The Great Plains FWCO, in cooperation with South Dakota Department of Game, Fish, and Parks, is conducting an acoustic telemetry in Lake Sharpe, South Dakota, to understand habitat use, movements, emigration, and survival of stocked paddlefish. This information will aid in restoring this native species to this segment of the Missouri River and to help determine the feasibility of creating a recreational fishery for paddlefish in Lake Sharpe.

The Great Plains FWCO also provides expertise and identification of the aquatic nuisance species, Didymosphenia geminata, commonly known as “didymo” or “rock snot.” Our laboratory accepts samples of suspected didymo for the purpose of identifying and verifying the diatom. We can also answer questions regarding didymo ecology and its interaction with aquatic resources.
