Leonard Lake Causation Study

RiverStone Environmental Solutions Inc. was retained in February 2021 by The District Municipality of Muskoka (DMM) to undertake a Causation Study for Leonard Lake in response to recent cyanobacteria blooms and to the updated water quality policies in the Muskoka Official Plan.

The Leonard Lake Study results were delayed until November 28, 2022 and at that time a meeting was held by the DMM and Riverstone to present the draft study findings. 

The Riverstone Leonard Lake draft report was posted on the Engage Muskoka website December 8, 2022 and can be accessed through the Riverstone Causation Draft Study button below.

After careful and thoughtful review of the Riverstone Causation Draft, LLSA presented a summary of issues which LLSA felt required further attention. The full LLSA critique along with a cover letter were sent to the DMM January 10, 2023. The LLSA paper and cover letter (below) were prepared by the Leonard Lake Water Team and LLSA board members.
