McHaley Pipeline and Irrigation Improvements Project
The McHaley Ditch Pipe and Irrigation Improvements Project provided cost-share funding to design, bid, and construct the McHaley pipe design and riser system for irrigation. This project will combine two diversions (Upper and Lower McHaley) into a single fish friendly diversion located at the Upper McHaley Point of Diversion. The water righted amount for both diversions will be piped from the Upper McHaley down to the Lower McHaley in the new pipeline. A tee was installed with a regulated outlet box on both the Upper and Lower McHaley ditches will be installed in order to regulate the proper amount of water that will be delivered to each respective ditch. There will be pressurized risers installed on the pipeline for the Upper McHaley ditch which will be pressurized by the elevation difference between the inlet box and the risers. The pressurized risers will improve irrigation efficiency and the pipeline will allow spring water to be returned to the John Day River where habitat will be improved.
