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.

Upper Dam diverts flow from East Channel into West Channel of Eramosa River
The East Channel is a stretch of the Eramosa River that runs through the village of Eden Mills, between Rockwood and the city of Guelph. The East Channel was once a pristine river ecosystem; however, for years, it has been in a state of decline. Why? Because a private dam was built without an environmental assessment or permits in the early 1990s, and blocks water from flowing down into the East Channel during the low flow summer months when the river and aquatic life need it the most. Even though there could be as much as 20 inches of water in the river at the entrance of the East Channel, the Upper Dam blocks the flow completely at those times. This dam continues to cause significant and alarming environmental harm to the East Channel’s river ecosystem. Continue reading
In November of 2015, Ontario Rivers Alliance (ORA) commented on EBR 012-5093, regarding a Technical Bulletin for the Alterations, Improvements and Repairs of Existing Dams. You can find our submission on our Blog here. On March 24, 2016, ORA received a Decision Notice, as well as the approved Technical Bulletin. Continue reading
