Watermasters

Each active water district in Idaho has a watermaster who oversees water distribution within the district. Watermasters in Idaho are appointed by the director of IDWR 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. Daily water distribution, record keeping, measurement and general district management are the primary duties of each watermaster.
