Abstract

The State of Wisconsin, as a result of recent legislation, is establishing new, and upgrading old, minimum standards for flood-plain regulation. These standards require evaluations of the flood potential of many streams in Wisconsin.

This report provides an evaluation of flood potential for the Yahara River in the 13-mile low-water channel reach from the dam at the outlet of Lake Kegonsa downstream to the county line. Prepared by the U.S. Geological Survey in cooperation with the Dane County Regional Planning Commission and the Wisconsin Department of Natural Resources, this flood-inundation study gives the computed water-surface elevations and defines the areal limits of inundation for the regional flood.

The regional flood is defined by the Wisconsin Department of Natural Resources as a flood having an average frequency of occurrence of-once in 100 years and "which is representative of large floods known to have occurred generally in Wisconsin and reasonably characteristics of what can be expected to occur on a particular stream."
