Dredging the Mouth of Mindemoya River to Allow Fish Migration

The Municipality of Central Manitoulin in partnership with Manitoulin Streams  will be dredging the sand at the mouth of the Mindemoya River in Providence Bay, ON to allow spawning salmon to access the river. The work will be conducted on Thursday, September 24th, 2026. An excavator will be used to pull sand out of the mouth of the river and it will deposited on the adjacent beach area. 

Wave action and a low flow rate of the Mindemoya River allows sand to build up at the mouth of the river during critical spawning times. This work will allow salmon to migrate into the river system to spawn. The work will enhance the fisheries around Manitoulin Island in Lake Huron and positively contribute to the economic, social and environmental well being of the area.
