About the Refuge

Wyoming Toad 400x

Mortenson Lake National Wildlife Refuge (NWR) was established in 1993 under the Endangered Species Act to support the last known population of the Wyoming toad. The Refuge encompasses 1,776 acres and is located southwest of Laramie, Wyoming. The four main lakes on the Refuge are associated with a series of high elevation lakes called the "Laramie Plains Lakes."  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.
