The objective of this project is to improve habitat by increasing flows in the Lower Wenatchee by 15 cubic-feet per second (CFS). This project will initiate and implement the primary phase of the Pioneer Water Users Association project in the lower 7.5 miles of the Wenatchee River. This project will create infrastructure improvements for the Pioneer Water Users Association (PWUA) who operate and maintain the Gunn Ditch, which supplies water for agricultural and residential irrigation to shareholders. The project has several components that will address limiting factors in the Wenatchee and is part of the Upper Columbia Salmon Recovery Board implementation schedule. By initiating this project, other biologically productive restoration activities can also be implemented, including habitat improvements, diversion removal, and possible side channel reconnection.
This project has two key elements: 1) The project will replace the PWUA current conveyance system, a gravity fed open ditch, with a new enclosed pressurized system and 2) change the PWUA point of diversion from the flow limited Wenatchee River to the Columbia River. This project would put approximately 15 cfs of the historically diverted water back into the lower 7.5 miles of the Wenatchee River, benefiting habitat for fish, particularly during low flows. The water will be permanently protected as an in-stream flow right through Washington States Trust Water Rights Program (TWRP).
