Abstract: The National Inventory of Dams database contains information on 79,777 dams throughout the United States and its territories. The National Inventory of Dams began in 1972 with the National Dam Inspection Act and continues to be updated with the Water Resources Development Act of 1986 and 1996. The Corps of Engineers is authorized to maintain and publish the inventory. Significant changes have been made to the inventory data over the last 20 years, including the addition of new dam records and removal of breached dams, and duplicate dam records. The data is submitted from all 50 states, US territories and 16 federal agencies. The NID includes all high and significant hazard potential classification dams. Low hazard potential dams must exceed 25 feet in height and15 acre-feet in storage or exceed 50 acre-feet in storage and 6 feet in height. This inclusion criteria is applied to all dams submitted to the NID. The Corps calculates two fields, NID height and NID storage, which are the maximum values in their multiple respective fields and these values are used in the inclusion criteria process. Since the last update in 2001, one new field, submit_date, has been added. This field represents the date the agency submitted the data to the Corps of Engineers. All 109th congressional information contained in the NID was populated based on a GIS query of the dam coordinates. If a dam has no coordinates (noted as -999.999, -999.999 in the database), no congressional information is associated with that dam.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
The National Inventory of Dams database contains
information on 79,777 dams throughout the United States
and its territories.  The National Inventory of Dams
began in 1972 with the National Dam Inspection Act and
continues to be updated with the Water Resources
Development Act of 1986 and 1996.  The Corps of
Engineers is authorized to maintain and publish the
inventory.  Significant changes have been made to the
inventory data over the last 20 years, including the
addition of new dam records and removal of breached
dams, and duplicate dam records.   The data is submitted
from all 50 states, US territories and 16 federal agencies.
The NID includes all high and significant hazard potential
classification dams.  Low hazard potential dams must
exceed 25 feet in height and15 acre-feet in storage or
exceed 50 acre-feet in storage and 6 feet in height.   This
inclusion criteria is applied to all dams submitted to the
NID.  The Corps calculates two fields, NID height and NID
storage, which are the maximum values in their
multiple respective fields and these values are used in the
inclusion criteria process.  Since the last update in 2001,
one new field, submit_date, has been added.  This field
represents the date the agency submitted the data to the
Corps of Engineers.  All 109th congressional information
contained in the NID was populated based on a GIS
query of the dam coordinates.  If a dam has no
coordinates (noted as -999.999, -999.999 in the database),
no congressional information is associated with that dam.

Purpose:
The 2005 National Inventory of Dams is provided as
an update to the 2001 National Inventory of Dams.  The
database record for a dam in the National Inventory
consists of data from participating agencies submitted in
accordance with the update methodology, the name of the
agency providing data and the date the data was
submitted.  About 20,000 records were merged from
multiple data sources.

Overview description:
Entity and attribute overview:
The National Inventory of Dams database contains
over 60 data fields.  Definitions for each field can be found
in the NID data dictionary,
//crunch.tec.army.mil/nid/webpages/niddatadictiona
ry.html.  There is only one new data field named
"submit_date" which represents the date the agency
submitted the data to the Corps. The data for that agency
is only valid until that date.  Any construction or
modification to dams after this date, will not be included in
the NID.
