TITLE: WBIDs with Verified Nutrient or Dissolved Oxygen Impairment or Adopted Total Maximum Daily Loads (TMDL) or Reasonable Assurance Plans (RAP) for the State of Florida - 2013.

Geodataset Name:       VI_TMDL_RA_MAY13
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         253
GENERAL DESCRIPTION:
This dataset contains Water Body Identification number (WBID) polygons that have verified nutrient and/or dissolved oxygen (DO) water quality impairments, or have an FDEP adopted TMDL for nutrients or DO, or are within the watershed area of a Reasonable Assurance Plan that addresses nutrient or DO impairments. Currently all WBID numbering is referenced to WBID Run 47. As of now data are only available for South Florida Water Management District (SFWMD) and Southwest Florida Water Management District (SWFWMD) areas within Florida Department of Transportation (FDOT) District 1. FDOT District 1 includes Charlotte, Collier, De Soto, Glades, Hardee, Hendry, Highlands, Lee, Manatee, Okeechobee, Polk, and Sarasota Counties. As more data become available this future statewide layer will be updated. Please Note: this layer has been created by FDOT for FDOT planning and consultants use. The FDEP maintains their own statewide impaired waters layer (IMPAIRED_WATERS_*.shp) which is also available on FGDL.

WBID Unique Alpha Numeric Water Body Identification. WBIDs make up a statewide polygon layer in which each polygon has a unique Water Body Identification number (WBID). The assessment units are drainage basins, lakes, lake drainage areas, springs, rivers and streams, segments of rivers and streams, coastal, bay and estuarine waters in Florida. The polygons roughly delineate the drainage basins surrounding the water body assessment units. The WBIDs are used in the Basin Rotation Total Maximum Daily Load (TMDL) program as well as other applications. WBIDs are assigned a FDEP district as part of their attribution. There are multiple instances where a WBID may be assigned to an FDEP district, but physically fall within the boundary of a different district. This is because WBIDs are grouped together into basins called Planning Units and there are instances where a Planning Unit basin will fall acrossFDEP district boundaries. In these cases, for consistency's sake, all the WBIDs that are in the Planning Unit will be assigned to the same FDEP district. For information on which district the WBID physically falls in, please refer to the FDEP Regulatory Districts layer.

Basin The Basin name of the waterbody being assessed.

PlanUnit Grouping of WBIDs within a larger basin.

Wtrbody The name of the waterbody being assessed.

WtrType Type of waterbody. (Beach, Blackwater, Coastal, Estuary, Lake, Spring, Stream)

Class Surface Water Classification Value.

NutrImp Has Nutrient Impairment.
1 = Yes

0 = No


DOImp Has Dissolved Oxygen Impairment.
1 = Yes

0 = No


TMDL Has FDEP Adopted TMDL Status. Unless updated impairment information was provided by FDEP, for water bodies with adopted TMDLs, the impairments listed are the impairments addressed by the TMDL. The water body may or may not still be impaired for those parameters. A project specific determination is needed to determine if nutrient loading calculations are required.

The State of Florida "verified list" of impaired waters is the list of Florida's water 
bodies that fail to attain any of its designated uses and/or meet the minimum 
criteria for surface waters established in the Surface Water Quality Standards 
(62-302, F.A.C.) and the Impaired Waters Rule (IWR, 62-303, F.A.C.). The entire 
state of Florida is divided into five basin groups in which each water body is 
re-assessed on a rotating basis every five years. FDEP develops TMDLs for 
waters on its verified list, or in the alternative, local stakeholders can develop and 
implement a RAP to restore water quality. 

The attached lists/maps have been reviewed and approved by SFWMD, 
SWFWMD and FDEP for use by consultants to FDOT District 1 to determine if 
nutrient loading calculations are required. The maps/lists include WBIDs that 
have a TMDL or are within a RAP watershed and require net improvement.
The maps/lists will be updated annually (or sooner) as each new cycle of impaired 
waters is approved. The list is current through the Group 1, Cycle 3 assessments 
adopted in February 2013. It is anticipated that the Group 2, Cycle 3 assessments 
will be adopted in Fall 2014, and this list will be valid until that time. Questions 
about this specific dataset should be addressed to:

Watershed Assessment Program
Florida s rivers, streams, lakes, estuaries, and coastal waters are spectacularly 
beautiful. More than that, they are essential natural resources, supplying the water
necessary for aquatic life, both large and microscopic; drinking water; recreation; 
industry; fishing and shellfish harvesting; and agriculture. Florida's multi-billion 
tourist industry would vanish if our water resources were irreparably degraded.

Protecting these abundant water resource, restoring them when they become 
damaged because of unmanaged growth and development, and preserving them 
for the future is your responsibility and ours.

DEP's Divisions of Water Resource Management and Environmental Assessment 
and Restoration implement a wide range of programs to protect and restore 
Florida's surface waters. Tour this website and you will find dozens of different 
strategies and activities underway to benefit water quality. At the heart of these 
efforts, particularly in identifying water quality problems and establishing clean-up 
objectives, is the Watershed Assessment program.

Total Maximum Daily Loads Program
What is a TMDL?

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 clean up 
the water body.

The threshold limits on pollutants in surface waters--Florida's surface water quality 
standards on which TMDLs are based--are set forth primarily in rule 62-302, Florida 
Administrative Code, and the associated table of water quality criteria.

What are the basic steps in the TMDL program? How does it work?

        Assess the quality of surface waters--are they meeting water quality standards?
        Determine which waters are impaired--that is, which ones are not meeting water 
             quality standards for a particular pollutant or pollutants.
        Establish and adopt, by rule, a TMDL for each impaired water for the pollutants of 
             concern--the ones causing the water quality problems.
        Develop, with extensive local stakeholder input, a Basin Management Action Plan (BMAP) that....
        Implement the strategies and actions in the BMAP.
        Measure the effectiveness of the BMAP, both continuously at the local level and 
             through a formal re-evaluation every five years.
        Adapt--change the plan and change the actions if things aren't working.
        Reassess the quality of surface waters continuously.

The Divisions are working on a more comprehensive approach to protecting Florida water 
quality involving basin-wide assessments and the application of a full range of regulatory 
and non-regulatory strategies to reduce pollution.  The Total Maximum Daily Load (TMDL) 
is the heart of this comprehensive approach.

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
