Status now
At least one source we follow covers this water, and nothing it reports applies right now.
Why this colour: No current report: nothing a covering source reports colours this water now. How long a water stays coloured, and why

It is not a finding about the water. Discharges go unreported, reports arrive late, and storm runoff carries bacteria too. Follow posted signs and local health advice.
Rivers are not coloured as a whole: a discharge colours a modeled stretch downstream of its outfall, listed below when there is one.
As of Nov 2, 2026, 6:56 AM EST.

Outfalls are small brown dots.

How these charts are counted
Discharge events are counted once: where a source publishes both public notices and verified reports (MassDEP, Vermont DEC), a discharger's month with any verified report counts its verified reports only, and other months count notices. Revisions are folded into the record they revise, and EPA copies of a state report are not counted twice. Monthly and yearly totals (Maine DEP, EPA discharge monitoring reports, Portsmouth) are shown on their own and never added to the event counts. Hours under advisory follow the map's red rules. A muted band marks periods no source covers: a gap there is missing data, not a quiet month.
