Water Levels

Water levels on Lake Weslemkoon are maintained by the Ministry of Natural Resources and Forestry (MNRF).

The 2017 cottaging season was a challenge with all of the rain – cottagers experienced high levels for much of the early spring, causing flooding of some boat houses and docks. The MNRF does their best to follow the planned Water level Management Plan but are often constrained by how much water they can release from the lake as too much would damage the infrastructure downstream of Weslemkoon.

LWCA Director Mark Warlow stays in regular contact with the MNRF, communicating any concerns about high water levels.

During September and early October dam repairs were done – specifically to remove the cofferdam and formwork, then pour replacement concrete. This job was done without any impact to the water level on the lake.

The dam, located at the North end of the lake, was originally built in 1953. It maintains the lake at it’s historical springtime high level; about 6-8 feet above its pre-dam summer low level.
