What a 303(d) listing means

The Clean Water Act section 303(d) list names waters that do not meet water quality standards for one or more pollutants or stressors. California publishes it in the Integrated Report; this page shows the 2026 decisions from Appendix A as published.

A listing describes the condition of the waterbody. It does not identify which sources cause the impairment, and it does not by itself place a requirement on any particular facility.
Listed waters do not all have the same status. The Integrated Report category says how an impairment is being addressed: 5, a TMDL is required; 4a, addressed by a USEPA-approved TMDL; 4b, addressed by other pollution control requirements; 4c, impairment not caused by a pollutant. This waterbody's decisions are in category 5.
TMDL requirement status values (such as 5A or 5B) are shown exactly as published in Appendix A.

Industrial stormwater facilities

Evidence: identification corroborated

Shows: the facility named this waterbody as its receiving water in SMARTS, and the name and the facility's location are consistent with it. Does not establish: a discharge pathway, a discharge of any pollutant, or a cause of the listing.

Evidence: geographic proximity

Shows: the facility's reported location is within 1 km of the waterbody's mapped shape. Does not establish: that the facility discharges to this waterbody, or any other relationship.

Report this waterbody as their receiving water Evidence: identification corroborated

No facility's reported receiving water is identified as this waterbody.

Within 1 km of a facility's reported location Evidence: geographic proximity

Spatial proximity only; discharge pathway not established. Being near this waterbody does not mean a facility discharges to it.
