All tracked reports and advisories
149,002 records from the sources we track, newest first. This list includes discharge reports, advisories and historical totals. Earlier versions are marked; the newest version sets the map status.
Sources are named in each row. List updated 2026-11-06 09:03 UTC.
New since the last update
Notices our checks found after the latest site update. They are not yet linked to a water's status; the map and lists change at the next update. A notice is not a water-quality test.
Filter all 149,002 records Loads the last 90 days first, then the years a filter needs
Dates use the discharge start, or the report date when the start is missing.

Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater. Combined sewer overflow (CSO): sewage mixed with rainwater spills from a shared sewer system. Cyanobacteria (harmful blue-green algae) can make water unfit for contact; the issuing authority decides when its advisory ends.
