This paper reviews some common flashboard methods used in the northeastern part of the U.S., and discusses the advantages and disadvantages of each type. The inflatable rubber dam is presented as a relatively unique flashboard alternative. The operational considerations, construction details, and performance characteristics of the rubber dam are discussed, based upon the authors' experience on one of the first installations of a rubber dam as a flashboard replacement at a hydroelectric plant in the United States. Various considerations affecting the selection of the alternate methods are presented including an order of magnitude price comparison.
