Feasibility Report and Final Environmental Impact Statement, Wisconsin River at Portage, Wisconsin, Feasibility Study for Flood Control. Main Report

Abstract

This study develops effective and acceptable alternative flood control plans for the Portage area which are consistent with the environmental and historic importance of the area. Included in the general study area are those regions affected by Wisconsin River flooding and backwater flooding in the lower reaches of the Baraboo River and Duck Creek. Specifically, the study area encompasses the city of Portage; the adjacent townships of Lewiston, Caledonia, Pacific, and Fort Winnebago in Columbia County; and the township of Fairfield in Sauk County. Limited study was done on the upper Fox River basin in regard to the impacts of Wisconsin River overflows. On the basis of intensive feasibility-scope investigations and extensive coordination with the public, it is recommended that the Corps of Engineers be the implementing agency for a local protection levee and floodwall plan at Portage. This plan was identified as the most economically feasible plan to construct. The Portage Lock, a historic landmark, would be incorporated to maintain the historic importance and character of the area. (Author)
