The French River Dam Complex-Big Chaudière Dam Replacement
The French River is part of a vast watershed in Ontario that drains Lake Nipissing into the Georgian Bay. Public Works and Government Services Canada (PWGSC) is responsible for managing water levels within the standard operating guidelines for Lake Nipissing and the French River.
The French River Dam Complex is made up of three dams: the Big Chaudière Dam, the Portage Dam and the Little Chaudière Dam. These structures control the outflow from Lake Nipissing and are essential because they help maintain the water level of Lake Nipissing (city of North Bay) and regulate the flow of water into the 105-kilometre-long French River.
The Big Chaudière dam was built between 1910 and 1916 and consists of two concrete structures with large steel gates that are divided by a rock island, thus forming two channels, a north channel and a south channel: a twin gate structure controls the flow to the North Channel and a single gate structure controls the flow to the South Channel.
While the Big Chaudière Dam is structurally safe, it is now nearing the end of its useful life. The replacement project will allow for continued safe and reliable water management and will bring the dam in line with the Canadian Dam Association guidelines.

Scope of the activities
The general scope of the Big Chaudière Dam Project is as follows:
- Construct new North and South dams close to the existing ones; and
- Remove the existing North and South dams.
In the spring of 2012, PWGSC proceeded with a Request for Proposal for an engineering design consultant for the replacement project of the dam. This process was conducted in a fair, open and transparent manner through the Government Electronic Tendering System (MERX). On June 15, 2012, PWGSC awarded a $717,997.48 engineering design contract for the replacement of the Big Chaudière Dam to Hatch of Niagara Falls, Ontario. The contract was competitively awarded and will provide engineering design services as well as preparation of construction drawings and specifications for the replacement of the dam. The design work is expected to be completed in summer 2013. PWGSC will then solicit bids for the construction work, which is expected to begin in summer 2013 and be completed within two years.
