Stewart Lake Causation Study

Muskoka's residents and District Council care about water quality. This important topic impacts the environment, economy, and desirability of the District as both a place to call home and a destination. In an effort to enhance water quality and resident/visitor experience in Muskoka, the District is undertaking causation studies on lakes considered as vulnerable from a water quality perspective. One of these causation studies will be on Stewart Lake.

Stewart Lake is 1.52km2 in size and is located in the Township of Georgian Bay and Township of Muskoka Lakes. The lake experienced blue-green algae blooms in 2010 and 2011. This led to the lake being classified as vulnerable in Schedule E2 of the Muskoka Official Plan (MOP). As outlined in the MOP, when a lake is listed as vulnerable, a waterbody-wide causation study should be initiated to determine the causes and relative contributing factors which lead to the identified water quality indicator, as well as to produce recommendations and mitigative actions that can be taken by stakeholders, the District, and others to ensure water quality may be enhanced in the long-term.
