1. A new irrigation project study targets demand similar to CSIP’s The Water Resources Agency is studying a new in-lieu irrigation supply project adjacent to the Castroville Seawater Intrusion Project (CSIP), focused on agricultural pumping in the 180/400-Foot Aquifer Subbasin. Potential supplies under study include wastewater at the regional treatment plant not used by CSIP, agency water rights in Tembladero Slough and other local waterways, the Salinas River Diversion Facility, possible reservoir re-operation and other local sources. Staff said demand in the proposed service area is similar to CSIP’s roughly 20,000 acre-feet in annual deliveries. That is a comparison of demand, not a projected delivery volume for the new project. Initial supply findings were described as somewhat promising, with another update expected in spring 2026.
