Improving dam safety at Little Long

ROAD OPEN Public access restrictions across Adam Creek/Little Long no longer apply. The road is now open for public use.

Controlling water levels

Ontario Power Generation (OPG) is making dam safety improvements to water control structures at the Adam Creek spillway, and other nearby dams on the Mattagami River.

The Little Long Dam Safety Project has increased the discharge capacity at the Adam Creek spillway structure, located on the Little Long Reservoir in Northern Ontario. Four new sluice gates were added, as well as other reliability improvements made.

A sluice gate works like a sliding barrier that dam operators use to control water levels and flow rates in rivers.

Improving safety and generating local economic benefit

The project ensures that extreme floodwater can safely bypass OPG’s four Lower Mattagami River stations (Little Long, Smoky Falls, Harmon, and Kipling generating stations) in the event of large-scale flooding in the area. This also ensures that OPG is in compliance with updated requirements established by the Province of Ontario.

Being able to report that the project is nearing completion, on time and on budget, is a testament to the collaboration between various groups, including the OPG team, project contractors, Indigenous communities, local residents, and regulators. Once the remaining sluice gate work is complete, the focus will move to site rehabilitation phase. We will continue to manage water safely at our generating stations and control structures, in accordance with the Mattagami River Water Management Plan.

Much of the project involved heavy civil construction. This provided employment and contracting opportunities for Indigenous communities and local businesses in Kapuskasing, Smooth Rock Falls, and surrounding areas.

Construction activities are over 99% complete. Ongoing and upcoming activities include:
