Devils Hole is not a trickle, unless you happen to go during a really bad drought. Usually fishing up from the trail will produce fish and it is a mixed population, though the last couple of times I didn't catch any brookies down the lower end.
It used to be that below the falls as you moved upstream you started catching predominately brookies, then above the falls it was all brookies. It may be changed from that, at least the evidence tells me maybe the upper end is the only place to catch brookies.
In a good year there is plenty of flow. I've been told that some years when there is a serious drought the pools can be separated by bare rock. It is easy to wade, and there's plenty of casting room. Fish grow to nice sizes there, it's worth the trip. As of right now there are hatches of sulphurs probably just starting, after that there are several species of cahills, then in late June there are yellow drakes. There may even be green drakes there, but I've never seen them but know a couple of other streams in the area that have them. Yellow stones in #14 will be hatching all summer, and there will be various sizes of tan caddis hatching sporadically. Then in fall the fall caddis. But a big stimulator will catch 'em too.
