Description: The Rivers_Streams feature class is a geospatial representation of linear bodies of water (e.g. rivers, streams, artificial paths for tidal waters, shorelines, etc) within Maryland's borders. It is based on the National Hydrography Dataset (NHD, 1:24,000 scale) produced by the United States Geological Survey (USGS). This particular file provides the Maryland use class assigned to each linear body of water as specified in Code of Maryland Regulations (COMAR) 26.08.02.08. The dataset is intended to be used in conjunction with the information found in the regulation. By linking MD stream use classifications with the NHD through the common identifier (COMID) code, the information contained in this dataset can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS) to aid in regulatory decision making. Basing the MD use class dataset upon a national stream dataset like the NHD, facilitates the sharing of geospatial information with other organizations that can be integrated into many different types of applications.

MDE would also like to acknowledge the Chesapeake Bay Program for their Chesapeake Bay polygon segmentation file which was used to help determine designated uses in tidal waters.
