When visiting the hatchery, you can take a self-guided tour of rearing tanks where 325,000 brook and brown trout are raised each year. Although there are no picnic facilities on site, you can find camping and picnic areas at the nearby Interstate Park. Additionally, the city of St. Croix Fall's hydroelectric dam and viewing area are a one-quarter mile north of the hatchery.
Since 1919, cold, clear water and a lot of improvements have helped to make St. Croix Falls hatchery one of Wisconsin´s primary trout brood stations. As a brood station, adult trout are kept on the property and their eggs and sperm are collected each year to produce fertilized eggs.
About 1 million brown trout eggs and 600,000 brook trout eggs are produced at St. Croix each year. Although many of the eggs are transferred to other Wisconsin hatcheries, about 700,000 trout are raised at this hatchery annually for stocking in Wisconsin's waters.
Once a year in the fall, brook and brown trout are spawned. After approximately 50 days, by spring the eggs hatch and the fish will have grown to yearling size.
