TMDL names, parameters and permit identifiers are stated by the Water Board in SMARTS. The association of a stated receiving-water name to this 2026 303(d) waterbody is a derived exact-name match, and the list is limited to the first 100 permits. No exceedance, violation or compliance conclusion is drawn.
Industrial stormwater facilities geographically associated with this waterbody. These are derived spatial associations, not Water Board findings.
No industrial stormwater facility is geographically associated with this waterbody.
Facility records are official Industrial General Permit registrations, but the association between a facility and this waterbody is derived geographically (proximity or shared HUC12 subwatershed) and is not a Water Board receiving-water determination. Where a permit carries a Water Board-stated TMDL requirement naming this water, it is listed separately above.
