Gavins Point National Fish Hatchery was built by the U.S. Army Corps of Engineers, following construction of Gavins Point Dam. The purpose of the hatchery is to help maintain fisheries in the Missouri River Basin, following impacts to natural river flows and loss of habitat due to development and channelization of the Missouri River Basin. Hatchery staff rear threatened and endangered fish species, including the Pallid sturgeon and American paddlefish; and rear and stock many game fish species including walleye and yellow perch throughout the Missouri River Region. Proximity to a Corps of Engineers recreation site make this an attractive point of interest including trails and self-guided tours of the hatchery. A large-scale aquarium includes thirteen indoor tanks which display many of the fish, reptile, and amphibian species found in the Missouri River basin, along with informational displays on endangered, threatened, and unusual species.
