Description:

Abstract:

This dataset consists of the 303(d) listed impaired waters for the State of Florida. The State will use this list to aid in planning for the development of Total Maximum Daily Loads (TMDLs) for each pollutant of concern for water segments on the 303(d) list. A TMDL is the amount of pollutant that a waterbody can receive and still meet applicable water quality standards and its designated use. The 303(d) list is derived from information in the 305(b) report.
EXPLANATION OF PROCEDURES USED TO TRANSFORM THE DATA : The 1998 303(d) coverage was created from the 1996 305(b) shapefile with modifications to the table. The WBID is the unique identifier for each of the waterbodies. The numbers under each of the water quality parameters (ex: turb are the annual medians that are found in the 1996 305(b) report.

This dataset consists of the 303(d) listed impaired waters for the State of Florida. The State will use this list to aid in planning for the development of Total Maximum Daily Loads (TMDLs) for each pollutant of concern for water segments on the 303(d) list. A TMDL is the amount of pollutant that a waterbody can receive and still meet applicable water quality standards and its designated use. The 303(d) list is derived from information in the 305(b) report.
EXPLANATION OF PROCEDURES USED TO TRANSFORM THE DATA : The 1998 303(d) coverage was created from the 1996 305(b) shapefile with modifications to the table. The WBID is the unique identifier for each of the waterbodies. The numbers under each of the water quality parameters (ex: turb are the annual medians that are found in the 1996 305(b) report.
(Creation of the 1996 305(b) dataset) Statewide basins coverage was converted into a shapefile and subdivided into 8 smaller units by Joe Hand. Additional basins were created in ARCVIEW (For information on the procedures and rationale used to subdivide the statewide coverage and create these new basins, contact Joe Hand). The eight shapefiles were used as a source for making an updated statewide 305b coverage. Each shapefile was converted into an ARC/INFO REGIONS coverage using SHAPEARC command with the subclass option. Coverages were projected from Decimal Degrees NAD27 to Albers-Hpgn. Topology was rebuilt using the CLEAN command. A tolerance of 1 was used for fuzzy and dangle length. The regions coverages were converted to ARC polygon coverages using the REGIONPOLY command. The eight polygon coverages were mapjoined using the MAPJOIN command. Sliver polygons (coverage-id = 0) were eliminated with the ELIMINATE command. As a final check, the linework of the coverage was checked using each of the individual eight coverages as a backcover in ARCEDIT. Some additional small slivers were deleted manually in ARCEDIT. To assure that each polygon has a unique WBID (water body id), a summary statistics on item WBID was performed in ARCVIEW. There were 18 duplicated WBID'S. They were reassigned unique WBID'S following the guidelines supplied by Joe Hand. A shapefile was made of this coverage. DBASE tables (containing summaries of chemical and biological data) from the 305b report were joined to the attribute table of the shapefile in ARCVIEW. WBID was used as the joinitem. For a full description of the attribute table contact Joe Hand. The shapefile with the joined attribute table was converted into an ARC/INFO polygon coverage using SHAPEARC (with regions option), CLEAN (fuzzy and dangle length 1) and REGIONPOLY commands. This resulted in the 1996 version of the 305(b) data.
