Fairy Lake

Fairy Lake is located in Acton at the headwaters of Black Creek adjacent to Prospect Park and Rotary Park surrounded by residential properties. The lake is adjacent to rural lands, a campground/trailer park, and natural open space.

The lake originated in 1830 when the Adams brothers built a dam on Black Creek to create a mill pond in order to operate a flour mill and a saw mill. Prior to the creation of the lake, the area was a wetland. Today, the dam remains in place and maintains the water levels creating the ‘lake’.

Fairy Lake is approximately 26 hectares and is used for boating, swimming and fishing providing scenic views from various vantage points.

The Town has undertaken various studies of the Lake over the years; most recently the Fairy Lake Water Quality Study completed in 2010. The Study as well as additional information about Fairy Lake can be found on this site as well as on the Town's web page.

June 2021 Update:

The update of the Water Quality Study has begun. A consulting team lead by LGL Limited, will be conducting water quality related studies on the lake and the surrounding shoreline beginning in June 2021 and extending through to the spring of 2022.

The focus of the field studies will be to collect information about wildlife use and vegetation communities, and to collect water and sediment samples. These studies will be conducted on foot or by motorized boat on lands owned by the Town, and on private property where access has been granted.

The community will have access to a presentation of the Fairy Lake Water Quality Study results later in the study prior to the final recommendations being made to Council for the ongoing management of the Lake.
