Minidoka National Wildlife Refuge extends upstream for 25 miles along the Snake River from Minidoka Dam and includes all of Lake Walcott.
About 2/3 of the reservoir is wildlife sanctuary, attracting thousands of breeding and molting waterfowl and other waterbirds. The refuge provides good opportunities to view them and many other forms of wildlife. About 1/3 of the lake is open to boats April 1-Sept 30. Fishing can be good at times. Portions of the refuge are open to waterfowl hunting. Birding is best during spring & fall migrations. Camping and day use are nearby in Lake Walcott State Park (208-436-1258).
