Location Information

Monarch Pass Lakes (Waterdog, Boss, Grass)

Along the eastern flank of Monarch Pass and to the north of US Highway 50, several glacial lakes stand at elevations of about 11,000 ft. Often among the first of the higher lakes to ice off, each of these is reached by a short steep trail from Highway 50 (45-60 minute walk). Waterdog Lakes are the southernmost, three in number, along with a few shallow tarns. Grass Lake lies in the middle, a small but relatively deep lake with an excellent cutthroat population, and is probably best approached from a float tube. Boss Lake is a natural pool that was enlarged with a dam long ago. It has a vibrant population of Greenback Cutthroat hybrids.

Special Regulations Apply – Artificial flies and lures only. All cutthroat trout must be returned to water immediately.
