Abstract
The Arkansas State Highway Department is constructing Interstate Highway 430 (1-430) across Fourche Creek in southwest Little Rock. The Highway Department requested the U.S. Geological Survey to determine the elevation, the discharge, and the frequency of the flood of April 21, 1974, and the elevation, the discharge, and the backwater for the 50-year flood, and to report on the hydrologic effects of alterations to the proposed bridges and roadway to accommodate the larger of the two floods.
All elevations in this report are given to highway datum, which is mean sea level.
This report was prepared under the provisions of the cooperative agreement between the Arkansas State Highway Commission and the Geological Survey.
