Sycamore Spreading Works Expansion Project

Sycamore Spreading Works Expansion Project

The Arvin-Edison Water Storage District (AEWSD or District) proposes to expand the existing 569-acre Sycamore Spreading Works (the Project) located on the alluvial fan of Sycamore Creek. The Project will involve constructing approximately an additional 90 acres of spreading/recharge ponds. The area in which the expansion would be constructed is adjacent to existing ponds of the spreading works and would be hydraulically connected to them by additional control structures. Diversion of water into the spreading ponds is accomplished by gravity flow from the Arvin-Edison Canal through structures equipped with manually operated slide gates. With the spreading works and associated well fields, water stored underground may later be recovered when required through existing District wells and pipelines. Annually, additional water recovered from the existing wells is projected to average approximately 2,000 acre-feet, with a maximum one-year recovery of 11,600 acre-feet. The amount of water recovered (extractions) will be less than the amount of water recharged. Thus there is a net positive benefit to the groundwater aquifer from the Project. The District developed a 50-year analysis using DWR methodology to forecast groundwtaer babanking operations and activities. The District is committed to balancing recharge and well recovery volumes, with more water recharged than recovered over time in order to help mitigate any groundwater overdraft occurring within the District. With the Project, both groundwater levels and groundwater quality are predicted to improve. The District would recover water from existing wells during periods when irrigation demands cannot be met from limited surface water supplies.
