State Water Resources Control Board

The State Water Resources Control Board (the State Water Board) was created by the Legislature in 1967. The mission of the Water Board is to ensure the highest reasonable quality for waters of the State, while allocating those waters to achieve the optimum balance of beneficial uses. The joint authority of water allocation and water quality protection enables the Water Board to provide comprehensive protection for California's waters.

The Water Board consists of five full-time salaried Members, each filling a different specialty position. Each board member is appointed to a four-year term by the Governor and confirmed by the Senate.

There are nine Regional Water Quality Control Boards (Regional Boards). The mission of the Regional Boards is to develop and enforce water quality objectives and implementation plans that will best protect the beneficial uses of the State's waters, recognizing local differences in climate, topography, geology and hydrology.

Each Regional Board has nine part-time Members also appointed by the Governor and confirmed by the Senate. Regional Boards develop "basin plans" for their hydrologic areas, govern requirements/issue waste discharge permits, take enforcement action against violators, and monitor water quality. The task of protecting and enforcing the many uses of water, including the needs of industry, agriculture, municipal districts, and the environment is an ongoing challenge for the Water Board and Regional Boards.

ICE works with the State Water Resources Control Board (SWRCB) on a number of projects dealing with water quality, watershed planning, and information technology.

Big Springs Creek

In 2008, Center researchers seized a rare opportunity to quantify the results of conservation action on a large scale. The Nature Conservancy bought ranchland along Big Springs Creek, a Shasta River tributary that had been degraded by cattle grazing. The conservancy continued ranching but fenced out cattle along the 2.2 mile stream.

Delta Consumptive Water Use Comparative Study

This research project was convened by the Center for Watershed Sciences at the University of California Davis with financial support from the California State Water Resources Control Board Office of the Delta Watermaster and other agencies. Its objective is to develop a better understanding of consumptive water use in the Delta by coordinating modeling, measurement, and other information from a variety of independent research and estimation efforts.

California Environmental Flows Framework

The California Environmental Flows Framework (CEFF) provides an approach for determining ecological flow criteria and guidance for developing environmental flow recommendations that can accommodate a variety of stream types and biological communities, while supporting regulatory and management agency programs aimed at protecting beneficial uses for aquatic life. CEFF applies a Functional Flows approach and provides ecological flow criteria based on the natural variability of ecologically-relevant functional flow metrics. It provides a process for considering physical and biological constraints within a stream system and provides guidance on developing environmental flow recommendations that balance ecological and water management objectives.

Addressing Nitrate in California's Drinking Water

One in 10 people living in California’s most productive agricultural areas is at risk of exposure to harmful levels of nitrate contamination in their drinking water, according to a report released today by the University of California, Davis. The report was commissioned by the State Water Resources Control Board.
