 Muskoka River Water Management Plan





The goal of water management planning is to contribute to the environmental, social and economic well being of the people of Ontario through the sustainable development of waterpower resources and to manage these resources in an ecologically sustainable way for the benefit of present and future generations.

Local waterpower companies (Ontario Power Generation, Orillia Power Generation Corporation, Algonquin Power Fund Inc. and Bracebridge Generation Ltd) worked with the Ministry of Natural Resources to develop a water management plan for the Muskoka River watershed. The Muskoka River Water Management Plan (MRWMP), which was implemented in 2006, takes an ecosystem-based approach to water management by considering the interests and concerns of all water users within the watershed (e.g. fish, wildlife, navigation, hydro generation, recreation, flood control etc.).

 The Muskoka River Water Management Plan includes:

Muskoka River Water Management PlanOperational plans for each waterpower facility or water control structure (dam)

Legally enforceable provisions for the management of flows and water levels

Compliance monitoring to ensure that waterpower industry facilities are meeting the requirements of the plan

Effectiveness monitoring program to determine whether the implementation of the plan results in the anticipated ecological and social improvements.
