ORA Support for the East Branch Weir Removal Project, Eramosa River

East Channel Dam in low flow summer season – no flow moving through the dam to the East Channel of the Eramosa

The ORA is pleased to support the Eden Mills Eramosa River Conservation Association (EMERCA) application for an EcoAction Community Funding Grant for the East Branch Weir Removal Project on the Eramosa River in Eden Mills, Ontario. This Project includes the removal of an existing steel control structure at the top of the East Channel of the Eramosa River, and the naturalization and remediation of this section of the River. Removing the weir would expand the coldwater fishery, increase flows and build resilience to the effects of a warming climate.
