The reservoir was stocked mid-May. The reservoir is accessible for both entrances and is full. There have not been any fishing reports, but the reservoir got very low last year and holdover rainbow trout are probably few and far between. Trolling with flies and lures is going to be your best bet as fish might be spread out due to high water. Bank fishing can also be productive. If not catching fish try moving around the reservoir to find where they are feeding.

There are largemouth bass in the reservoir and will provide a good opportunity for anglers as the water temperature warms in June.
