We support scientific research to improve water resources management and policy with the ultimate objective of improving the lives of Californians and protecting California’s natural resources. Investigators who receive funding from the Center for California Water Resources Policy and Management carry out studies using data on the imperiled native fishes and environmental factors in the Sacramento-San Joaquin Delta to evaluate management-relevant hypotheses, quantitatively relating the performance of species listed under state and federal endangered species acts to their dynamic, degraded habitats. The Center also funds research aimed at providing guidance to the fish and wildlife and water-resource agencies regarding standards of conservation practice.
