The construction/implementation phase will begin during the onset of the next drought or when lake level allows for construction (scheduled April 2021), and will end six months from the construction start date (scheduled October 2021). Located on a Federal Facility: The Lake Cachuma Emergency Pumping Facility Secured Pipeline Project Site is located at Lake Cachuma, a Reclamation Project, on Reclamation Land. This application is to request funding for the Cachuma Operation and Maintenance Board (COMB) to develop and construct the Lake Cachuma Emergency Pumping Facility (EPF) – Secured Pipeline Project. The proposed EPF Secured Pipeline Project is a highly critical operational infrastructure project, which will provide a lifeline delivery of Cachuma Project water and imported State Water Project (SWP) water to 200,000 residents on the South Coast of Santa Barbara County during times of drought. The Cachuma Project was originally designed as a gravity flow system, however, when the lake level recedes below the lowest gates on the Intake Tower, Cachuma Project water and SWP water is unable to be transported to the South Coast. Under these conditions, water must be pumped from deeper parts of the lake to the Intake Tower. Without the ongoing operation of an emergency pump and pipeline, water service would be interrupted, causing a widespread immediate threat to public health and safety within Goleta, Santa Barbara, Montecito, Summerland and Carpinteria. In this way, the proposed project is aligned with the goal of the Drought Resiliency Grant Proposal to support a proactive approach to drought by providing financial assistance to projects that will build long-term resilience to drought. If selected, the funds procured will be used to improve drought resilience by designing and constructing a secured pipeline to provide access to an additional 20,500 acre-feet of water for delivery to the South Coast of Santa Barbara County. Lake Cachuma Emergency Pumping Facility – Secured Pipeline Project March 2019 1 <'ZKhEd Lake Cachuma serves as the primary water supply for 200,000 residents in southern Santa Barbara County. The water is purveyed by five water districts; Goleta Water District (GWD), City of Santa Barbara, Montecito Water District (MWD), Carpinteria Valley Water District (CVWD) and Santa Ynez River Conservation District ID#1 (through exchange). Those five water districts comprise Cachuma Project Member Units. Cachuma Operation and Maintenance Board (COMB) is responsible for conveying the four South Coast Member Units water entitlements ( GWD, City of Santa Barbara, MWD, CVWD), including State Water deliveries through Cachuma Project facilities. COMB is the proponent for this project due to their water delivery responsibilities. Water is delivered to the South Coast communities through the Intake Tower (mid-reservoir), Tecolote Tunnel (6.4 miles), and South Coast Conduit (27 miles). This is a critical lifeline system that must maintain flow 24 hours a day, 7 days a week (24/7). Lake Cachuma was recently impacted by seven consecutive years of record drought, reaching a low of 7.2% reservoir capacity in 2016. Early this year a sequence of storms brought moderate rainfall to the watershed, raising water storage to the current level of 77.5% reservoir capacity (March 25, 2019). As the reservoir continues to recover, COMB is planning for the next drought. Without sufficient rainfall occurring during the next two winters, the ability to gravity feed the Intake Tower could be precluded as early as fall 2021. This could occur as the lake level drops below the inlet gates located on the Intake Tower. Previous dry periods and diminishing lake levels have required an Emergency Pumping Facility (EPF) to be installed at Lake Cachuma on three occasions: in 1957 to 1958, 1990 to 1991 and 2014 to 2017. The previous installations in 1990 to 1991 and 2014 to 2017 were temporary facilities with a floating pipeline and a floating pump station to convey water to the Intake Tower. This grant application is for a more permanent solution, the Lake Cachuma Emergency Pumping Facility – Secured Pipeline Project. tĂƚĞƌ ^ƵƉƉůLJ: Cachuma Project water and SWP water are essential water portfolio constituents for South Coast Member Agencies. Under normal conditions, Cachuma Project water plus SWP water constitutes 70% of the supplies to the South Coast. During drought conditions when the Cachuma Project allocation is reduced or unavailable, South Coast communities switch to groundwater and/or banked/purchased water, with banked/purchased water being delivered by the Central Coast Water Authority (CCWA) through the State Water Project (SWP). While dependency on Lake Cachuma is necessarily reduced during a prolonged drought, water being delivered from Northern California still requires transport through Lake Cachuma, and so it remains an integral part of the South Coast delivery system.
