Purpose

Use Constraints Use Limitation: The 2006 303(d) List GIS shape files and associated 303(d) list excel tables containing the information shown on the lists are provided on this State Water Resources Control Board website for public use. These GIS files and associated 303(d) tables can be linked by the common field "WBID" (Water body ID). These GIS representations of the areal extent of affected waters are estimated and should not be considered authoritative for the development of TMDLs (Total Maximum Daily Load) or other regulatory actions. The TMDL effort may ultimately address more or less areal extent than shown in these GIS files. Mapping the 303(d) listed waters is a work in progress and will be updated during each listing cycle to better define the impacted areas.; Other: Cite this dataset when used as a source.; Other: The 2006 303(d) List GIS shape files and associated 303(d) list excel tables containing the information shown on the lists are provided on this State Water Resources Control Board website for public use.
