TITLE: ADOPTED TOTAL MAXIMUM DAILY LOADS (TMDLS) IN FLORIDA - JANUARY 2012 

Geodataset Name:       ADOPTED_TMDLS_JAN12
Geodataset Type:       SDE Feature Class
Geodataset Feature:    Polygon
Feature Count:         271
GENERAL DESCRIPTION:
This dataset contains Adopted Total Maximum Daily Loads (TMDLs) in the State of Florida. A Total Maximum Daily Load (TMDL) is a scientific determination of the maximum amount of a given pollutant that a surface water can absorb and still meet the water quality standards that protect human health and aquatic life. Water bodies that do not meet water quality standards are identified as "impaired" for the particular pollutants of concern--nutrients, bacteria, mercury, etc.--and TMDLs must be developed, adopted and implemented for those pollutants to reduce pollutants and restore the water body so that designated uses are attained. The threshold limits on pollutants in surface waters--Florida's surface water quality standards on which TMDLs are based--are set forth primarily in rules 62-302 and 62-303, Florida Administrative Code (FAC), and the associated table of water quality criteria. For assessment purposes, the Florida Department of Environmental Protection (Department) has divided the State of Florida into water assessment polygons with a unique waterbody identification (WBID) number for each water segment. 1) Dissolved Oxygen (DO) and Nutrient TMDLs include TMDLs for the following impaired parameters Dissolved Oxygen, BOD, Nutrients, and Un-ionized Ammonia. 2) Bacteria TMDLs include TMDLs that are Fecal Coliform impaired. 3) Other TMDLs include TMDLs for pollutants other than Dissolved Oxygen, Nutrients, and Bacteria, such as Iron, Lead, and Turbidity.

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,

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:
