The US Geological Survey Chesapeake Bay Watershed Land Cover Data Series, 2011 edition, (CBLCD-e11) consists of Level I Land Cover data for the years 1984, 1992, 2001, 2006 and 2011. It consists of a series of five 8-bit unsigned integer raster data files of 30 meter spatial resolution in Albers Conic Equal Area projection, NAD83 datum. The 1984 – 2006 data layers were created by aggregating most Level II Anderson classes of the USGS CBLCD Land Cover Data Series released in 2010 (Irani and Claggett, 2010).

The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an EPA-approved TMDL established, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution and is not caused by a pollutant. Therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's...

State of Utah's assessed lakes coverage (converted to 30m raster coverage) based on data created for the draft 2014 Integrated Report from Utah Division of Water Quality (DWQ) Feb, 2015. The Utah lakes depicted here were sampled in order to determine whether each water body should be categorized as impaired (under the 2014 draft report guidelines) based on EPA designations. These GIS data can be used to identify potentially impaired waters, based on statewide Assessment Unit (AU) polygons for Utah (USGS 5th and 6th hydrologic unit boundaries as developed by USGS in Salt Lake City, call Karen Hansen, 801-908-5038 for more info.)

Updated EPA impaired waters data was combined with the data used in the 2011 COP REA by the Conservation Biology Institute. The three dataset types (point, line, polygon) were converted to raster (at 30m resolution) to facilitate coverage calculations across reporting units. The resulting EPA impaired waters raster was clipped to the study area of Utah and the Colorado Plateau Ecoregion.Original Metadata:The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act.
