California's Water Problem

TL;DR

California allocates 5x more water than it produces, and agricultural interests have legally captured most of it before cities can claim their share.

Key Points

• 1.Southern California gets nearly zero local rainfall (LA: 12–15 in/year vs NYC's 42–49 in/year) and depends on three massive aqueducts — the LA Aqueduct, Colorado River Aqueduct, and California State Water Project — for 80–88% of its water
• 2.Under "prior appropriation" law, water rights are first-come-first-served, meaning farms and ranches established before cities hold senior rights and get water first during shortages
• 3.A 2014 UC Davis study found California allocates ~370 million acre-feet of water rights per year but only produces ~70 million acre-feet in a good precipitation year — a 5x structural deficit
• 4.Agriculture consumes 80% of California's water but contributes only 2.5% of the state's economy, creating a massive efficiency mismatch between usage and economic output
• 5.The Wonderful Company (owned by the Resnick family), through the controversial 1994 Monterey Amendments, acquired 57% of Kern County's underground water bank (1.5 million acre-feet), giving them more water access than all LA households combined
• 6.The 1994 deal also eliminated the State Water Project's "urban preference rule," which had guaranteed cities water priority during droughts, shifting power further toward private agricultural interests
