The Deschutes River brings so much to our lives. It inspires our runs, walks and rides. Its powerful waters work hard to bring life to our region, but we can live in Bend for many years without knowing how the devastating fluctuations in flows are affecting our river.
For the past two years, the DRC has been engaged in the Upper Deschutes Basin Study designed to develop strategies to meet long-term water needs for our rivers, irrigators and cities.
Over the last two years, the study team has generated a large body of information on the tools available to do this. The Basin Study Work Group (BSWG), a diverse group of stakeholders, co-manages this study with the Bureau of Reclamation. This summer, the BSWG will develop water management scenarios that package tools to generate and move water around to meet needs. In the fall, the Bureau of Reclamation will run these scenarios through its water resources model to help us understand which scenario best meets needs, and the group will evaluate factors like cost and timeliness. The study will wrap up a year from now and will provide the foundation for a broadly-supported long-term plan that takes care of long-standing river issues and our communities.
Last night, the Coalition for the Deschutes and the Farmer’s Conservation Alliance (FCA) presented to an audience of about 50 people at the downtown branch of the Deschutes Public Library. FCA helped community members understand how modernizing irrigation practices in Central Oregon benefits farmers and local rivers, which ultimately benefits our community. FCA has considerable experience installing fish screens and modernizing irrigation districts in the Hood River area. They are enthusiastic about opportunities to partner with the Deschutes River Conservancy, Coalition for the Deschutes, local irrigation districts and other regional partners to help restore streamflow to the Deschutes River. This program was part of an ongoing series hosted by the Coalition for the Deschutes to raise awareness of the issues facing the Deschutes River. Learn more about these challenges and the collaborative solutions now being developed through the Basin Study Work Group.
We all know that rivers need water. Here, in the Deschutes Basin, we are fortunate to have an abundant supply of water from an extraordinary spring-fed river, but today the use of that water is a topic of intense discussion. The current use of Deschutes River water is based on a system set up over a century ago to provide water for agriculture. Public demands for water have expanded since then to include growing cities, recreation and ecological health. We must now find a way to sustain century-old irrigated agriculture while providing for important new economic uses of water as well.
Every winter, irrigation districts store water in Wickiup, Crane Prairie and Crescent Lake Reservoirs for irrigation during the following summer. This stored water augments natural summer flow in the Deschutes River primarily to support Jefferson County farmers, holders of junior water rights, every year. The stored water also provides important insurance for other local irrigators in years of drought. While this water allocation allowed for the successful establishment of agriculture during the 20th century, it did not fully account for the associated ecological impacts to the river.
In many years, the flows coming out of Wickiup Reservoir decrease by over 98% from summer to winter, from as much as 1,800 cubic feet per second (cfs) in the summer to as low as 20 cfs in the winter. You only need to take a walk along the Deschutes River upstream from Bend after mid-October to see first-hand the effects these reduced flows have on the river’s floodplains, stream banks, vegetation and fish habitat.
Assessments of public opinion in recent years indicate that maintaining a healthy river while meeting the water needs of farmers and cities is now a high priority for Central Oregonians. We need new creative water management strategies to meet this challenge.
In response, basin partners are looking into new ways to meet water needs for rivers, agriculture and communities over the next 50 years. While much progress has been made through aggressive conservation efforts by irrigation districts to restore flows in Whychus Creek, Tumalo Creek, Middle Deschutes, and the Lower Crooked Rivers, progress in the Upper Deschutes lags behind and will require a greater effort. To that effect, a $1.5 million Basin Study is underway to provide needed information on restoration options. The collaborative Basin Study Work Group involves all of the diverse, and sometimes conflicting, water interests in the Deschutes Basin voluntarily working toward a modern water management plan.
The Basin Study coincides with a Habitat Conservation Plan (HCP) started in 2008 by the irrigation districts and City of Prineville to address the impact of water management on fish and wildlife.
In 2014, the U.S. Fish and Wildlife Service listed the Oregon spotted frog as a threatened species under the Federal Endangered Species Act (ESA). A number of factors have contributed to the decline of the species throughout its range over the past 50 years. In the Upper Deschutes Basin, the altered flow regime has been identified as one of those contributing factors. This puts additional pressure on water users and resource planners to find alternatives to the current allocation of Deschutes River water.
Impatient with the timeline of the HCP process, two environmental groups recently filed 60-day notices of intent to sue the Bureau of Reclamation for violation of the ESA with respect to the Oregon spotted frog. In addition, one of the notices named the irrigation districts that manage the seasonal storage of water in the reservoirs. These potential lawsuits cite the need for immediate actions as well as longer-term solutions.
The pending litigation against the two member groups of the Basin Study Work Group places challenges on the collaborative process. Finding the most cost-effective short-term solutions to flow issues while evaluating longer-term, more expensive flow restoration solutions is the core mission of the Basin Study. Possible legal actions have the potential to constrain the open brainstorming that is central to developing creative and collaborative water management solutions.
Despite these challenges, we will continue to work together with our partners to stay the course with collaborative planning under the Basin Study. Ultimately, these efforts will show us the best way to restore a healthy river and meet the needs of the the fish, wildlife and communities that depend upon it.
July was hot; the hottest month on record according to the National Oceanic and Atmospheric Administration (NOAA). Combine that with an unusually warm winter, dismally low snowpack and drought declaration in 90% of Oregon and you get some pretty unhappy conditions for fish and other river dwellers.
Native fish such as trout and salmon thrive in river temperatures below 60°F, but as water warms and oxygen levels decrease, fish become stressed. An increase to 68°F and above can turn a river lethal for most native fish.
Sadly, thousands of fish died around Oregon this summer as a result of the low flows, warm water and increased levels of temperature related diseases. We hope the weather conditions we experienced this summer will give way to more normal patterns, but we do have to acknowledge the likelihood of more droughts in the future.
The good news is that here in the Deschutes Basin, many of our streams are spring fed and don’t tend to get as warm as other streams in Oregon. While flows in the Deschutes River below Bend can approach unhealthy temperatures, colder snow-melt tributaries such as Tumalo and Whychus Creeks help cool flows and preserve a healthier habitat.
With our partners, we are now underway with the Upper Deschutes Basin Study which will design the next generation of water management projects to restore flows in the Deschutes River help modernize century old water management practices that are no longer sustainable for today’s diverse needs.
We all have an interest in maintaining healthy rivers. We are all working together to create a sustainable water plan in the Deschutes Basin for tomorrow and for generations to come. Support this important process by getting informed and sharing information with others.

Whychus Creek will flow this summer, revealing both promise and a challenge.
For nearly 20 years, the DRC has partnered with local water interests to collaboratively restore flows in our rivers and streams. This approach has allowed the partial restoration of critical instream flows.
The flow issues existing in the upper Deschutes Rivers, Crooked River and others are more complex. The next phase of the restoration work will be on a much larger scale and will require basin-wide changes in water management.
Over the past two years, the DRC has helped to lead the Basin Study Work Group (BSWG) which is focused upon the long-term water needs of agriculture, municipalities, wildlife, recreation and other interests in the Upper Deschutes Basin.
On April 7th, the BSWG approved a 2 1/2 year plan to implement the Basin Study. The study will begin this summer. It will assess projected water supply and demand for the basin, risks to water supply resulting from climate change, opportunities to increase efficiencies in existing infrastructure, and strategies to meet future water demands.
We are confident there will be enough water for all needs of the basin provided that we’re willing to manage water differently.
