The structure to be constructed south of the diversion inlet control structure along Cass County Highway 17 at an elevation lower than the east/west portion of the dam. This portion of the dam would act as an emergency spillway for extreme events that exceed the 0.2-percent chance flood (i.e., 500-year flood) event design capacity of the Project. An overflow embankment structure would be included as part of the Northern Alignment Alternative as well. Design plans were not available during the development of the EIS, therefore not all direct and indirect impacts have been evaluated at this time.
