Anglers should expect to find fishing success similar to success found over the past few years. Rainbow trout stocking occurred this fall, so trout fishing should be good. Be willing to move around this small reservoir to find active fish. Groups congregate on the Maple Spring confluence and the point on the east of the reservoir, but fish are distributed everywhere. If you’re fishing for bluegill or yellow perch, keep your lures and baits very small. Ice conditions are always changing on this reservoir. It’s fed by two main springs on each side of the reservoir as well as many underwater seeps located throughout the reservoir. These seeps often create holes in the ice, and thin areas of ice, well into the ice fishing season. These seeps are easily found if little or no snow is present because you can see water moving or the snow has a gray color to it. Avoid these areas. The water level will rise through the winter, so the edges may be soft through most of the season. Check the edges carefully before venturing out. Anglers are encouraged to review the Utah State Parks ice safety guide
