Workshop equips park rangers with tools of the trade
U.S. Army Corps of Engineers Nashville District park rangers overlook the Bio-Acoustic Fish Fence at Barkley Lock March 6, 2024, on the Cumberland River in Grand Rivers, Kentucky, during the Park Ranger Workshop. The BAFF is designed to deter or guide fish using sound, strobe lights, and air bubbles. It is located in the downstream approach channel and may deter invasive carp from using the lock to move into Lake Barkley. (USACE Photo by Ler Roberts)
