Overview

Estuary Curdies River Estuary
Site Dorey Street floating pontoon
Observation ID #14051
Date and Time Friday 9th April 2021 09:40am

Notes

The river was putrid with Blue-Green Algae.

Sludge was backed up around the boat ramp, between the pontoon and the shore, and up onto the shore in most areas.

The smell was disgusting, an obvious health hazard.

Where the sludge was not present, the water was more like soup.
