Description: These spatial features show the Oregon waters where Total
Maximum Daily Loads (TMDLs) have been completed and approved by
EPA. TMDLs that have been withdrawn, disapproved by EPA, or replaced with a
newer TMDL are not shown.
A Total Maximum Daily Load (TMDL), or clean water plan, is a
science-based approach to cleaning up polluted water so that it meets state
water quality standards. A TMDL is a numerical value that represents the
highest amount of a pollutant a surface water body can receive and still meet
the standards.
The federal Clean Water Act requires states, or the U.S.
Environmental Protection Agency, to develop a TMDL for each water body on the
state's polluted waters list, also known as the 303(d) list (Integrated Report).
The TMDL process is just one strategy used to clean up polluted waters.
