How it tells the public
None found on newportvermont.org (only a general Facebook page, https://www.facebook.com/Newport.Vermont/). Presumably the state ANR system. | Statewide: every VT permittee must post a public alert at https://anrweb.vt.gov/DEC/WWInventory/SewageOverflows.aspx within 1 hour of discovery (10 V.S.A. § 1295(b)).
Source: the project's research on each operator's notification channel (research/<state>/dischargers.json), checked by fetching the operator's pages.
Outfalls
Source: water outlines from OpenBoatLaunch and OpenStreetMap contributors (ODbL); outfalls from EPA ECHO and the state outfall layers; modeled reaches computed by DirtyWaterWatch from USGS NLDI, NHDPlus and the nearest USGS gauge (Jobson 1996); basemap OpenFreeMap and OpenMapTiles.

Reported volume per year
Gallons, summed from the 2 events that gave a number (11 did not).
- Partly covered or sparse source
11 of 13 events gave no volume as a number (11 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

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.
