Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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. </SPAN></P><P><SPAN>Dam outlines were delineated manually using imagery, elevation, dam project diagrams, and other sources. They are approximate and only intended to indicate general size, location, and orientation. The Dam_polygons layer has a companion layer, Dams_points. </SPAN></P><DIV><DIV><P><SPAN>Fields:</SPAN></P><P><SPAN>NAME: Commonly used or official dam name</SPAN></P><P><SPAN>POP_NAME: Alternate or popular dam name</SPAN></P><P><SPAN>NID_ID: National Inventory of Dams ID (</SPAN><A href="https://nid.sec.usace.army.mil:443/" STYLE="text-decoration:underline;"><SPAN>https://nid.sec.usace.army.mil/#/)</SPAN></A></P><P><SPAN>DEP_ID: Numeric ID field.
