Abstract: A reservoir operation plan is prepared for a single-purpose flood control reservoir. Real-time precipitation data recorded at the dam is utilized to control the reservoir gate operations. The plan utilizes the precipitation during the past 30 minutes and is adjusted by the water surface elevation in the reservoir. This operation plan allows maximum possible release at the dam without exceeding downstream channel capacities for design inflows to the reservoir of 100-year frequency or less. For floods larger than 100-year flow, downstream channel capacities will be exceeded for a relatively short period of time.
