Current status

No current status shown

This badge describes the water outline. Check the downstream stretches below for discharge statuses.

No current status is assigned to this water outline. Check the water page for reports and any estimated downstream stretches.

Why this status: No current status: no report we track sets a status on this water outline now.

How long each status lasts, and why

Sources checked: ECHO NPDES Sewer Overflow and Bypass Event Dataset (last successful check 2026-11-02 15:54 UTC); NBC CSO Alarm Map live outfall status (JSON) (last successful check 2026-11-02 15:55 UTC). Status by DirtyWaterWatch, updated 2026-11-02 16:21 UTC.

No status does not mean the water is safe. Follow posted signs and local health advice.

Dashed river stretches are estimates.

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.
