Wastewater outfalls regulated by the TCEQ.The TCEQ Wastewater Outfalls layer is primarily used to identify the geographic location of wastewater outfalls within the state of Texas. This data layer can be used for a variety of purposes, including: the plotting of wastewater outfall sites on maps; determining the permitted discharge facilities within a 3 mile radius; determining upstream dischargers; utilization by field personnel; and performing spatial analysis on how the sites affect their surroundings. Below are the explanations for the fields in the Attribute Table.GIS_NUMBER: This alphanumeric field uniquely identifies each wastewater outfall location. The number is a concatenation of the permit number and outfall number.PERMIT_NUM: This alphanumeric field contains the TCEQ water quality permit identification number.OUTFALL: This alphanumeric field contains the outfall number for each water quality permit number (permits may have more than one outfall).STATUS: This one-character alphanumeric field contains a code which indicates the status of each permit. C = current permit. P = pending permit. DTYPE: This one-character alphanumeric field contains a code which indicates the discharge type of each permit. D = Domestic (<1 MGD domestic sewage). W = Wastewater (> or = 1 MGD domestic sewage or process water including water treatment plant discharge). S = Stormwater. M = Mining. Mining permits may have multiple outfalls. Only one discharge outfall location is plotted for mining permits. C = Cooling Water. G = Groundwater. R = Reservoir Discharge. INITIALS: This alphanumeric field contains the initials of the last person who made a change to any field for a particular record.COUNTY: This alphanumeric field contains the name of the county where the site is located.SEGMENT: A 4-digit number representing stream segments monitored for water quality standards by TCEQ that the outfall directly or indirectly discharges into.BASIN: A 2-digit number representing the Texas River Basin that the outfall discharges into. REGION: This two-character field contains the number of the TCEQ region within which the outfall is located.

This layer depicts the official TCEQ Line Segments for the State of Texas as listed in Title 30, Chapter 307 of the Texas Administrative Code (TAC), also known as the Texas Surface Water Quality Standards. These are freshwater and tidal streams that have been individually defined by the TCEQ and assigned unique identification numbers. Intended to have relatively homogeneous chemical, physical, and hydrological characteristics, a segment provides a basic unit for assigning site-specific standards and for applying water quality management programs of the agency. Both "classified" and "unclassified" segments have been included in this layer. Classified segments, also referred to as designated segments, refer to water bodies that are protected by site- specific criteria. The classified segments are listed and described in Appendix A and C of Chapter 307.10. The site-specific uses and criteria are described in Appendix A. Classified waters include most rivers and their major tributaries, major reservoirs, and estuaries. Unclassified waters are those smaller water bodies that do not have site-specific water quality standards assigned to them, but instead are protected by general standards that apply to all surface waters in the state. This layer also identifies which segments and water bodies have been assessed in the 2018 Texas Integrated Report for Clean Water Act Sections 305 (b) and 303 (d). An impaired segment is a water body included in Categories 4 and 5. Category 4 includes impairments that are not suitable for a TMDL or for which a TMDL has already been approved. Category 5 includes impairments which may be suitable for development of a TMDL and comprise the 303 (d) List.

This data set contains small-scale base GIS data layers compiled by the National Park Service Servicewide Inventory and Monitoring Program and Water Resources Division for use in a Baseline Water Quality Data Inventory and Analysis Report that was prepared for the park. The report presents the results of surface water quality data retrievals for the park from six of the United States Environmental Protection Agency's (EPA) national databases: (1) Storage and Retrieval (STORET) water quality database management system; (2) River Reach File (RF3) Hydrography; (3) Industrial Facilities Discharges; (4) Drinking Water Supplies; (5) Water Gages; and (6) Water Impoundments. The small-scale GIS data layers were used to prepare the maps included in the report that depict the locations of water quality monitoring stations, industrial discharges, drinking intakes, water gages, and water impoundments. The data layers included in the maps (and this dataset) vary depending on availability, but generally include roads, hydrography, political boundaries, USGS 7.5' minute quadrangle outlines, hydrologic units, trails, and others as appropriate. The scales of each layer vary depending on data source but are generally 1:100,000.

This dataset provides an additional "Grazing Potential" land use class to the previously published U.S. Geological Survey (USGS) National Water-Quality Program (NAWQA) Wall-to-Wall Anthropogenic Land-use Trends (NWALT) product (Falcone, 2015, USGS Data Series 948). As with the NWALT, the dataset consists of five national 60-m land use grids, for the years 1974, 1982, 1992, 2002, 2012. The only change to the dataset is, for every year, some pixels which are class 50 "Low-use" in the NWALT, are reclassified to a new class 46 "Grazing Potential Expanded". The purpose of the re-classification is to identify areas which are likely to have had at least some grazing activity based on agreement of historical land cover/use datasets, and not already captured as another land use class by the original NWALT. The re-classification occurred as follows: pixel would otherwise be in class 50 (Low Use), is in an Agriculture or Grazed class in Marschner and Anderson (1967), is in an Agriculture or Rangeland class in 1970s-era GIRAS, and is in a Grassland/Herbaceous class (71) in the NLCD 2011, without restrictions to proximity to water or slope.
