 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 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, population of fish and wildlife, 5 - Navigation, utility, and industrial use.

 The nutrient concentrations represent the 75th percentiles of data from the Verified Period. The target nutrient concentration used in the subsequent TMDL will be determined during the TMDL process.

 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.
