Dale Hollow National Fish Hatchery was established to mitigate for fishery resources which were lost due to the construction of federal water development projects in the Southeast. This is accomplished by stocking rainbow, brown, lake, and brook trout in waters impacted by federal dams. Stocking trout in public waters supports a significant recreational fishery which generates a substantial amount of economic activity for local and regional economies. This facility is also involved in the conservation of imperiled, freshwater, non-game fishes, and mussels.
