Mindemoya River - Site MIN-900 & MIN-902
Rehabilitation and Enhancement
This project took place in August 2013, requiring almost a full month of work. Being a very public eye project, much time was spent on site, educating locals and tourists the purpose of this rehabilitation.
Improvements to the river’s hydrological function will better facilitate the flushing of the river mouth, cleaning rock and gravel substrates critical to a wide variety of aquatic organisms, salmonids and other native species that utilize 13.86 kilometers of potential aquatic habitat such as trout, lake sturgeon, bass and walleye to facilitate the completion of their life cycle processes. Temperature increase in this cold water stream and pooling areas for spawning is detrimental to the survival of the fish. Bank stabilization and enhancement of critical in-stream habitat is detrimental to this sensitive eco-system.
A bioengineered cross vein and two j-hooks were placed in carefully plotted locations, to allow for manipulating water flow and scouring. These structures were made of limestone rock purchased locally. Root wads and semi half logs were strategically placed to allow for sweeping and housing aquatic life.
Total accomplishments include:
In partnership with Central Manitoulin, this project was a huge accomplishment. Many businesses and locals were happy to help out and see to it’s completion.
It is projected that the in-stream work completed will provide a faster flow of scouring water to help keep the mouth of the river open for spawning salmon.
The Ontario Rangers had participated in this large project, as well as many volunteers to plant trees. A shoreline cleanup closed this project through WWF, headed up by Manitoulin Streams. Thank you to Central Manitoulin Public School Grade 4 class and volunteers for their help on this restoration.
