The optimal release policy for a large and shallow lake subject to the double uncertainty of average monthly hydrologic input and instantaneous wind‐induced water rise is calculated. The case of Lake Balaton in Hungary is used to illustrate the methodology. Loss functions are obtained for each lakeshore section; losses due to unfavorable (high or low) water level are given on a monthly basis, and dynamic losses due to waves and wind tides are calculated by using an event‐based model. A stochastic dynamic programing formulation yields an optimum release policy whose sensitivity to loss functions and discount factor is examined.
