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.

Pioneer has not yet determined a shut-off date, but it will be posed as soon as we do.

Each property is assigned a ditchrider. If you experience problems with your irrigation, please contact your ditchrider directly. Their phone numbers are located on the Contact page. If you don't know who your ditchrider is, please call the office and we can assist you.

PLEASE NOTE: The office does not schedule service calls or take water orders for ditchriders. You must contact them directly. They are often out on their rides, so if you get their voicemail, please leave them a complete message and they WILL call you back.
