Settlers Irrigation

Settlers will begin turning water into the canal the second week of April with deliveries the following week.  We will update the website with the official date when it has been determined.  Please contact your HOA or subdivision website for irrigation questions and updates.  Settlers turned water out of the canal on October 6th, 2017.

WATERING SCHEDULES: When reviewing your watering schedule, please adhere to these guidelines unless otherwise noted for your subdivision: The irrigation system is designed for use based on a rotation system. The system is not designed to allow all homeowners to water at the same time. If too many homes irrigate at the same time, especially during the peak use time of 5:00 a.m. – 9:00 a.m., the pump station will produce low pressure and volume and may shut off.

Homeowners are allowed to water only 3 days per week for no more than 2 hours on each of those days. For those who cannot set their timers to "Even" and "Odd" days, assume M, W, F, are "Even" and Tu, Th, Sa are "Odd". Choose 3 days and set your times as indicated on the watering schedule. It is essential to follow your watering schedule in order to avoid low pressure issues.

Settlers Irrigation District began as the Settlers Ditch Company on October 30th, 1884, and now serves thousands of water users in a large part of western Ada County.

The original purpose for the construction of the Settlers canal was to bring irrigation to the prairie and sage brush lands on the south side of the Boise River to entice settlers into the area. The Settlers canal begins on the south side of the Boise River at a point on the head of Government Hay Reservation now known as Ann Morrison Park.

The original locators of the canal and water right were Christian R. Purdum, Adolphus Purdum, and William H. Smith. They made their filing on October 17, 1884, and claimed 50,000 inches of water. By 1891 water flowed through the canal.

Work on the canal was started and stopped between the years of 1884 and 1904 as the boundaries expanded and the name changed from The Settlers Ditch Company to the Lemp Canal to Settlers Canal Company, Ltd. and finally Settlers Irrigation District in 1904. There are now 13,187 acres included in the District.

The canal now measures approximately 20 miles in length with 95 miles of laterals and it conveys approximately 9,322.15 miner's inches of water. Water deliveries for the main canal begin at North Mitchell Street and end approximately one half mile west of Black Cat Road dumping into the Five Mile Drain. Water deliveries for the south side of the Settlers' Canal begin west of Five Mile Road and south of Ustick Road eventually dumping into a Nampa and Meridian Irrigation District drain below Black Cat Road.
