The Oregon Water Resources Department (OWRD) serves the public by practicing and promoting responsible water management. Jeremy Giffin (pictured above) is the OWRD’s Watermaster for Central Oregon and has spent the past 17 years working to ensure long-term sustainability of Oregon’s ecosystems, economy, and quality of life.

DRC: After a long, dry summer, what are water supplies looking like?

Jeremy: The Deschutes and Crooked River basin reservoirs are seasonally low ranging from 21%-67% of capacity. As a result of the very dry conditions through 2013 the natural flows are lower than average and many of the streams in Crook County have gone dry this year.

DRC: We know that flows in the upper section of the Deschutes River tend to be lower in the winter months while flows are being stored in Wickiup and Crane Prairie Reservoirs for summer irrigation. What do you anticipate river levels looking like after such a dry summer?

Jeremy: The flows in the upper Deschutes will start the storage season (typically set mid-October) slightly above the state required minimum of 20 cubic feet per second, as measured at the river gage immediately below Wickiup reservoir. If we have an above average winter with precipitation we could possibly re-assess the situation and increase flows later in the winter if conditions permit.

DRC: How does the OWRD decide the flow level in the Upper Deschutes below Wickiup Reservoir in the winter?

Jeremy: In Oregon, water rights are full filled based on seniority. We manage the flows to ensure that the senior water rights are satisfied first. If we have water in excess of the legal rights we will work with ODFW and other partners to provide flows for ecological needs which tend to be junior.

DRC: We just saw Colorado struggle with massive flooding. Could that kind of thing happen in the Deschutes basin?

Jeremy: Possibly in the Crooked River basin and even to a lesser extent in the drainages of Tumalo Creek, Whychus Creek, Little Deschutes River & Trout Creek. However the mainstems of rivers such as the Deschutes and Metolious are largely spring fed and not as susceptible to large scale flooding like we recently saw in Colorado.
