Best operation policies, linear and nonlinear, were developed for a small reservoir in which storm runoff water might be augmented by pumping water from another source. These policies were aimed at a full reservoir at the beginning of the yearly irrigation season and, indirectly, utilized more efficiently the existing neighboring pumping installations, which are usually idle in winter. The operating policies are expressed as time‐dependent functions indicating the level of the reservoir which would ensure its being full at the end of the rainy season with a given probability. When these policies were tested with a synthetic hydrologic series of 45 years, it appeared that the cost of operating the reservoir was inversely proportional to the daily amount of water pumped into it from external sources.
