Source: California Department of Water Resources, as filed by each utility. States differ in what they publish, so these pages differ in what they can show: DWR publishes component volumes and each utility's own water rates, so every figure here carries a dollar amount. It does not flag which components it supplied a default for, so no measured share is derivable. Report a correction.
What the state requires, and of whom: The California water loss audit: who files, and when.
