Hosmer Lake is open to fishing all year. The district office contunies to receiver positive reports on fly angling for Brook and Rainbow Trout. Fish are currently spread out between the upper and lower lakes and the channel. Callibaetis and damsels are an integral part of the diet at Hosmer, and we recommend anglers stock their fly boxes accordingly. Restricted to fly-fishing only with barbless hooks. Catch-and-release for all species.
