Why does the Fish and Wildlife Service stock non-native fish?
The habitat that exists in Lake Sakakawea was not found in the old Missouri River system. Consequently, the fish that are native to the river have not adapted to these conditions. Fish species more suited to the lake were introduced from the Hatchery to fill the niche. Chinook salmon, trout, and smallmouth bass provide anglers with unique fishing opportunities. Without the reservoirs, these species wouldn’t exist in the Missouri River.
