New Cook County Data: Rivers, Streams, and Lakes

Two new Cook County GIS Open Datasets provide information on the bodies of water in Cook County:

  • Lakes and Rivers shows the location and shape of flowing water features greater than five feet in width and major standing water bodies as polygon data
  • Rivers and Streams represents, as a single line, the interpreted midline of flowing water features. Both of these datasets are developed from aerial photography. These are spatial datasets and can be exported as Shapefile or KML
