Pittock Dam is a gravity dam located in Woodstock, Ontario, Canada. The structure spans the main branch of the Thames River, forming the Pittock Reservoir, an artificial lake that delineates the northeastern boundary of the City of Woodstock.
Purpose and Operation
The dam was constructed primarily for flood control and flow‑augmentation. By regulating water releases, it improves downstream water quality during dry summer periods and provides year‑round flood protection for communities situated downstream on the Thames River.
Construction History
Construction of Pittock Dam began in 1964 and was completed in 1967. At the time of completion, the total cost of the dam and its associated land acquisition was approximately $6 million (Canadian dollars). Ongoing maintenance expenses are estimated at about $40,000 per year.
Reservoir and Conservation Area
The impounded water forms the Pittock Reservoir, which serves both functional and recreational roles. The surrounding Pittock Conservation Area consists of a narrow strip of land on either side of the reservoir, offering public access for activities such as hiking, canoeing, and wildlife observation.
Management
The dam and reservoir are overseen by the Upper Thames River Conservation Authority, which is responsible for water‑resource management, flood mitigation, and environmental stewardship within the Thames River watershed.
Related Infrastructure
Pittock Dam is one of several flood‑control structures on the Thames River, alongside facilities such as Wildwood Dam (near St. Marys) and Fanshawe Dam (near London).
