Current status from this report

Discharge or advisory reported on Connecticut River: Discharge reported ongoing. Current rule period ends Nov 13, 2026, 12:30 AM EST. This is not a water-quality test.

Why this status: Discharge or advisory reported: the discharge is reported as ongoing.

Why we use this rule: A report marked ongoing stays red until an end is found or 7 days pass. After 7 days we label the end unconfirmed rather than assume the discharge continues.
