Description:

Abstract:

This map layer portrays major dams of Florida. The map layer was created by extracting dams 50 feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more, from the 79,777 dams in the U.S. Army Corps of Engineers National Inventory of Dams. This is an update to the mjdams layer.

Purpose:

These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

Supplemental_Information:

In the online National Atlas of the United States Map Maker, at scales smaller than 1:4,850,000 the data is thinned for display purposes. For scales between 1: 4,850,000 and 1:22,000,000, dams are only shown if they have a height of 500 feet or more, or a normal storage capacity of 50,000 acre-feet or more, or a maximum storage capacity of 250,000 acre-feet or more (1280 dams). At scales smaller than 1:22,000,000, dams are only shown if they have a height of 5000 feet or more, or a normal storage capacity of 500,000 acre-feet or more, or a maximum storage capacity of 2,500,000 acre-feet or more (290 dams).
The National Inventory of Dams (NID) is a collection of information about dams in the United States and its territories, produced by the U.S. Army Corps of Engineers (USACE). The USACE works closely with the Association of State Dam Safety Officials (ASDSO), the Federal Emergency Management Agency, and other State and Federal agencies to update and publish the NID. The National Inventory of Dams contains more than 79,000 dams, provided voluntarily by a wide variety of agencies. This information is used to track information on the country's water control infrastructure and to allocate Federal resources for dam safety programs.

Dam Safety Act of 1972 (P.L. 92-367) and Dam Safety Act of 1986 (P.L. 99-662): Any artificial barrier, including appurtenant works, which impounds or diverts water, and which (1) is twenty-five feet or more in height from the natural bed of the stream or watercourse measured at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier, if it is not across a stream channel or watercourse, to the maximum water storage elevation or (2) has an impounding capacity at maximum water storage elevation of fifty acre-feet or more. This Act does not apply to any such barrier which is not in excess of six feet in height, regardless of storage capacity or which has a storage capacity at maximum water storage elevation not in excess of fifteen acre-feet, regardless of height, unless such barrier, due to its location or other physical characteristic, is likely to pose a significant threat to human life or property in the event of its failure.

Process_Step:

Process_Description:

The full National Inventory of Dams (NID) was downloaded from the NID web site in shapefile format and loaded into ArcView. Using an ArcView query, major dams were selected and placed in a new shapefile. Major dams were defined as dams with a height of 50 feet or more, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more. (The International Committee on Large Dams considers dams over 50 feet to be large dams. The USGS Water Resources Division considers large reservoirs to be those with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more.)
One dam in Guam and one dam in the Trust Territories were deleted. Eighty-nine dams without valid latitude/longitude coordinates were also deleted.
Because the text fields contained entries in a mix of formats, some in all capitals and some in capitals and lower-case, all text entries were changed to all capitals.
Some dams were missing county attribute values. The appropriate values were determined by comparing the dam locations to the Atlas-Cnty file. One dam was deleted because it was described as being in Maryland but had coordinates that placed it in Virginia.
Invalid values for owner type (197 records), dam type (10 records), and year completed (3 records) were changed to blanks to indicate that the values are unknown. The attribute Purposes contained some invalid codes; these were removed but valid codes and duplicate codes were retained. Thirty-nine records contained a value of -9.9 for Nid_height. The appropriate value for each record was determined by looking at the dam height, structural height, and hydraulic height values in the source data. One invalid value for hazard was changed to U to indicate that the hazard potential is unknown.
The shape file was converted to an ArcInfo coverage and then converted to NAD 83 for display purposes. The result was then converted back to shapefile format.

Process_Description:

GeoPlan downloaded this data on May 04, 2011 from the National Atlas web site (<http://nationalatlas.gov/atlasftp.html?openChapters=chpwater#chpbio>). When downloaded the data was in the following projections: NAD 83. The data was projected to FGDL Albers NAD 83 HARN. During the QA/QC process the following steps were undertaken:
- Selected points in the State of Florida via an attribute selection (ST = "FL") - Upcased all fields - Added DESCRIPT based on DAM_NAME - Added FGDLAQDATE based on date FGDL acquired the data from the source - Renamed dataset from dams00x020 to mjdams_2006

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.
