Rattlesnake Lake
Catch-and-release only and selective gear rules are in effect. Electric motors are permitted. The lake is stocked with both catchable- and fry-size Rainbow Trout that are stocked in the spring, as well as a small allotment of jumbo triploid Rainbow Trout. The water level of the lake fluctuates significantly during the summer months depending on the accumulated snowpack in the mountains. A well-developed park on the east shore has ample parking, toilets and a small gravel boat ramp.
