The potential exists for a disastrous flood at Portage, Wisconsin, due to the topography of the area and previous attempts to modify the flood flow characteristics of the Wisconsin River. Levees built by local interests do not meet design standards of the Corps of Engineers or Wisconsin Dept of Natural Resources. This plan of study provides a framework for development of alternative flood control plans. Major items included are: a general profile of the study area, identification of flooding and related problems and possible alternatives to solve these problems, an outline and general description of the investigations to be conducted during the study, and a description of the public involvement program.
