Update: Gorrie Dam on the North Maitland River to be Decommissioned

The Gorrie Dam failed as the result of an extreme rain and flood event in June of 2017.  The dam had failed before, so the ORA advocated for its decommissioning, rather than its repair.

Part of the earthen berm to the south of the dam failed in June 2017. In June 2019, after reviewing a study of alternatives for the dam, the Conservation Authority membership decided to begin the process of decommissioning the structure which is located at Gorrie Conservation Area.

It is crucial that we take action on infrastructure that would put citizens at risk, degrade water quality, threaten our fisheries, or that jeopardize the ecosystem services that healthy rivers provide.

The Maitland Conservation Authority has decided to decommission the dam and will move ahead with decommissioning in 2021.
