Min 620
This summer we worked on trying to improve continuity of rivers so that migrating fish would be able to make it up stream to spawn on prime spawning habitat. Impassable barriers such as this limestone bedrock out crop made it difficult for salmon to make it upstream in the fall when water levels are lower. We created a fish ladder to help pass this barrier, restored some bank erosion and created fish habitat by placing gravel and boulder clusters. Thank you to RFCPP, NOHFC, Georgian Bay and Lake Huron Framework for Community Action funding, MNRF -COA, Manitoulin Transport and the Salamander Foundation for supporting this project!
