The purpose of this study is to define 'critical period' in conjunction with reservoir design and operation, and then to analyze the usefulness of the concept in the evaluation of deficiencies of water for project planning purposes. Streamflow records from a number of rivers in the United States are analyzed, and certain defined characteristics of their various critical periods are derived. These characteristics are shown to be functions of both the active storage and the degree of variation in annual streamflow. A study is made of the significance of the critical periods and their associated droughts respecting their use for design purposes. (Author)
