Clohesy Lake is one of the lesser visited alpine lakes in the San Isabel National Forest. Right on the Collegiate Wilderness Boundary, Clohesy Lake is fed entirely by snowmelt and supplies a lot of the water flowing into Clear Creek (and thus the reservoir).
If you are looking for a tougher run, you can try to journey further up the basin on a wilderness trail towards Peach Lake, or you can travel off-trail and climb Missouri Mountain from its northwest ridge. The OHV road and trail leading to the lake are very runnable, but journeying further onto the wilderness trails is a different story.
