摘要

The heavy rains that inundated western Wisconsin, and much of the Midwest, during211u001ethe spring and early summer of 1993 heightened local officials' awareness of the 211u001eimportance of maintaining and properly regulating the many dams in the rugged 211u001eunglaciated 'Driftless Area.' The ensuing Federal Disaster Declaration yielded 211u001esubsequent funds for the preparation of a Long-Term Flood Recovery Plan. One of 211u001ethe plan's programs called for an analysis of the dams in western Wisconsin's 211u001e'Driftless Area.' This document summarizes the project's 114 dam safety reports 211u001einvolving 42 dams. The purpose of the reports is to delineate more precise 211u001efloodplain boundaries below the dam in the event of a breach; assess the 211u001estructural integrity of the dam; provide dam operation, inspection, and 211u001emaintenance recommendations; and develop an emergency action plan to minimize the 211u001eloss of property and life in the event of a dam breach. The potential economic 211u001eloss resulting from a dam breach was also determined for each of the 42 dams. 211u001eSuch losses range from $121,000 to $7.1 million. The reports have all undergone a 211u001econformance review by the Wisconsin Department of Natural Resources.
