Salmon and trout living in California hatcheries are being moved by truck to cooler waters in order to save their population, because of side-effect from the state's acute drought. 

With less snow and other precipitation during colder months this past winter, the temperature continues to rise to lethal levels for fish living throughout the state. Water levels in rivers and streams are now too low and warm for the fish to successfully migrate like they do naturally. 

William Cox, manager with the California Department of Fish and Wildlife's Hatchery Program, explains the process of moving fish to cooler waters and offers his insight into the future of those fish in their new environments.
