Abstract:

To support the development of Total Maximum Daily Load (TMDL) programs for the Klamath River in south-central Oregon and northern California, flow and water-quality models were developed by Tetra Tech for the U.S. Environmental Protection Agency, the Oregon Department of Environmental Quality (ODEQ), and the California North Coast Regional Water Quality Control Board. The EFDC model was used to simulate conditions in the Klamath River estuary, the RMA-2 and RMA-11 models were used to simulate most riverine reaches, and the CE-QUAL-W2 model was used to simulate the reservoir reaches. The U.S. Geological Survey (USGS) was asked to review only the most upstream of these models of the Klamath River, from its source at Upper Klamath Lake (Link River Dam) through its first pooled reach ending at Keno Dam.

The model developers have constructed streamflow and water-quality models to simulate a river reach that has highly complex water-quality processes that are not yet fully understood, and the models have great potential to help managers and regulators better understand the system. Certain errors identified in this review, however, need to be addressed before these models can be confidently used to predict temperature or water quality in the Link River Dam to Keno Dam reach of the Klamath River.
