and dry damselfly patterns. But if a bigger early season flush had taken place a lot more fish would be present.
