Fishing WisconsinGovernor Tommy G. Thompson State Fish Hatchery
The Governor Tommy G. Thompson Fish Hatchery is not only the state's largest cool water facility, it's the world´s largest musky hatchery. But this automated hatchery has no problems living up to those kind of standards. In many years, the hatchery produces more than half the muskellunge and walleye stocked throughout the state. With 46 rearing ponds, the facility may produce 1.5 to 2.5 million small walleye, 25,000 to 100,000 larger walleye, 35,000 to 60,000 large musky, and 10,000 to 30,000 large northern pike in a typical year.
Visitor Center: 8 a.m. to 4 p.m., Monday through Friday (Please call ahead to schedule a tour).

The public is welcome to visit the visitor center year-round where you'll learn about water ecology and fish rearing by viewing the incubators, rearing ponds, and educational exhibits.
From late April to Labor Day, call ahead to schedule a tour of the production facility, observe first hand the egg incubation operations and possibly view some of the hatchery fish before they're stocked into Wisconsin´s waters.
Spooner's Memorial Park is located off Highway 253/63. Picnic facilities are available and the hatchery is only a short walk away. The area below the Spooner Dam is excellent for fishing and is equipped with two handicapped accessible fishing piers.
Between the park and the hatchery, three piers offer great fishing and handicapped accessibility on the Yellow River Flowage. A boat launch, parking area and restroom facilities are also available on park property.
The hatchery first opened back in 1914 but was completely renovated in 1995 when the 4,568-square-foot building was replaced by a state-of-the-art 14,000-square-foot facility with room for a large drive-through incubation area, offices, conference room, prep room, and visitor center.
Hatchery workers collect, fertilize and transport more than 100 million eggs from the wild to the hatchery during the spring. After the eggs have hatched and grown, they are soon transferred outdoors to one of the forty, one-acre ponds or six, half-acre ponds.
When the fish are ready to be stocked out, the rearing ponds are drawn down so that the fish can be netted or dipped out. The fish are then loaded onto transport trucks, kept alive with the use of compressed oxygen, and hauled to their stocking site.
The majority of walleye produced here are stocked in northern Wisconsin. Musky and northern pike are widely distributed from the north to south.
