 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

 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 the Department's 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.

3 PP - Planning Period (January, 1994 through December, 2003); VP - Verified Period (January, 1999 through June 30, 2006); X/Y (X = Number of exceedances of criterion and Y = number of samples)

*

 A statewide TMDL for mercury, that will address this waterbody, is scheduled to be completed in 2012.
