The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels, the filling procedures must satisfy safety requirements of the project. Some natural events of uncontrollable magnitude, such as unpredictably large floods of long duration, can radically alter a planned reservoir filling plan. This paper presents the results of an inventory of rate of reservoir filling at 60 dams over 150 ft in height. Some case histories of rapid filling are discussed, together with the project-specific considerations and the actual flow conditions which influenced the operation.
