Research into the temperature effects of operation of the Salmon River Reservoir system of the Niagara Mohawk Power Company was conducted as part of a multi-agency effort to characterize the influences on riverine habitat of power plant operation. Several reports are being prepared to address various parts of the work that has been accomplished. Appendix 1 contains a list of those reports and the reporting entities. The goals of this portion of the research were to determine the magnitude of temperature effects due to power plant operation, and develop methods to predict water temperature in the river under both steady and unsteady flow conditions that are induced by the project operation.
