How it tells the public
CT DEEP Performance Dashboard (QScend QAlert reports shown in Zoho Analytics open views: https://deepct.qscend.mygovcenter.com/cms/cms?id=1); X/Twitter @CTSewageSpills (manual DEEP posts). Statutory local notice: operator must notify the chief elected official and local health official within 2 h; they must inform the public within 2 h of receipt (CGS 22a-424a(c)(3)) - channel varies by town. MDC itself: no CSO event page found on themdc.org; 'MDC Alerts' (Everbridge, https://member.everbridge.net/453003085612528/new) is described as water/sewer emergencies (water main breaks), not CSO notices; X @mdcwater, Facebook mdcwater; physical outfall signs ('Wet Weather Sewage Discharge Outfall #040'). Clean Water Project site thecleanwaterproject.com has no event feed.

Discharge events by outfall
The 10 outfalls with the most events of 540, all years.
CT DEEP dashboard records begin 2021-12-02; where CT DEEP's annual report covers a discharger's month, the annual report is counted instead. CT DEEP annual reports (Sewage Right-to-Know) cover 2021-01-01 to 2026-11-02. CT DEEP's reporting archive runs 2016-07-04 to 2021-12-02.

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.
