Total Maximum Daily Load (TMDL) Program

Total Maximum Daily Loads (TMDL) are water quality restoration plans required by the Federal Clean Water Act (CWA) to ensure the attainment of water quality standards in impaired surface water bodies. Impaired surface waters are identified on the CWA 303(d) list. Click here to view the 2006 Section 303(d) List of Water Quality Limited Segments. If you have questions about the Lahontan Region's 303(d) List, contact Judith Unsicker.

Below are the TMDL development projects that the Lahontan Regional Board is currently working on or has completed. Highlighted projects have links to documents or other information available for viewing or downloading.
