Characterization of the ice regime at Les Marais pool, Causapscal River

Recipient: Corporation de gestion des rivières Matapédia et Patapédia 
Approved Amount: $10,000

In 1982, there was a decline of salmon in Causapscal River. Two barriers were installed (1983) at Les Marais pool. From 70 spawners, there are now approximately 600. The pool serves as a protection against poaching. Severe erosion has created secondary breaches which deflected the flow and altered the pool.  It is a critical situation.  In 2017, with funding from CN, a 40 m section of the bank was stabilized. To continue stabilizing activities the ice regime (and its strength) must be characterized. This characterization is required to ensure that the bank stabilization projects will last at least 50 years. The ice dynamics study is a prerequisite of MDDELCC and CEHQ for legal environmental approval and continuation of bank and habitat rehabilitation to ensure salmon protection and conservation at Les Marais pool.
