A monitor activation is not itself a verified discharge — this outfall's monitor was operational 100.0% of 2025 per the audited return. See the method.

Monitor behaviour note: this monitor logged 27 activations under 15 minutes in the last 30 days — a pattern consistent with sensor noise as well as genuine brief operation. Brief activations are recorded and exported, but never counted as dry spills in headline figures.

The audited record

202570 spills · 621h
202448 spills · 411h
202373 spills · 653h

EA EDM annual returns, counted on the 12-24h basis — a different methodology from the live feed's raw durations; the two are never mixed in one figure.

A free, independent push channel — ntfy, not a feature run by this site. Every time this outfall's monitor is recorded starting or stopping an activation, a message is sent to the public topic below. Install the free ntfy app and subscribe to it, or open the web view directly.

A message reports only that a discharge started or ended, with the recorded time — the same monitor-activation fact shown on this page. It carries no rainfall assessment of its own; check back here for that.
