The Garrison Dam National Fish Hatchery is the world’s largest walleye producing hatchery with ten million fingerling walleye released annually in North Dakota and Wyoming. This hatchery’s role in fish restoration and recovery includes spawning and stocking of endangered pallid sturgeon in the Missouri River as well as restoration of sauger and shovelnose sturgeon in Wyoming. Springtime at the hatchery is particularly interesting with millions of eggs incubating from a variety of fish species. In addition to providing a role in managing fish population for North Dakota's salmon and trout fishery, it also fills stocking requests for walleye, northern pike, and a variety of other coolwater species in the Dakotas, Montana, Wyoming and Idaho. In October, a stroll down the hatchery’s trails offer a glimpse of salmon as they make their way upstream to spawn. Visitation is welcomed. Cross country skiing on groomed trails, hiking or biking is encouraged when the conditions permit.
