Annual Water Supply & Demand Assessment

The 2026-2027 Annual Water Supply and Demand Assessment predicts a shortage of 4% or 23.2 acre-feet for the reporting period of July 1, 2026, through June 30, 2027. This predicted shortage is an estimate based on preparing for a single dry year. For a full discussion of the metrics, inputs, and analysis, please see the 2026-2027 Annual Water Shortage Assessment Report on the Annual Water Supply and Demand Webpage.

Annual Water Loss Audits

The CCSD is required to complete annual water loss audits, which are then validated by a third party to ensure accurate analysis of all metrics. Water loss is unavoidable in the production and distribution process, but it can be minimized to the best extent possible. Annual audits measure the CCSD's progress in implementing best practices to reduce avoidable losses.
