A general algorithm developed for stochastic optimization of multireservoir systems is used to determine optimal operational policies for five of the major reservoirs of the Parambikulam‐Aliyar irrigation and power project in India. A closed‐loop suboptimal policy was determined for the stochastic inflow, deterministic demand problem, subject to storage and cumulative release constraints imposed by an interstate water‐sharing agreement. The closed‐loop policies were further used to determine optimal rule curves for the major reservoirs. A comparison of the simulated optimal policies and the past performance of the project demonstrates the utility of the derived policies determined with the proposed algorithm.
