SREL has kindly posted the Muskoka River Watermangement Plan on their web site.
The document is hundreds of pages, but some pages of particular interest are:
- A schematic diagram of all the dams in the entire Lake Muskoka watershed is here. This shows the complexity of coordinating the flows through all the dams.
- Acres International authored the report, and they set up a computer simulation of the water flows, and a summary diagram of the information input to this simulation is shown here.
- A map showing the Lower Muskoka Sub-watershed is here.
- Among other things, the water management plan defines Normal Operating Zone for the water levels, for all lakes and rivers, throughout the year. A summary of the terms used is here.
- Maintaining the water levels is complex because the flow rates vary widely throughout the year. A summary is presented here.
- A description of the situation is here. During the summer, it allows a normal range variation of 18.5 inches.
