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.





  **** The District will begin the process of priming the irrigation system Monday, March 20th.  If you pump from the canal DO NOT begin pumping until all the debris and muck has been flushed out of the canal.  This process will take several days.  The District will not have anyone available to help you get unclogged until all services have been turned on throughout the District.  This can take up to two weeks or longer. Thank you for your patience while we are preparing for water season.

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
