Water is supplied by eight pump-assisted artesian wells. A maximum of 30 cubic feet per second of 59° F water is available for fish production. Fish rearing facilities include 16 early rearing raceways and 13 final rearing raceways. Sixteen upwelling incubators are used in the early rearing raceways for eyed-egg incubation. A settling pond treats water flows from the rearing units before discharge into Wilson Springs Pond and Wilson Springs Drain.
12 inch Catchable and 3-5 inch fingerling sized Rainbow trout comprise nearly all of the production at Nampa Hatchery. Lahontan cutthroat trout are also reared to a fingerling size and released. During the early fall, hatchery personnel typically operate a kokanee salmon trap on tributaries to Deadwood Reservoir. Fertilized eggs are shipped from the trap site to Cabinet Gorge Fish Hatchery for rearing and eventual return to Idaho waters.
The hatchery is a focal point for many visitors, tours, and special groups throughout the year. Visitors are welcome daily between 8 a.m. and 4 p.m. Guided tours are provided to area schools, and other interested groups by calling (208) 465-8479 for scheduling a date and time. Wilson Springs Pond across South Powerline Road west of the hatchery provides anglers, young and old, with excellent year-round fishing opportunities.
