Lake Huron Chinook salmon in Providence Bay waters have more of a reproductive chance this spawning season thanks to the joint efforts of Manitoulin Streams, Central Manitoulin, Ministry of Natural Resources and the Department of Fisheries and Oceans.
Every year the mouth of the Mindemoya River in Providence Bay becomes obstructed by a large sand bar, created by coastal wave action and a lack of water coming downstream, explained Marcus Mohr, Manitoulin Streams coordinator. |

The loss of water during the summer dry season and into the fall reduces the velocity of the river that results in the water taking a path parellel with the beach, eventually making a shallow trickle out into Lake Huron,” Mr. Mohr explained in an email. “This shallow mouth is approximately three inches deep and cannot accommodate the spawning salmon which often die on the resulting sand bar while trying to access the critical upstream habitat.” |
