Three Creeks Lake is still good, and ought to be for at least another month, maybe longer. I know there was still a pretty strong callibaetis hatch last week but I doubt this will last much longer at 6500 feet. If you go this week be ready with all stages of callibaetis. Leeches and Chironomids, Beetles, Ants, scuds and Waterboatman will be taking the stage away from the mayflies as we progress into fall. The Store is closed and boat rentals for the year are done. The lake is really quiet now and on a cooler weekday you might be one of very few people there.
