Since early in 2016, the Ontario Rivers Alliance, Thames River Anglers Association and several other partners have advocated for the removal of the Springbank Dam on the Thames River. We are happy to report that the City of London is moving forward with its decommissioning.
A Consulting Engineer will be chosen to complete the detailed design for its decommissioning as per the recommendations outlined in the completed One River Environmental Assessment, with an aim for construction in 2021. We are looking forward to the project moving forward in 2021!
We will keep you informed as the project progresses.
The East Branch Weir Removal Project on the Eramosa River is moving ahead. We are pleased to report that all funding is in place, and the Project will be complete within a few days. An excellent outcome for the East Channel and for the community.
The Save the East Channel group and ORA worked with the Eden Mills Eramosa River Conservation Association (EMERCA) to find an environmentally sustainable solution that would improve flow and connectivity in the East Channel.
The City of Cambridge is moving forward on a detailed design plan of the new rebuild of Riverside Dam on the Speed River. Construction is planned for 2022 and work set for completion in 2023. Meanwhile, the full price tag won’t be known until the dam’s design plan has been finalized. This dam has been determined to be at “high risk” of failing within the next 2 to 10 years.
ORA worked extensively towards the decommissioning of this dam. Removing the dam would have been much cheaper, safer and healthier for the riverine ecosystem.
The motion, presented on Monday night, suggested by the committee calls for North Huron Council to approve an engineering study to determine the future of the dam and set out a schedule for fundraising for the rehabilitation of the structure. If that schedule cannot be met, however, the recommendation calls for the removal of the structure.
Ontario has hundreds, if not thousands of dams that are unsafe and no longer serving any useful purpose. These dams are blocking fish passage, degrading water quality, fragmenting habitat, threatening species at risk and sensitive cold water species. ORA is working to take them out. Check out this excellent overview of the problems with hydropower:
This film explores the evolution of our national attitude from pride in big dams as engineering wonders to the growing awareness that our own future is bound to the life and health of wild rivers. Produced by Matt Stoecker & Travis Rummel Directed by Ben Knight & Travis Rummel.
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.
The Rudd Dam’s headpond had essentially turned into a large wetland created by over 100 years of sediment accumulating behind the dam, and the shallow pond’s water temperature was no longer viable brook trout habitat. After the removal of the Rudd Dam the water temperature was reduced and brook trout habitat was made more resilient to a warming climate. It was also an earthen dam that had already failed once, and the dam owner’s objective was to reduce his risk and liability.
