Chesapeake Bay watersheds. The dataset contains locations and attributes of HUC-11 watersheds, created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies. The USGS presents a detailed explanation of HUCs at http://water.usgs.gov/gis/huc.html. HUC-11 boundaries are compiled by each state. The export files of HUC-11 at the state level were provided by each respective state and are unmodified. HUC-11 boundaries for Delaware are not yet available. Also, a small portion of the Chesapeake Basin in NY State has not yet been completed. All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters. METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.
