Pioneer Irrigation District is a non-profit irrigation district providing irrigation water to 34,000+ acres of land in parts of Canyon County and Western Ada County, Idaho.  Established in 1901, Pioneer is proud to be a part of the Treasure Valley's rich agricultural history and we are continually looking for the best ways to manage water needs now and into the future for both agricultural and residential irrigation uses.
