From its headwaters in Algonquin Park , the Muskoka River system flows through a series of lakes which eventually flow into Georgian Bay . There are 42 water control structures (dams) within the Muskoka River watershed that are used to control and maintain water levels on the lakes and rivers throughout the watershed. Of these structures, 29 are owned/operated by the Ministry of Natural Resources and 11 are owned/operated by the waterpower industry. The District Municipality of Muskoka owns and operates one dam while the remaining structure is privately owned/operated.
Please take the time to look at the following control structure schematic and other watershed illustrations. Consider how the coordinated management of water level and flow objectives by the various partners committed to the Muskoka River Water Management Plan might influence the use and enjoyment of the lake or river you live on.
