USER NOTES:

Tests for integrity have not been performed.

Features represented have not been tested for completeness.

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

Procedures Used: State Water Quality Agencies supplied EPA's Office of Water lists of waters reported under 305(b). These lists contained text which identified the locations of individual waters on their list. Many states also submitted GIS coverages and/or maps that outlined the spatial extent of their listed and assessed waters. These base materials were used by EPA to code the spatial extent onto the appropriate feature of NHDPlus to create Reach Address Database events. Revisions: The event tables were sent to each state for review and comment.

To identify the spatial extent of waters listed under the 305(b) program attributed as being assessed in the ATTAINS database. These waters can be linked to the 305 (b) information stored in the EPA's Assessment and TMDL Tracking and Implementation System (ATTAINS) for query and display. Use the Source_FeatureID field and Cycle_Year field to link indexed assessed waters to the EPA's ATTAINS Database.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. 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.

DATA LINEAGE SUMMARY:

Each state provided a marked-up map or existing GIS coverage denoting the location and extent of each waterbody. Event tables were created by conflating the state's data to NHDPlus v2.1 hydrology. Event identifiers were populated with the 305(b) codes supplied by each states' list. Process Date: 20150501 National Extract Created Process Date: 20150501 Metadata imported.

River segments, lakes, and estuaries designated under Section 305(b) of the Clean Water Act. 305(b) Waterbodies are coded onto route.rch (Transport and Coastline Reach) feature of NHD to create Point and Linear Events. Linear events, Point events and waterbody shapefiles are attached to a reach in NHD to represent assessed and non-assessed waters. 305(b) Waterbodies are coded onto the region reach feature of NHD to create Waterbody shapefiles. In addition to NHD reach indexed data there may also be custom events (point, line, or polygon) that are not associated with NHD and are in an EPA standard format that is compatible with EPA's Reach Address Database. These custom events are used to represent locations of 305(b) waterbodies that are not represented well in NHD. https://www.epa.gov/waterdata/waters-geospatial-data-downloads#305bWatersAsAssessed ----------- Reprojected to FGDL Albers using the following transformation: WGS_1984_(ITRF00)_To_NAD_1983 + NAD_1983_To_HARN_Florida ----------- Uppercased all fields except those containing website links. ----------- Added and populated the following fields.
