Water Quality in Keno Reach of the Klamath River Active
The U.S. Geological Survey, U.S. Bureau of Reclamation, and Watercourse Engineering, Inc. are collaborating to develop knowledge and tools to better manage water quality in the Link-Keno reach of the Klamath River and the Lost River.
The Klamath River from Link River to Keno Dam and Lost River experience poor water-quality conditions on a seasonal basis. The water-quality at sites in these reaches has been classified as “Very Poor” by the Oregon Water Quality Index. These problems led the Oregon Department of Environmental Quality to release nutrient and water temperature Total Maximum Daily Load (TMDL) plans to bring the river into compliance with water-quality standards. A TMDL is a plan for restoring impaired waters that determines the highest amount of a pollutant a water body can receive and still meet standards.
The nutrient TMDL specifies nutrient and BOD5 load reductions for point and nonpoint sources along the Link-Keno reach. For example, it requires greater than 80-percent reductions in total nitrogen, total phosphorus, and BOD5 for the Lost River Diversion Channel and Klamath Straits Drain. Load allocations in the Lost River TMDL represent 50% reductions in dissolved inorganic nitrogen and carbonaceous BOD (CBOD) and require dissolved oxygen increases for the impoundments.
The U.S. Geological Survey, U.S. Bureau of Reclamation, and Watercourse Engineering, Inc. are collaborating to develop knowledge and tools to better manage water quality in the Link-Keno reach of the Klamath River and the Lost River. This collaboration has led to enhanced water quality datasets, understanding of fundamental water quality processes such as algal decay, and settling, the construction and enhancement of CE-QUAL-W2 water quality and hydrodynamic models, as well as model scenarios that provide insight into how future operations could affect water quality.

Filter Total Items: 16Assessment of diel chemical and isotopic techniques to investigate biogeochemical cycles in the upper Klamath River, Oregon, USA
The upper Klamath River experiences a cyanobacterial algal bloom and poor water quality during the summer. Diel chemical and isotopic techniques have been employed in order to investigate the rates of biogeochemical processes. Four diel measurements of field parameters (temperature, pH, dissolved oxygen concentrations, and alkalinity) and stable isotope compositions (dissolved oxygen-??18O and disAuthorsS.R. Poulson, A.B. SullivanKlamath River Water Quality and Acoustic Doppler Current Profiler Data from Link River Dam to Keno Dam, 2007
In 2007, the U.S. Geological Survey, Watercourse Engineering, and the Bureau of Reclamation began a project to construct and calibrate a water quality and hydrodynamic model of the 21-mile reach of the Klamath River from Link River Dam to Keno Dam. To provide a basis for this work, data collection and experimental work were planned for 2007 and 2008. This report documents sampling and analytical mAuthorsAnnett B. Sullivan, Michael L.

Wellman, Jennifer VaughnAn assessment of flow data from Klamath River sites between Link River Dam and Keno Dam, south-central Oregon
Records of diversion and return flows for water years 1961?2004 along a reach of the Klamath River between Link River and Keno Dams in south-central Oregon were evaluated to determine the cause of a water-balance inconsistency in the hydrologic data. The data indicated that the reach was losing flow in the 1960s and 1970s and gaining flow in the 1980s and 1990s. The absolute mean annual net water-AuthorsJohn C. Risley, Glen W. Hess, Bruce J.
