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.
