Large organizations deliver 80 percent of off-farm irrigation water

This is a trio of stacked bar charts showing water delivery organizations by size and scope in 2019, broken by small, medium and large organizations.

Irrigation delivery organizations, such as irrigation districts, ditch companies, mutuals and acequias, provide water to farms and ranches and can vary in size. The USDA 2019 Survey of Irrigation Organizations collected data about them in the 24 States where these organizations are most common. Analysis of the survey data indicated that most irrigation organizations are small or medium in scale based on the number of agricultural acres they serve. An estimated 44 percent serve fewer than 1,000 irrigable acres, and 40 percent serve between 1,000 and 10,000 acres. However, most land and off-farm irrigation water are supplied by large delivery organizations, which serve more than 10,000 acres. While they represent only 16 percent of organizations, they serve 78 percent of irrigated acres with off-farm water and deliver 80 percent of off-farm water. This chart appears in the ERS report Irrigation Organizations: Drought Planning and Response, release January 2022.
