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.
