About this figure The gallons shown are irrigation water applied to grow oats in California, divided by the servings the 2022 harvest produced. Applied water per acre comes from the DWR California Water Plan estimate for the crop category (grain); harvested acres and production come from the 2022 county agricultural commissioners' reports; the serving size comes from USDA. The result is a production-weighted statewide average of applied water only; rainfall is excluded.
