Townline Creek

Townline Creek originates from springs above the Niagara Escarpment brow in the south-east edge of The Town of The Blue Mountains. From the brow to Blue Mountain Resorts’ South Base Lodge, it is heavily forest covered. The stream bed is rock and gravel and has few areas where it runs through open lands on the ski hill. It flows through Blue Mountain Resort in an easterly direction and through Monterra Golf, exiting at County Road 21 (Osler Bluff Road) just south of Monterra Road. From there it runs north along the ditch on the east side of Osler Bluff Road flowing through the westerly edge of the Provincially Significant Silver Creek Wetland Complex before discharging into Nottawasaga Bay within the Town of Collingwood.

The Watershed Trust, in partnership with the Grey Sauble and Nottawasaga Valley Conservation Authorities, has monitored the surface water quality in this creek since 2007. The purpose of this program is to measure water quality in Townline Creek and identify potential impacts of existing and future developments in the Creek’s watershed and make recommendation to mitigate identified impacts. Water quality in the Creek is compared to Silver Creek as the proximity to this Creek provides a reasonable reference to a stream of known high quality.

To date results have indicated that total phosphorus (TP) and total suspended solids (TSS) are parameters of concern and exceed Provincial Water Quality Objectives (PWQO).

The Watershed Trust has met with Blue Mountain Resorts and their engineers in 2010 and 2011 and discussed the findings of the monitoring program. Field investigations have been made and the most probable cause of the high levels of TP and TSS is recent construction activities near the South Base Lodge, as the Mountain Road/ Grey Road 19 roundabout, east parking areas and infrastructure rehabilitation in the residential community just north of the lodge all have been constructed within the last three years.
