Geospatial data sets and hydraulic models for selected streams in Stark County, Ohio Geospatial data sets and hydraulic models for selected streams in Stark County, Ohio
Digital flood-inundation maps for selected streams in Stark County were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District and the Stark County Commissioners as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and...
