Description: The Maine Dams dataset, maintained by the Maine Department of Environmental Protection (DEP) is a comprehensive spatial and tabular data base of dams, levees, impoundments, and barriers that are in and around Maine’s lakes, streams, and rivers. It includes both current and historical facilities. Spatial and tabular data will be updated on an ongoing basis. The Maine DEP Dams layers were created from various sources, including a historical dams dataset based on the Inventory of Dams on Maine Waterways (1973), the Maine Emergency Management Agency (MEMA) dams datasets, the Maine Stream Habitat Viewer (MSHV) dataset, and others. ID fields were created and maintained in order to cross-reference the DEP dataset with the National Inventory of Dams (NID), MEMA, Federal Energy Regulatory Commission (FERC) Projects. Additional fields have been added to indicate the status (present, removed, breached, etc.), the presence and types of fishways, and the FERC licensing status of dams. Point locations indicate the approximate location of dams, and may contain errors. The Dam_points layer has a companion layer, Dams_polygons which contains manually delineated outlines of dam structures. Fields:NAME: Commonly used or official dam namePOP_NAME: Alternate or popular dam nameNID_ID: National Inventory of Dams ID (https://nid.sec.usace.army.mil/#/)DEP_ID: Numeric ID field. Derived partially from 1973 Inventory of Maine Dams.
