This fishery resides on USFS Sawtooth National Forest. Access is typically limited in the spring until a naturally formed snow drift is reduced or plowed opening up access to the lake and camping area. Spring access (and stocking access) varies year to year depending upon snowpack but typically opens up late May to early June. The lake carries some stocked trout over the winter providing some larger sized fish; however most fish will be in the 10-12 inch size class.
