Description Water temperature is one of the most important factors determining the health of fish and other aquatic organisms. If water temperatures warm beyond a critical threshold, particularly during the sensitive life stages of fish, survival can markedly decrease. In 1996, the State of Oregon adopted a revised maximum water temperature standard of 17.8 C (degrees Celsius) (64 F [degrees Fahrenheit]) for most waterways, including the Tualatin River in northwestern Oregon. To assess water temperature conditions in the Tualatin River, a recent cooperative study between the U.S. Geological Survey and the Unified Sewerage Agency ofWashington County, Oregon, used two dynamic-flow heat-transport models, DAFLOWBLTM (river mile [RM] 63.9-RM 38.4) and CEQUAL-W2 (RM 3 8.4-RM 3.4). After the models were calibrated with data collected during the 1994 low-flow season, they were used to simulate various hypothetical water-management scenarios. Results from the first 10 scenarios were published in an earl
