Blackstone River
River in Massachusetts · near Grafton, Northbridge, Sutton, Uxbridge
Status now
Unresolved: no end reported
A discharge here was reported but its end never was. Sources often skip the "ceased" notice, so after the first week the water is shown hatched yellow until 30 days have passed, and the event stays flagged on its pages after that.
Why this colour: Unresolved: no end reported: no end reported. Rationale: From day 7 to day 30 the reach or water is shown hatched yellow 'unresolved: no end reported', listed under active discharges with that label. (source: data/rules.json) How long a water stays coloured, and why

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.
