With over 50,000 miles of rivers and streams, 7800 lakes, and 4000 square miles
of estuaries, Florida has an abundance of surface waters that are used for a
variety of purposes by the people who live and work here, by those who are
visiting, and by the fish and wildlife that also depend on these waters. To manage surface waters of the state, Florida has developed a surface water quality standards system. The components of this system include: classifications criteria, an antidegradation policy, and special protection of certain waters. The federal Clean Water Act provides the statutory basis for state water quality standards programs. The regulatory requirements governing these programs (Water Quality Standards Regulation) are published in 40 CFR 131(PDF). States are responsible for reviewing, establishing, and revising water quality standards. The Clean Water Act requires that the surface waters of each state be classified according to designated uses. Florida has five classes with associated designated uses, which are arranged in order of degree of protection required: Class I Potable Water Supplies Fourteen general areas throughout the state including: impoundments and associated tributaries, certain lakes, rivers, or portions of rivers, used as a drinking water supply. Class II Shellfish Propagation or Harvesting Generally coastal waters where commercial shellfish harvesting occurs. Class III Recreation, Propagation and Maintenance of a Healthy, Well-Balanced Population of Fish and Wildlife The surface waters of the state are Class III unless described in rule 62-302.40 F.A.C. Class IV Agricultural Water Supplies Generally located in agriculture areas around Lake Okeechobee. Class V Navigation, Utility and Industrial Use. Currently, there aren't any class V bodies of water. The Fenholloway River was reclassified as Class III in 1998 To protect these present and future most beneficial uses of the waters, water quality criteria have been established for each classification. While some of these are intended to protect aquatic life, others are designed to protect human health. The listed criteria are more protective of both aquatic life and human health, and are located in rules 62-302.500 and 62-302.530 of the Florida Administrative Code. Water quality standards also include general provisions for pollutants which are not specifically listed. |
A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare not suitable for some project, analysis, or modelling 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. 1:250000 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 analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References sectionand the Data Source Contact section of this documentation.

The 1:100,000 mylars were used to digitize class 1, 2, and 3 waters. The polygons were attributed with the water class according to DEP documents. The Lambert Equal Area projection was projected to Albers Conformal Area then exported using ARC/INFO v. 6.1.1 for VMS on a VAX. The export file was ftp'd to a DEC Alpha Unix system running ARC/INFO v. 6.1.2 then imported and inserted into the county library. ORIGINAL SOURCE DATA CREATOR AGENCY/ORGANIZATION : GEONEX, Inc.
