The purpose of the long‐term control strategy is to define retention levels for a multipurpose reservoir that permit maximum storage to be available for flood alleviation subject to shortages in its water supply function occurring with a specified tolerable frequency. A recursive relationship is derived to calculate the probability of no shortage occurring within a chosen interval of time for any given set of retention levels. This relationship is used in conjunction with an iterative search procedure that finds the optimal set of minimum retention levels necessary to meet a given demand with a specified acceptable frequency of failure, and thereby as much storage as possible is allowed for flood alleviation.
