 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 period of record assessment refers to an evaluation of all data available for a particular waterbody and parameter not just the data within the Verified Period. 

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

5 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:

 1 - Attains all designated uses

 2 - Attains some designated uses and insufficient or no information or data are present to determine if remaining uses are attained

 3A - No data and information are present to determine if any designated use is attained

 3B - Some data and informationare present but not enough to determine if any designated use is attained

 3C - Enough data and information are present to determine that one or more designated uses may not be attained according to the Planning List methodology

 3D - Enough data and information are present to determine that one or more designated uses are not attained according to the Verified List methodology

 4A - Impaired for one or more designated uses but does not require TMDL development because a TMDL has already been completed.

 4B - Impaired for one or more designated uses but does not require TMDL development because the water will attain water quality standards due to existing or porposed measures.

 4C - Impaired for one or more criteria or designated uses but does not require TMDL development because impairment is not caused by a pollutant.

 4D - The waterbody does not meet applicable criteria, but no pollutant can be identified; therefore a TMDL will not be developed at this time.

 4E - Impaired, but recently completed or on-going restoration activites are underway to restore the designated uses of the waterbody.

 5 - Water quality standards are not attained and a TMDL is required.

 Where a parameter was identified as impaired, 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.

* 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 (>103 CFU/100mL) or fecal coliform (>399 CFU/100mL) criteria.

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 Middle St Johns Master list is based on IWR Run 35.
