Description: This dataset contains the best available locations of springs that have had some data collection or field activities or were included in publications by various agencies. Currently this collection has 1093 unique spring vents, karst windows and associated sinkholes that are recognized in Florida and are represented in this dataset.
Description: A spring is defined as a place where groundwater flows naturally onto the land surface or into a body of surface water. A spring's occurrence depends on the nature and relationships among topography, underlying geologic strata, and aquifer water levels. While some springs are isolated features, many are clustered into spring groups of varying size and areal extent. In addition to providing a unique recreational resource, springs provide important base flow to rivers and streams and critical habitat to plants and animals. Most springs in SJRWMD occur in discharge areas of the Upper Floridan aquifer where limestone is at or near land surface, or where the sediments overlying Floridan limestone have been breached. The majority of the springs in SJRWMD are located along the major river systems of the St. Johns, Ocklawaha, and Wekiva rivers. This data layer also includes surficial aquifer springs, which are now called seeps, under nomenclature recently agreed upon by the Florida Geological Survey. Springs are classified by magnitude based on the volume of flow, or discharge of water. The amount of water that flows from a spring depends on several factors, including rainfall, size of the caverns within the rocks, the water pressure in the aquifer, and the size of spring recharge basin. Human activities can also influence the volume of water that discharges from a spring; for example, increased groundwater withdrawals can reduce the hydraulic pressure in an aquifer, causing water levels to decline and spring flows to decrease. Since springs have dynamic flows dependent on climate, hydrogeology, and others factors, a spring classified as being a certain magnitude at one time may not continue to flow at that rate at other times. Springs are classified by magnitude, which is based on the median value of all discharge measurements for the period of record. First magnitude springs discharge the greatest amount of water. The following is a summary of spring classification magnitude by discharge.
Description: Locations of NWFWMD field verified spring discharge. Includes both Floridan Aquifer and surficial aquifer vents and seeps. Karst windows, sinkholes, and flowing wells are not included. Springs Inventories Reports can be found on the NWFWMD website here:http://www.nwfwater.com/Data-Publications/Reports-Plans/Springs-Inventories.
Description: This data set represents springsheds for St Johns River Water Management District (SJRWMD). A variety of different modeling techniques were used to derive these polygons. This data was originally downloaded in 10 different shapefiles from SJRWMD and merged into one layer. A unique metadata existed for each shapefile. This metadata is a combination of all metadatas. For more detailed information on each springshed it is recommended that you reference the original layers metadata from SJRWMD.
Description: This dataset contains Outstanding Florida Springs (OFS) located in the State of Florida. Section 373.802(4), Florida Statutes (F.S.), defines "Outstanding Florida Springs" or OFS to include all historic first magnitude springs, as determined by the department using the most recent Florida Geological Survey springs bulletin, and the following additional six springs: DeLeon, Peacock, Poe, Rock, Wekiva, and Gemini. OFS do not include submarine springs or river rises. There are 30 OFS springs consisting of 24 historic first magnitude springs and the 6 named additional springs. While the statutory definition includes the spring runs associated with these springs and spring groups, this coverage identifies the WBIDs associated with the OFS spring vents.
Description: This dataset contains Springs Priority Focus Areas located in the State of Florida. As per the Florida Springs and Aquifer Protection Act (part VIII of chapter 373, Florida Statutes), the department delineates priority focus areas for each Outstanding Florida Spring that is impaired by excessive nutrient pollution. Using the best data available, the department delineates the priority focus areas considering groundwater travel time to the spring, hydrogeology, nutrient loads in the springshed, and other factors. The priority focus areas are adjusted to rely upon understood and easily identifiable boundaries such as roads or political jurisdictions. The priority focus areas become effective upon incorporation into a basin management action plan (BMAP).
