From the Confluence down the river is running at summer flows which is about 2600 CFS most of this is flowing out of the CleElum reservoir. This can be tough for wadding but above the Confluence the Yakima is running at about 200 CFS easy wading. So I’m the high water nymphs are working best with small size 16 lighting or a chubby drake nymph.
From Thorp to Rosa fishing has been good the best has been fishing large soft hackles in the rock gardens and swinging off to buckets of to the sides of ruffles. Also end of islands running a double stone nymph setup.
From below the Cle Elum reservoir to the confluence:river running high not good for wadding if any fish to be caught would be in deep slow water we recommend not fishing the Cle Elum at this due to dangerous water and not many fish!
