UPDATED August 30, 2024:

Russian River Temporary Urgency Change Filed

Sonoma Water filed temporary urgency change petitions with the State Water Resources Control Board Division of Water Rights requesting approval of temporary changes to water right Permits. The petitions seek authorization to implement a hydrologic index based on Lake Mendocino storage values, rather than the current index based on cumulative inflow into Lake Pillsbury, starting November 1, 2024. In the absence of the proposed changes, the applicable minimum instream flow requirements may require releases of water from Lake Mendocino and Lake Sonoma at levels that would risk significant depletions of storage levels that could cause impacts to human health and welfare and reduce water supplies needed for protection of listed salmon species in the Russian River. Therefore, Sonoma Water proposes alternative monthly storage values, in lieu of cumulative Lake Pillsbury inflow, to define the water supply conditions that determine which minimum instream flow requirements.
