Item
Item Description
OBJECTID Internal feature number.

Shape Feature geometry.

NWF_ID A unique identifier for a given site record. Automatically assigned.

SITE_ID USGS 15-digit ground water site identification number. Site_ids were obtained from both the USGS and the NWFWMD.

COUNTY The county the spring is located.

DESCRIPT Based on SPRING_NAM.

FGDLAQDATE The date FGDL acquired the data from the source.

AUTOID Unique ID added by GeoPlan

Magnitude	Metric Units       	English Units
1 		>2.832 cms        	100 cfs (. 64.6 mgd)
2 		0.283 to 2.832 cms 	10 to100 cfs (. 6.46 to 64.6 mgd)
3 		0.028 to 0.283 cms	1 to 10 cfs (. 0.646 to 6.46 mgd)
4		0.0063 to 0.028 cms 	100 gpm to 1 cfs (. 100 to 448gpm)
5  		0.631 to 6.308 lps 	10 to 100 gpm
6  		0.063 to 0.631 lps 	1 to 10 gpm
7 		0.473 to 3.785 lpm  	1 pint/min to 1 gpm
8 		< 0.473 lpm 		< 1 pint/min

cms = cubic meters per second lps = liters per second
cfs = cubic feet per second pint/min = pints per minute
mgd = million gallons per day lpm = liters per minute
gpm = gallons per minute
Notes regarding magnitude - One discharge measurement is enough to place a spring into one
of the eight magnitude categories. However, springs have dynamic flows. A spring
categorized as being a first-magnitude spring at one moment in time may not continue to
remain in the same category. Therefore, the magnitude of the spring is to be based on the
median value of all discharge measurements for the period of record (FSNC, 2003). The
median of a set of scores is the middle value when the scores are arranged in increasing
(or decreasing) order (Modified from Triola, 1998).

The Northwest Florida Water Management District (NWFWMD or District) stretches 
from the St. Marks River Basin in Jefferson County to the Perdido River in 
Escambia County. The District is one of five water management districts in 
Florida created by the Water Resources Act of 1972.  The District has worked 
for decades to protect and manage water resources in a sustainable manner for 
the continued welfare of people and natural systems across its 16-county region.  
It serves Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, 
Leon, Liberty, Okaloosa, Santa Rosa, Wakulla, Walton, Washington and western 
Jefferson County.

Purpose of the data is to manage information about ground and surface 
water under the District's jurisdiction.

Accuracy is not always verified.  Precision and accuracy 
are variable, depending on the method used to develop
the data, geographic information system, global 
positioning satellite, survey, topographic map.

Accuracy is not verified. Precision and accuracy are variable, depending on the data source.

Data were collected from a number of difference sources, accordingly, the quality 
is variable. The data are presumed to be accurate, but are subject to revision, 
amendment and deletion.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. 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.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.

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. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
Tabular data is recorded everyday into Oracle database.  GIS layer 
is updated overnight to reflect the data entered the day before.  
Then the layer is inserted into SDE. Updated every night
Process Date: 20110201

GeoPlan Center Process Steps: Geoplan acquired the data via email from the NWFWMD on February 1, 2011. The data downloaded was in shapefile format packaged together in a zip file called NWFWMD_SPRINGS.ZIP. The shapefile was extracted and originally named: NWF_SPRINGS. The data was in the following projection: NAD_1983_UTM_Zone_16N The following tasks were undertaken: - Reprojected to the FGDL Albers NAD83 HARN projection. - All records were uppercased. - Changed original layer name from NWF_SPRINGS to springs_nwfwmd_2011. - Dropped the COMMENTS field. - Added the DESCRIPT field based on SPRING_NAM. - Added the FGDLAQDATE based on the date GeoPlan acquired the data from the source. Process Date: 20110207
Data imported to ArcSDE and exported as a shapefile. Process Date: 20110214
