A model was developed to simulate water levels at three locations on the Columbia River between Priest Rapids Dam River Mile 396.1 (River Kilometer 639.0) and River Mile 361.50 (River Kilometer 581.7). The model was calibrated and verified over a range of flows. The results of calibration and verification indicate that the model, with reasonable accuracy, simulates stages to within +-0.08 m (+- 0.25 ft) and surface wave timing to within +-20 min. The model can be used by researchers, river system managers, planners, and decision makers as a tool to predict fluctuating water levels at locations downstream of dams. Data produced by the model can be used to evaluate and quantify possible impacts on aquatic organisms, water supply, navigation, irrigation, recreation, and additional hydropower enhancement. Although the results of this model calibrationand the model simulations presented are site-specific, the methodology is generic. Therefore, the model can be adapted to reflect dam discharges and resulting river flows at other river systems affected by water-level fluctuations.
