Wild Rose Hatchery is the Wisconsin Department of Natural Resources’ largest coldwater fish hatchery, and its renovation is a key part of Wisconsin’s fish stocking program. This first phase of construction includes a new building to house the broodstock and provides four pavilions each with four raceways to incubate eggs and raise them to stocking size. New deeper, larger wells were drilled to pump groundwater to be filtered and re-circulated through the pavilions, making more efficient use of groundwater. The visitors center incorporates four historic buildings from the hatchery and uses live aquariums, video, and other displays to help tell the story of Wild Rose then and now.
Phase II included a cool water nursery building, 14 modern rearing ponds (six half-acre size and eight one-acre ponds, all eight feet deep with 3:1 slopes), a water reuse system, and a new wastewater system that will clean water leaving the hatchery before it enters the Pine River, a Class 1 trout stream.
