Lacreek National Wildlife Refuge was established in 1935 as a refuge and breeding ground for migratory birds and other wildlife. The refuge is located in Bennett County in southwestern South Dakota. The refuge lies in the shallow Lake Creek valley on the northern edge of the Nebraska Sandhills and includes 16,410 acres of native sandhills, sub-irrigated meadows, impounded fresh water marshes, and tall and mixed grass prairie uplands. The refuge serves as an important staging area for migrating Canada geese, other waterfowl, sandhill cranes, shorebirds, and neotropical migrants. Providing critical wintering habitat for the high plains trumpeter swan population is a primary goal. The refuge provides a variety of habitats for resident and migrant wildlife.
