Total Maximum Daily Load Program

Disclaimer for 2002 303(d) List GIS Files

The 2002 303(d) Geographical Information Systems (GIS) files were created for reporting purposes by the State and Regional Water Quality Control Boards. These GIS representations of the areal extent of affected waters are only an estimate, and should not be considered authoritative for the development of TMDLs or other regulatory actions. The Total Maximum Daily Load (TMDL) effort may ultimately address more or less area. 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.
