Caption

Mono Basin is a closed hydrologic basin spanning the border between California and Nevada. Los Angeles has been diverting streams since 1941 that normally would flow into Mono Lake. It has been predicted that continued diversion will have major ecological consequences for the natural resources of the Mono Basin National Forest Scenic Area. This book studies the ecological risk assessment that considers the effects of water diversions on an inland saline lake. It examines the hydrology of the Mono Basin, investigates the lake's physical and chemical systems, studies the biological relationships, and predicts the effects of changes in lake levels on the ecosystem.
