Objective and Scope – The objective of this project is to produce a library of flood-inundation maps (FIMs) at half-foot increments of elevation that would span 245 to 250 feet (North American Vertical Datum of 1988; NAVD 88) or the range in elevation from the year-round average water level to a water level that exceeds the 2017 peak (by almost one foot). FIMs would be divided into shoreline segments extending approximately half-way to the adjacent lake gages and would be tied to the water-surface elevation as recorded by the lake gage located mid-way within a given segment.
Relevance and Benefits – This project will support the USGS Mission Areas of Water and Natural Hazards and will meet the USGS goals of (1) providing water-resources and hazards information that will be used by multiple parties (Federal and State) for planning and operational purposes and will contribute to protection of life and property, and (2) contributing data to national data bases that will be used to advance the understanding of regional and temporal variations in hydrologic conditions. Project data will also be used to support the ongoing efforts under Annex 4 of the Great Lakes Water Quality Agreement (GLWQA).
