Lila Warren at the USGS Tennessee Cooperative Fishery Research Unit holds a muskellunge fish. To prevent the disappearance of muskellunge from the Cumberland Plateau, the Tennessee Wildlife Resources Agency (TWRA) began stocking muskellunge into the upper Caney Fork River system above Great Falls Dam in 1976.

Areas like this tidal freshwater swamp, along the Pocomoke River in Maryland, provide important ecosystem services including improving water quality by trapping watershed sediment before it reaches the Chesapeake Bay. However, a sediment shadow along tidal rivers may limit their resilience to the impacts of sea level rise.

Thousands of young Atlantic salmon are released into the St. Regis River system (a tributary of the St. Lawrence River) in an effort to restore this diminished Lake Ontario fish population. The salmon were reared at the USGS Tunison Laboratory in Cortland, N.Y., and are released by USGS scientists and members of the Mohawk Tribe.
