Abstract: A methodology for assessing the effects of alternative flow release scenarios on both aquatic habitat and on energy production was utilized during instream flow studies at a 72-MW hydroelectric project in the northeastern U.S. Effects on habitat were evaluated using a habitat time series analysis based on hourly discharge data from the project. The energy ramifications of the alternative flow scenarios were assessed using a computer program in which daily energy production is divided into four priority periods, and the increase or decrease in energy production between priority periods as a result of the alternative flow releases is calculated. This method can be a useful planning tool for screening alternative flow regimes prior to negotiating flow releases from a hydroelectric project.
