The Nampa Fish Hatchery is a resident trout rearing facility located on the south end of Nampa at the intersection of South Powerline Road and Locust Lane. From Interstate 84, take Exit 38 to Highway 45 and travel west through the city of Nampa and then south on 12th Avenue towards Melba and the Snake River. Turn east on Locust Lane and north on Powerline. Nampa Hatchery was constructed in 1975 and later purchased by Idaho Fish and Game Department in 1982. This hatchery is the second largest hatchery in the state's resident hatchery system. It raises and stocks fish in every region in the state, providing catchable sized rainbow trout for redistribution from McCall, Hayspur, Sandpoint, Mullin, Clearwater and Sawtooth hatcheries.
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, three fingerling/broodstock raceways and 10 production 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.
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, church groups and local scout groups by calling (208) 465-8479 for scheduling date and time. Disabled veterans from the Boise Veteran Hospital, handicapped patients from the Idaho State School and local nursing home residents are allowed to fish the settling pond during the summer months by appointment. A fishing clinic is held each year at Nampa Hatchery on Free Fishing Day to introduce new anglers to the sport of fishing. Wilson Springs Pond across South Powerline Road west of the hatchery provides anglers, young and old, with excellent year round fishing opportunities.
Rainbow trout comprise about 90% of the trout production at Nampa Hatchery. Lahontan cutthroat, brown trout, and Fall Chinook are also reared at Nampa Hatchery. During the early fall, hatchery personnel operate a kokanee salmon trap on tributaries to Deadwood Reservoir or Anderson Ranch Reservoir. Fertilized eggs are shipped from the trap site to Mackay and Cabinet Gorge Fish Hatcheries for rearing and eventual return to Idaho waters. During the month of November hatchery personnel plant adult steelhead from Oxbow Fish Hatchery in the Boise River, creating a very popular fishery for local anglers.
