The 2018 National Inventory of Dams (NID) is now available at http://nid.usace.army.mil. All charts, queries and maps reflect the most current NID database. The NID was populated using the 116th Congressional District information. State and federal dam regulators provided their data from May to November 2018 for inclusion in the 2018 database. Please be aware that inspection and EAP dates reflect 2018 data, so any inspections or updates since then will not be reflected in the current NID. Please contact the respective state or federal regulatory authority for the most up-to-date information.
Major changes to the 2018 NID allow users to download or export certain NID data and to view the hazard potential classification. State or federal agencies may restrict access to information on dams within their jurisdiction, in some cases. For information not published in the NID, USACE recommends consulting the agency exercising responsibility over the dam. Also, it is important to note the hazard potential classification, as published in the NID, does not reflect the condition of a dam. That information can be found in the condition assessment, which is available to approved government users.
