Anglers can expect excellent angling opportunities fishing for brook trout and rainbows, 8-10 inches. Brown trout in the 1 to 3-pound range and some much larger are also available. Small kokanee and cutthroat are also taken. A boat launch is available, but all motors are prohibited by county ordinance.

There is a small US Forest Service campground at the lake, and a Forest Service Pass is required for the area.
