Welcome to Columbia Irrigation

Columbia Irrigation District’s office is open Monday – Friday from 7:30 am – 4:00 pm. The office phone number is (509) 586-6118. During water season the District is available for emergencies 24 hours a day by calling (509) 586-6118.

The system begins at Wanawish Dam where water is diverted from the Yakima River into the main canal.
The CID system consists primarily of open canals, both lined and unlined, which total approximately 41 miles in length.  Some CID lateral pipelines, mostly gravity flow, also exist to distribute water from the canals.  The CID operates and maintains 50 Local Improvement Districts (LIDs) which provide  irrigation water to each individual parcel.


We will be closing the Headgates on October 15, 2015

Columbia Irrigation District is beginning to feel the effects of the drought due to the low water levels in the Yakima River. Effective immediately, CID is implementing an odd/even watering schedule. Individuals with an even numbered address can water on all even numbered calendar dates and those with odd numbered address can water on all uneven calendar dates. Water users should not all water during peak watering periods to prevent low pressure problems.

CID appreciates your cooperation during this difficult irrigation season. Working together will help us maintain our water supply which is important to all water users. The District asks that if your watering day falls on a Sunday to PLEASE water on Sunday. Lack of watering will cause too much water in the canals. Canal levels will have to be lowered causing a shortage of water on the following Monday.

CID has not experienced a drought where water supply has been this short so early in the season. It is hard to predict what the supply will be. Working together and following an odd/even schedule will help prolong our supply.

Tips to think about before calling the District if you think you are having a problem:

No water Check your valve – make sure it is open. (all the way)
Low pressure If you’re using a hose – make sure it is not plugged
  Clean your filter
