To provide a spatial representation of the assessed and pollutant-impaired water bodies in California for the 2012 listing cycle.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Under Section 303(d) of the Clean Water Act, states, territories and authorized tribes are required to develop a list of water quality limited segments. Waters on the list do not meet water quality standards, even after point sources of pollution have installed the minimum required levels of pollution control technology. The Clean Water Act requires that these jurisdictions establish priority rankings for water on the lists and develop action plans, called as Total Maximum Daily Loads (TMDL), to improve water quality.</SPAN></P><P><SPAN>Every two years, the California State Water Resources Control Board submits a report on the State's water quality to the U.S. Environmental Protection Agency pursuant to Section 305(b) of the federal Clean Water Act. The Report provides water quality information to the general public and serves as the basis for U.S. EPA 's National Water Quality Inventory Report to Congress.</SPAN></P><P><SPAN>This shapefile is a compilation of all linear water bodies (rivers, streams, coastlines) in California assessed under Sections 303(d) and 305(b) of the Clean Water Act for the 2012 listing cycle. Each water body is assigned a unique Water Body ID (WBID) number as well as selected associated information (water body name, Regional Water Quality Control Board number, etc.). Water bodies listed as impaired under CWA Section 303(d) may be identified by the value of 1 in the LISTED column of the attribute table, or by the value of 4a, 4b, or 5 under the INTEGRATED_REPORT_CATEGORY column.</SPAN></P><P><SPAN>The majority of water bodies in the North Coast, Lahontan and Colorado River Regions have been mapped based on 1:24,000 scale National Hydrography Dataset (NHD) features. All other features were mapped based on 1:100,000 scale EPA Reach File 3 features.</SPAN></P></DIV></DIV></DIV>
