Big stoneflies are flying and laying eggs in Box Canyon. This has helped thinned out the fishing pressure on the lower river. Some of the big stoneflies remain flying on the lower river and golden stoneflies to begin doing the same any day now followed by green drakes. Do not overlook early and late day caddis activity anywhere on the river. If you want to escape the stonefly madness, consider trying the river on the Flat Ranch Preserve. We call it ” Henry’s Lake Outlet”, but the USGS calls it the “Henry’s Fork.” Most of the larger fish within it are Henry’s Lake escapees, so present what you would in Henry’s Lake for now.
