East Branch of Clarion River has a bottom release dam just north of Johnsonburg, PA. There is a DHALO section at the beginning of the tailwater and open water below that. The DHALO section has stocked fish, mostly rainbows. There are many small splash dams that create habitat and kayakers use the area quite extensively. The main kayak drop off point is the top of the DHALO. Hatches are not extensive but there always seems to be some top water action. Nymphing probably is the preferred approach.
