The purpose of this report is to present the results of a study made for a 35,000-foot reach of Morgan Creek. The report shows profiles computed for a large flood under existing conditions and for a smaller flood for two assumed conditions of encroachment. Flood-plain management can benefit from this type of information during future expansion of the urban area. This report is a result of a cooperative agreement between the City of Cedar Rapids and the U.S. Geological Survey that provides for the collection and analysis of flood data in, and near, the City of Cedar Rapids.
