 Florida's waterbody classifications are defined as: 

 1 - Potable water supplies 

 2 - Shellfish propagation or harvesting

 3F - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in fresh water

 3M - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in marine water

 4 - Agricultural water supplies

 5 - Navigation, utility, and industrial use

2

 n is equal to the number of samples. When samples are collected at the same location less than 4 days apart, the median of those results represents a single sample for the purpose of determining n. 

3 The Cycle 1 assessment was done in 2003 and included data from that Verified Period (January 1, 1996 through June 30, 2003).

4 The Cycle 2 assessment is the current assessment and includes data from the Verified Period (January 1, 2001 through June 30, 2008).

 † EPA's Integrated Report Category:

 Where a parameter was 1998 303(d) listed the priority for TMDL development is the year provided and is assigned based on the consent decree schedule.

 Where a parameter was only identified as impaired under the IWR, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or 

 human health, which have been assigned a “high” priority, and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based

 on the following: it is our intent that listings with a "High" priority be addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow,

 and listings with a "Low" priority be addressed within the next 10 years.

 VP - Verified Period (January 1, 2001 through June 30, 2008) * A statewide TMDL for mercury, that will address this waterbody, is scheduled to be completed in 2012.

Beach advisories are based on FL Dept of Health Enterococcus criterion of >103 CFU/100mL or Fecal Coliform criterion of ≥400 CFU/100ml.

Beach advisory data is based on "2006 Beach Advisories" file created 04/16/2007 by Barbara Donner of FDEP.

Fish advisory data is based on "2007 Fish Advisories" file created 07/11/2006 and updated 11/05/2007 by Barbara Donner of FDEP.

The Group 2 Charlotte Harbor Master list is based on IWR Run 35_2.
