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 will end the irrigation season to it's 5,800 users on October 6th, 2020, and will close all headgates on the Boise River October 7th, 2020 stopping all water through it's canals.
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 tell 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.
Ordering water properly is imperative to the day-to-day operations of the District. Our personnel place water orders every day with Water District water managers. If we don't know you need water, we won't order it put into the system for you. If you take water you haven't ordered, you are taking someone else's water.
Likewise, not ordering your water off can cause downstream flooding and is not an efficient use of water. Do not allow your water to waste while being unused, as this shortens the irrigation season for everyone. Best management practices observed by everyone will ensure a more abundant supply in the reservoirs and lengthen the irrigation season.
Please order your water on and off accurately through your ditchrider directly. Your ditchrider's contact information can be obtained on the Contact page. The office can tell you who your ditchrider is if you don't know, but the office does not take water orders.
If you have questions, please call Pioneer’s office at 208-459-3617.
