Water Right Permit Extension

The Mokelumne River is the primary source of water for more than 1.3 million EBMUD customers. EBMUD's right to provide this water is based on the terms of two state water rights: a license and a permit per the State Water Resources Control Board, who issues permits and licenses to divert water.

In 1956, the State Water Resources Control Board issued water rights Permit 10478 to EBMUD to support East Bay water needs and allow diversion of 125 million gallons per day of water from the Mokelumne River to the East Bay. This water supplements EBMUD's senior water right which was issued in 1926 and licensed in 1981. In 1964, EBMUD built Camanche Reservoir to use water diverted under Permit 10478.

The term of the permit required that water be fully beneficially used by December 1, 2000. Long term studies show that water available under the permit will be needed in the future as water demand grows. In November 2000, EBMUD requested a time extension of forty years to year 2040 to continue the terms of existing Permit 10478. In November 2008, EBMUD issued a "Notice of Preparation, EBMUD Camanche Permit Extension Environmental Impact Report."

Draft Environmental Impact Report

EBMUD has now released a draft environmental impact report on the water right permit extension project. There are no new water rights being asked for, no new facilities to be constructed and no changes proposed to how EBMUD operates its water supply infrastructure. The document evaluates EBMUD’s continued use of Mokelumne River water supplies to meet water demands through 2040. The 45-day public comment period which began October 3, 2013 and was scheduled to close on November 18, 2013, has been extended to the close of business on January 10, 2014.

Four public meetings have been held to obtain input.
