This map shows the extent of the would-be reservoir on the Meramec River in Missouri if theCorps of Engineers had completed the dam at Sullivan.  Construction had already started when the dam was rejected in a non-binding referendum in the surrounding counties in 1978.  Congress defunded the project, and it was formally deauthorized in 1981.  This map is based on a maximum pool elevation of 709 ft (216 m) and 30-arcsecond SRTM elevation data.  Projected in the UTM Zone 15 North coordinate system.
