| Description: | Technical Report Abstract: This study was conducted to determine the effect that the proposedMarysville Lake pump-storage hydropower (2250-mw power plant) project would have on downstream water temperatures. A one-dimensional numerical model was used for simulation and prediction of temperatures within and downstream of Marysville Lake. Two physical hydraulic models were used for study and description of the hydrodynamic response of the project. Information from the physical models was necessary to determine coefficients used by algorithms within the mathematical model. The mathematical model allowed simulation of the heat exchange characteristics so the thermal regimes within and downstream of the lake could be determined for various hydrologic and meteorologic conditions and various pumped-storage hydropower operations. Results of the study indicate that the temperatures should be within the objective band desired downstream during years with average or wetter than average hydrologic conditions. The study indicated that with the ultimate 2250-mw power plant fall temperature objectives would be exceeded by a maximum of 3°C for a 45-day period during much drier than average years. With the initial installed capacity of 1350 mw, fall temperature objectives could be met under all conditions studied. |
