How it tells the public
State only. 2025 annual report: 'The City completes public notification requirements through the ANR notification system as required by Condition II.A.2 of the Discharge Permit.' The city has a CSO info page (https://www.stalbansvt.com/cso) with LTCP documents but no alerts. | 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.

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.
