The ORA is pleased to partner with Credit Valley Conservation (CVC) in the Mill Creek Weir Removal Project. Mill Creek is home to an at-risk population of native Brook Trout, and the weir is a barrier to fish passage and prime habitat. Mill Creek is the lowest dam before its confluence with the Credit River.
The concrete weir is broken and cracked, and if individuals from the Brook Trout population were to breach the weir, they could be permanently trapped in a small pool on the other side, with no way back. Removing the weir will remove this hazard, open up 5 km of uninterrupted Brook Trout habitat, and increase Mill Creek’s resilience to a warming climate. The ORA applied for and received a $5,000 Lush grant towards the new detailed channel design. Continue reading →
It is challenging to understand the logic of a November 2021 CBC article that reports, “The Nature Conservancy and the World Wildlife Fund are two environmental groups that oppose new hydro dams because they can block fish migration, harm water quality, damage surrounding ecosystems and release methane and CO2. But they say adding turbines to non-powered dams can be part of a shift toward low-impact hydro projects that can support expansion of solar and wind power.” Whether it’s a new dam or an older retrofitted dam, they will result in the same negative impacts and produce the same amount of methane for 70 to 100 years or more.
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.

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.
