TITLE: VERIFIED IMPAIRED FLORIDA WATERS: CYCLE 1 GROUP 1-5 BASINS AND CYCLE 2 GROUP 1-3 BASINS - 2010

Geodataset Name:       IMPAIRED_WATERS_MAY10
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         2993
GENERAL DESCRIPTION:
The verified list of impaired waters is the list of Florida's waterbodies that do not meet or are not expected to meet applicable water quality standards with technology-based controls alone. The Secretary of FDEP adopted verified lists for the Cycle 1 Group 1-5 basins and for Cycle 2 Group 1-3 Basins. The Secretary of FDEP adopted final list of waters delisted from the 1998 303 (d) list and the Cycle 1 Group 1 verified list. The FDEP must develop pollutant loading limits known as Total Maximum Daily Loads (TMDLs) for these waters. A TMDL is the maximum amount of a pollutant that a waterbody can receive and remain healthy. It identifies the amount of a pollutant that must be removed from an impaired waterbody to restore its health. This is an update to the impaired_waters_aug09 layer.

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

GeoPlan using the IMPAIRED_WATERS_SEP08 attribute table as a template appended all seven layers together to create one statewide impaired waters layer. GeoPlan added a SOURCE field for this edition, the original layer names as found above can be located for each feature in this field. GeoPlan also joined the WBID layer and populated the same fields FDEP had for the previous layer. - A DESCRIPT field was added based on BASIN_1. - FGDLAQDATE was added based on date downloaded from source. - Deleted Object_ID, Area, and Length fields. - Upcased all records in the table Process Date: 20100505
