FEATURE ATTRIBUTE TABLES CODES AND VALUES:
item item description
GIS-ID Numeric ID
NAME Spring name
FIPS FIPS County code
CFS Average spring discharge in cubic feet per second
PU Planning Unit
COUNTY County in which the spring is located
MGD Million of Gallons Per Day - flow rate (see NOTES for variation)
LATITUDE Latitude location of spring
LONGITUDE Longitude location of spring
PLAN_UNIT Planning Unit
PU-ID Planning Unit basin ID
NOTES B MGD value in Units of Gallons per minute
C Springs cited in Tibbals, C.H. 1990 Hydrology of the Floridan Aquifer System
in East-Central Florida; discharge averaged from Tibbals and USGS
D Springs identified solely from quad sheets
E Discharge and lat-long information came from the SJRWMD, TDS Average Spring Discharge
Measurments USGS vs SJRWMD. The discharge is the average value of the USGS and
SJRWMD data as of 10/14/91.
F Data from the USGS
G Lat and long data from GeoTrans Inc., Wekiva River Basin Modeling Study, May 1991
H Lat and long from the USGS
I Lat and long digitized from quad
J USGS Altamonte has a discharge reading of 10.6 CFS in 1935 - it is also noted with this data
the spring backs up when the river gets high and the flow has been known to reverse.
K probably less than a few CFS - Rick Speckler, USGS
L rock aquifer or Upper Floridan mixing w/surficial
M surficial
N pseudospring
DESCRIPT Based on NAME item
USER NOTES:
There are 51 springs in this coverage, all within the SJRWMD. The USGS Geographic Names Information System only lists 27 springs within the SJRWMD.
FGDL QUALITY ASSURANCE STATUS:
-Reprojection into FGDL format -Tolerance set to FGDL standards -Added NOTECODE and DESCRIPT items
REFERENCES:
Lat/longs primarily from the Florida Bureau of Geology Bulletin No. 31 (revised) 1977. The coverage was generated by Division of Groundwater Programs staff.
DATA LINEAGE SUMMARY:
This data layer was originally created in 1993 by Division of Groundwater Programs staff. It is a static springs location data layer for general mapping purposes. September, 1996: This dataset was projected from Stateplane, East Zone, NAD 1927 to UTM, Zone 17, NAD 1983, 1990 Adjustment. March, 1999: This dataset was copied to double precision, and its processing tolerances were set to District standard values.
