Mortenson Lake National Wildlife Refuge

The wetlands of Mortenson National Wildlife Refuge provide important water resources that support resting, nesting and foraging areas for migratory birds in the semiarid environment of the Laramie Plains basin. The three Laramie Plains refuges, Bamforth, Hutton Lake and Mortenson Lake are designated as Important Bird Areas by Wyoming Audubon.

The Refuge is administered out of Arapaho NWR in Walden, CO. It is closed to the public because of the Wyoming toad's endangered status.
