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.

Resource managers should consider the law of “limiting factors” if they have any hope of saving the imperiled delta smelt
It’s not lost on those concerned with the environmental health of the Sacramento-San Joaquin Delta and adjacent upper San Francisco Estuary that efforts to reverse declines of its imperiled fishes are failing. All the region’s fishes that are protected under the federal Endangered Species Act appear to have suffered reductions, some dramatic reductions, in abundance over the past two decades. The failure to respond to a native fishery in crisis falls in substantive part on the collective shoulders of the well-funded scientific community. From long-term surveys incapable of accurately monitoring the status and trends in numbers of those imperiled fishes to laboratory studies that can’t possibly mimic in-situ estuary conditions,
