USER NOTES:

This data is provided 'as is'. GeoPlan relied on the integrity of the original data layer's topology

This data is provided 'as is' by GeoPlan and is complete to our knowledge.

GeoPlan relied on the integrity of the attribute information within the original data.

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. A TMDL is the amount of pollutant that a waterbody can receive and still meet applicable water quality standards and its designated use. This data is provided for use in various planning efforts.

This data is provided 'as is' and its horizontal positional accuracy has not been verified by GeoPlan

This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

REFERENCES: DATA LINEAGE SUMMARY:

The 303(d) list is derived from information in the 305(b) report. EXPLANATION OF PROCEDURES USED TO TRANSFORM THE DATA 07 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. GeoPlan Process Steps: -Downloaded the 303(d) 1998 Impaired Waters shapefile from FDEP website on 7/11/2008 -Downloaded from http://www.dep.state.fl.us/gis/datadir.asp -Added DESCRIPT field -Calculated DESCRIPT field based on WATER_NAME field -Added FGDLAQDAT -Calculated FGDLAQDAT Process Date: 07/14/2008 Inserted into ArcSDE from Shapefile obtained from Matt Foss. Process Date: 03/22/04 GeoPlan downloaded this data set from the FDEP webpage: http://www.dep.state.fl.us/gis/datadir.asp in July 2008. The data was in Albers HPGN. -Added DESCRIPT field based on WATER_NAME to attribute table -Upcased all items in the attribute table -Changed file name from impaired_waters_303d_1998.zip to watqual303d_1998 -Added FGDLAQDATE field based on date GeoPlan received the data Process Date: 20080718 Data imported to ArcSDE and exported as a shapefile. Process Date: 20080718 Dataset copied. Process Date: 20090817
