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.

Important News Updates

Water is currently out of Pioneer's system.

Crews are starting winter maintenance activities. Please make sure any items you may have in ditch/canal easements are moved immediately. Pioneer is not responsible for damage to items left in the easement, and property owners may be charged for removal of items left in easements.

Please also note that the off-season is a great time for property owners to perform maintenance along fence lines, etc. Pioneer does not burn or maintain weeds right up against fence lines, in order to avoid damaging fences. Property owners are responsible for that maintenance, as well as trimming any trees/bushes out of the easement.

If you have questions about Pioneer's maintenance activities, or property owner responsibilities along easements, please call Pioneer's office at (208) 459-3617.
