While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of existing dams either for increased storage capacity or for improved safety. This paper presents a general discussion of the factors to be considered in designing raises to existing dams for increased storage. Case histories outlining some of the issues addressed in designing raises and planned raises to dams are also presented.
