Purpose and scope: This report has been prepared to document these significant floods for future hydraulic and hydrological planning; to provide streamflow information required for orderly development of river basins where the hazard of extreme flooding exists; and to further the general hydrologic knowledge available for Missouri rivers and streams. Streamflow data in the report include peak stages and discharges, flood hydrographs, flood-crest profiles, flood volumes, and flood-frequency information. Descriptions of the storm and of the damages resulting from these floods are given.
