DESCRIPTION
The Jamestown S'Klallam Tribe used this funding to improve salmon habitat by increasing instream flows, (especially during critical low flows), by piping irrigation ditches with proven high losses in the Dungeness watershed WRIA 18, Clallam County. Benefits of piping irrigation ditches include: improved water quality by lowering instream temperatures by increasing flows (reducing diversions); improved water quality by reducing pathways for pollutants to enter the watershed via open irrigation ditches; improved habitat by reduced diversions from the Dungeness. The project benefits all Dungeness River salmon stocks including ESA-listed Dungeness Chinook, summer chum, steelhead and bull trout. All of the piping projects were high priority from the "Sequim-Dungeness Agricultural Water Conservation Plan". The project was sponsored by Dungeness Valley Agricultural Water Users Association and Jamestown S'Klallam Tribe. Due to the fact that some of the labor was conducted by irrigation district/company work crews, significant cost-savings were realized, enabling additional sites for the project (additional piped ditches, equating to additional Dungeness River water conservation).
State dollars were used for contracted labor, materials/equipment/project management, and project success monitoring. The Association and Tribe provided engineering, inspection, some labor and equipment. This project is identical to others completed that have increased irrigation efficiency, resulting in quantifiable amounts of water left instream.
