What does this data set describe?

Title:

fox-dams

Abstract:

This shape file shows the location of dams in the Fox River and contains information associated with the dams. Latitude and longitude information for the dams was initially gathered from websites; 1) Dams and obstructions in the Chicago area, http://pages.ripco.net/~jwn/dam.html, accessed on 07/21/2003. 2) Mapquest, http://www.mapquest.com/maps, accessed on 07/21/2003. The locations of dams were verified and established using a script (Lon/Lat Readout in Projection ArcMap written by Trent Hare - USGS, http://arcscripts.esri.com/details.asp?dbid=12841, accessed on 07/23) and the digital ortho quarter quadrangles, 1:13k scales. The rests of attribute information were gathered from "Victor J. Santucci, Jr. and Stephen R. Gephard. April 2003. Fox River Fish Passage Feasibility Study - Final Report to Illinois Department of Natural Resources. Max McGraw Wildlife Foundation. P.O. Box 9. Dundee, Illinois 60118". See "Attributes" for the field definitions in this shape file.
