Malheur Siphon

   The Malheur Siphon is a landmark that has been in our valley for 80 years. It has stood the test of time, but not without taking a toll. We will address many concerns in the future, but in the short term, the location of the biggest area of concern is near the Malheur Butte, where large steel legs hold the Siphon in place. These legs have many different issues that are jeopardizing the integrity of the steel pipe and weight that it requires to carry the flow of irrigation water to the north side of the valley.         

    The District has contracted with MWH Americas, an engineering firm from Boise, who has performed an evaluation, structure analysis, and is currently engineering the design of the replacement structures to support the siphon. The District will continue to move forward on the timeline for repairs and pursue funding options that are available. The District estimates this will be a multiple year project.

    The Twilight gravity flow pipeline project is being finished and will be ready this spring for growers in the Sunset Valley area.




Vista View Pipeline 

    At the end of this water season, the start of the Vista View gravity flow pipeline project located near Morgan and Clark Avenue will start.
