This week we are celebrating our longstanding partnership with Marc Thalacker and his 20th anniversary as Manager of the Three Sisters Irrigation District. Marc’s vision, will and determination were instrumental in the achievement of historic change for Whychus Creek and the district. In 1999, when Mid-Columbia Steelhead became ESA listed species, Marc assessed the threat and embraced an aggressive plan to restore Whychus Creek and protect his district. Marc worked closely with his board, patrons and stakeholders to pipe the district’s canal conserving and restoring 14.32 cfs (soon 1.16 more) to Whychus Creek while providing pressurized water to his patrons. The DRC has invested more than $10 million in the district’s canal piping over the past 6 years and the district will be fully piped by next year. As a result, Whychus Creek is one of the few places in Oregon where the state’s minimum streamflows have been achieved. Thank you Marc for our great partnership and wonderful success story.
Upper Deschutes River
The Basin Study Work Group is a basin wide collaborative working to restore flows in critical reaches such as the Upper Deschutes for the past 2 years. This year, the group is identifying the specifics of new water management solutions for the Upper Deschutes Basin. These include water conservation, water marketing, new storage options, and new ways to re-balance water between rivers, farms and cities. Bureau of Reclamation will model these solutions to help us understand how well they meet instream and out of stream needs under different climate change scenarios. This work will be complete spring of 2018. We are looking forward to then making large scale agreements that will guide the sustainable management and use of water moving into the future.
We are moving forward in our partnership with Ochoco Irrigation District to develop the McKay Creek Water Rights Switch. This project would restore natural flow to McKay Creek in exchange for providing landowners irrigation water rights from Ochoco Irrigation District. Increased flows will improve habitat and water quality for summer steelhead and redband trout, and will increase fish access to 37 miles of stream in McKay Creek.
Phase Eight of the Three Sisters Irrigation District Main Canal begins this winter. This phase will pipe another 4,400 feet and protect an additional 1 cfs instream. With the completion of Phase Eight, the project will include 8.27 miles of piped canal yielding 14.32 cubic feet per second (cfs) of conserved water–all of which is protected instream. This increase in streamflows will help meet minimum streamflow targets from April through October to improve conditions for reintroduced steelhead, Chinook salmon, and native redband trout from the diversion to the mouth of Whychus Creek.
Whychus Creek in Sisters has made a huge comeback in the past several years through the collaborative efforts of the Deschutes River Conservancy (streamflow), Three Sisters Irrigation District (TSID – water conservation), the Upper Deschutes Watershed Council (fish passage & habitat) and the Deschutes Land Trust (land conservation).
Long-time Central Oregon residents will remember Whychus Creek running dry in the summer months, severely impacting native fish populations. Since we started flow restoration efforts in Whychus, the creek now almost meets the State’s minimum flow requirement of 33 cubic feet per second (cfs). Increased flows of cool water are going a long way to restore stream conditions that support the successful reintroduction of salmon and steelhead in Whychus Creek.
Much of this restoration work has been achieved through creating a more efficient irrigation system for TSID. By piping their leaking canal system, TSID is able to restore flows to the creek while delivering pressurized water to its farming and ranching patrons, reducing or eliminating their pumping costs.
The fourth phase in TSID’s ongoing initiative to completely pipe its system was recently completed – TSID has now piped over 60% of its 60 miles of canals. This phase of the project piped one mile of the canal, restoring 1.3 cfs to Whychus. That is more than 840,000 gallons of water per day! This winter, a similar project breaks ground bringing TSID even closer to completing their water conservation project and restoring a total of an additional 1.3 cfs to Whychus Creek. This project is funded by the Pelton Fund, National Fish and Wildlife Foundation, The Nature Conservancy, Bureau of Reclamation and the Three Sisters Irrigation District.

In 2011, the Deschutes River Conservancy surpassed the state’s 20 cfs flow target on the upper reach of Whychus Creek, a feat never before achieved on any stream in Oregon. Reaching this goal, established by the Oregon Department of Fish & Wildlife, was successful thanks to the cooperation of private landowners and Three Sisters Irrigation District.
These remarkable accomplishments are only possible when parties of seemingly different interests find common ground and work together. Along these same lines, 2011 saw the start of a landmark agreement between the DRC and North Unit Irrigation District to restore flows in the Crooked River while providing the district significant savings in pumping costs. The project will enhance habitat for reintroduced steelhead and salmon and will assure a better water supply for Central Oregon’s most productive commercial farmers.
It is our partnerships of which we are most proud – partnerships not only to restore streamflows and improve water quality, but also to provide municipal water supply, restore streamside vegetation and fish passage and to conserve critical lands. Together, the DRC and its partners are making historic change in our precious watersheds throughout the Deschutes River Basin. And 2011 was another great year.
