Reported volume per year

Gallons, summed from the 26 events that gave a number (49 did not).

Partly covered or sparse source

49 of 75 events gave no volume as a number (47 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.

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.
