The Problem: All over the Great Lakes popular spawning areas for a variety of fish species including salmon and trout have been destroyed and water quality has suffered due to human and livestock contamination.  On Manitoulin Island a large number of streams, rivers and creeks have been devastated by past logging activities, improper land use practices, unrestricted livestock access and fluctuating water levels. The results of this activity are erosion, sediment discharge and loss of the riparian area.

  1. Erosion causes the river to widen which decreases the depth, making it harder for spawning fish to navigate.
  2. Sediment discharge covers valuable spawning beds and invertebrate habitat.

  3. Destruction of the vegetation in the riparian zone means that:

    Nutrients aren't being filtered, the river banks are not being stabilized by plant root systems, fish do not have shelter, the water temperature is increased and there is less food for the invertebrates which in turn feed the fish.Unrestricted livestock access has contributed to some of the above factors and allowed unfiltered fecal matter to flow into the streams.


The Solution:

  1. Installation of fencing to restrict livestock access to certain points on the river

  2. Creating livestock watering pads or installing remote watering devices will decrease erosion and the time livestock spend at the river's edge

  3. Planting grass, shrubs and trees to prevent erosion and provide shade/shelter

  4. Stabilizing the shoreline with root wads and boulders. Narrowing the river to increase depth.

  5. Installation of in stream habitat like spawning beds, boulders, LUNKER's and weirs.

The Benefits of Clean Water :

Without clean water many organisms cannot thrive or exist. It is estimated that close to 35 million humans directly depend on the Great Lakes for drinking water.

Community Stewardship:

This initiative will promote natural resource sustainability, educate the public and build the capacity within the community to better understand and manage our aquatic resources. We bring together a wide variety of community members in the rehabilitation efforts. College and University students will use the sites for valuable training. Grade school students are given tours of the sites. High school students enjoy tours as well as gaining volunteer hours doing things such as tree planting. Stewardship Committees and Lake Associations are involved in rehab work and restocking efforts.

Economic Spin Off:

Economic spin offs will include enlisting local businesses for materials and labour for the projects, improving the health of humans, livestock and wildlife and long term economic sustainability such as angling tourism. Tourism and the economy in this area have already suffered due to the damage done to the rivers fish population. Rehabilitation efforts will prevent major issues that could result from not taking action. For example life robbing impacts of algal blooms, contaminated water, further depleting the fisheries, lost recreational/tourism opportunities and lost jobs/revenue.
