Henry’s Fork, June 8th, 2024

Golden Stone

Giant stone flies are on the wane on the lower river, but golden stone flies are coming on. With the current warm weather giant stone flies are flying through the upper river. With that going on and because of our almost ever present wind, dry stonefly patterns will be effective through the upper river. Remember: trout are in the water 24/7 and with wind spreading the bugs to all the river, fish will respond to correctly drifted patterns even in such as the Last Chance and Harriman locations because of canyons above and below. Soon big stonefly and golden stonefly activity will be gone, caddis activity will stay strong, then the mayfly season will begin with unequaled activity of various species from drakes to smaller versions, all that makes the Henry’s Fork so famed.

Currently good water quality reigns in temperature and clarity throughout the upper river and on downstream at least to Chester Dam. From this location, Fall River brings in run-off water in amounts that compromise this status.
