Reported volume per year
Gallons, summed from the 8 events that gave a number (7 did not).
- Partly covered or sparse source
7 of 15 events gave no volume as a number (3 gave a range); only numbers are summed. Vermont volumes were range buckets before 2024 (">10,000 to 100,000 gallons"); those records have no number and are not summed.

Hours under advisory per year
Hours under advisory each year; 2026 to date.
- Advisory in effect
- Partly covered or sparse source
5 discharge events have no reported end and no ongoing status; under the status rules they set caution, not an advisory, and add no hours here. 2 events reported to last more than 31 days are counted to 31 days. Official beach and cyanobacteria advisories are counted on water pages only.

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.
