Document Description
The Agency is in the process of preparing a Supplemental EIR to the WSTSP Final EIR. The WSTSP consists of three separate components which together would meet the project objective of providing a safe, economical, and reliable water supply to meet the defined future water supply needs in the Agency's service area: 1) Water Conservation Component: savings approximately 6,600 acre-feet per year (AFY) and expand the water education program, 2) Russian River Component: increase the amounts of water released from Lake Sonoma and diverted from the Russian River by 26,000 AFY, increasing the total authorized amount of diversions from the current limit of 75,000 AFY on transmission system diversions to a new limit of 101,000 AFY on all diversions from the lower Russian River under the Agency's water right permits, 3) Transmission System Component: increase capacity by 57 million gallons per day (mgd), thereby increasing the total capacity from 92 mgd to 149 mgd (plus 20 mgd of standby capacity).
