This dataset contains the State of Florida subset of the 2018 National Inventory of Dams (NID). The NID is a congressionally authorized database, which documents dams in the U.S. and its territories. The NID is maintained and published by USACE, in cooperation with the Association of State Dam Safety Officials (ASDSO), the states and territories, and federal dam-regulating agencies. The database contains information about the dam s location, size, purpose, type, last inspection, regulatory facts, and other technical data. The information contained in the NID is updated approximately every two years. 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. USACE manages the NID but does not own most of the dams in the NID. Operation, maintenance, and repair of these dams is the responsibility of each dam owner. Please contact the respective state or federal regulatory authority for the most up-to-date information. This layer is an update to the FGDL layer USACE_DAMS_2010.
The goal of the NID is to include all dams in the U.S. that meet these criteria, yet in reality, is limited to information that can be gathered and properly interpreted with the given funding. The Inventory initially consisted of approximately 45,000 dams, which were gathered from extensive record searches and some feature extraction from aerial imagery. Since continued and methodical updates have been conducted, data collection has been focused on the most reliable data sources, which are the various federal and state government dam construction and regulation offices.
Congress first authorized the US Army Corps of Engineers to inventory
dams in the United States with the National Dam Inspection Act
(Public Law 92-367) of 1972. The NID was first published in 1975,
with a few updates as resources permitted over the next ten years. The
Water Resources Development Act of 1986 (P.L. 99-662) authorized
the Corps to maintain and periodically publish an updated NID, with
re-authorization and a dedicated funding source provided under the
Water Resources Development Act of 1996 (P.L. 104-3). The Corps
also began close collaboration with the Federal Emergency Management
Agency (FEMA) and state regulatory offices to obtain more accurate and
complete information. The National Dam Safety and Security Act of 2002
(P.L. 107-310) reauthorized the National Dam Safety Program and included
the maintenance and update of the NID by the Corps of Engineers. The
most recent Dam Safety Act of 2006 reauthorized the maintenance and
update of the NID.
The NID consists of dams meeting at least one of the following criteria;
1) High hazard classification - loss of one human life is likely if the dam fails,
2) Significant hazard classification - possible loss of human life and likely
significant property or environmental destruction,
3) Equal or exceed 25 feet in height and exceed 15 acre-feet in storage,
4) Equal or exceed 50 acre-feet storage and exceed 6 feet in height.

Spatial and Attribute Information
GeoPlan Center Process Steps: GeoPlan downloaded the Florida subset of the National Inventory of Dams (NID) from the following U.S. Army Corps of Engineers (USACE) website on November 15th, 2019. https://nid.sec.usace.army.mil The State of Florida subset excel table (FL_U.xlsx) was available for download from the Downloads (Public) tab. https://nid.sec.usace.army.mil/ords/f?p=105:19:15377754200545::NO::: The table was converted to a CSV file format and imported into a file geodatabase. The "add XY data" tool was then used to create a spatial layer from the XY coordinates provided in the database using the NAD 83 geographic coordinate system. Please Note: The original table downloaded contained 1110 records, however, 1 record contained no Latitude/Longitude information. This layer was exported as a shapefile and projected to FGDL Albers. The following tasks were undertaken once the shapefile was projected. - Uppercased all records. - Renamed several fields that were truncated during the conversion to shapefile process. - Added and calculated the PRIMARY_PU field. - Added and calculated the MGRS and GOOGLEMAP fields. - A DESCRIPT field was added based on Dam Name and NID ID. - A FGDLAQDATE field was added based on date of download. - Updated Metadata based off of information found in the Help tab of the Website.

This field is used as the unique identifier for each dam record. The first two characters of the identity are the state two-letter abbreviation, based on the location of the dam. Typically, the last five characters of the identity are a unique number (AB#####); although States are allowed to use alphanumeric combinations in these last five characters. For saddle dams or dikes, the NID ID is the same as the main dam. See saddle dam definition in Number Separate Structures Field (listed below).

River or Stream (Alphanumeric) The River or Stream designation may be entered in one of two ways. For the convenience of some organizations, an alternative field entry is provided which is consistent with the tributary and offstream designations used in the 1995-96 NID. If the alternative form is used, the NID Data Team will convert it to the standard form prior to inclusion in the national inventory. River or Stream Standard Entry: The official name of the river or stream on which the dam is built. If the stream is unnamed, identify it as a tributary to a named river, e.g., Snake-TR. If the dam is located offstream, enter the name of the river or stream plus -OS , e.g., Snake-OS. River or Stream Alternative Entry: The official name of the river or stream on which the dam is built. If the stream is unnamed, identify it as a tributary to a named river, e.g., TR-Snake. If the darn is located offstream, enter the name of the river or stream plus the word, OFFSTREAM, e.g., Snake OFFSTREAM.

For example, if multiple individuals own one dam, it will list P for private dam ownership. Some examples of owner types. Local Government should have taxing authority or is supported by taxes. A Lake District is supported by taxes and considered Local Government. A lake association is supported by association dues and would not be a Local Government owner type but rather Private owner type.

HIGH HAZARD POTENTIAL Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Producer defined
SIGNIFICANT HAZARD POTENTIAL Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be located in areas with population and significant infrastructure.
Producer defined
UNDETERMINED HAZARD POTENTIAL Dams for which a downstream hazard potential, as defined in 1-3 above, has not been designated or is not provided. Note that dams with a code U will be considered for NID inclusion the same as a dam with low hazard potential. If included in the NID, the undetermined classification will be used in publication.

The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
