Grays Lake National Wildlife Refuge has the largest hardstem bulrush marsh in North America. Located in a high mountain valley near Soda Springs in southeastern Idaho, the refuge and surrounding mountains offer incredible scenic vistas, wildflowers, and fall foliage displays. Lands adjacent to the 19,400-acre (79 km2) refuge are primarily wet meadows and grasslands. Grays Lake Refuge provides breeding habitat for over 200 species of mammals, birds, fish, and amphibians.


The refuge has a surface area of 20,125.08 acres (81.44 km² or 8,144 ha).[2]

Bird habitat

The refuge hosts a large nesting population of greater sandhill cranes; as many as 1200 individuals are counted in the valley during migration and staging times. The refuge is a birding destination, and a good area to view the rare trumpeter swans. This near-pristine montane wetland is being threatened by the same type of suburban/rural development that has so heavily impacted nearby Jackson Hole.
