Irrigation Districts Section 43 of the Idaho Code authorizes the formation of Irrigation Districts whenever 50, or a majority, of the owners of lands that can be irrigated from the same or different sources and by the same or different systems of works, want to provide for the irrigation of their land, or when for other reasons they desire to organize the proposed territory into an irrigation District. If you would like to view a list of the Idaho Irrigation Districts, please select Irrigation Districts. There are over 100 water districts in Idaho. More than 70 of these districts are currently active.
Districts vary in both geographical size and number of water users.
The state's largest district, District 01, covers most of the Upper Snake River basin above Milner Dam and includes numerous streams and tributaries with thousands of individual water users. The smaller districts may include only one tributary stream with no more than a half dozen users. Each active water district in Idaho has a watermaster who oversees water distribution within the district. Watermasters in Idaho are considered state employees but are elected and compensated directly by district water users. Proper water distribution under Idaho water law and the appropriation system is the primary goal and responsibility of all Idaho watermasters.
