Dam Safety

We care about your safety and ask that you take great care if you find yourself near Yukon Energy’s dams, hydro plants and control structures.

• Water currents are strong.
• Water levels can rise rapidly without warning.
• Water near hydro plants has a strong undertow.
• At the Lewes River Control Structure, always use the boat lock when travelling by watercraft. NEVER try to pass through the control gates.

Yukon Energy has installed safety features at the Whitehorse Dam and the Wareham Dam in Mayo.

A horn will sound whenever the gate is rising at either dam. This serves as a warning of a sudden increase in river levels due to water being released through the spillways.

At the Whitehorse Dam, a red flashing light may also be activated.

If you hear the horn or see the flashing light, please move well away from the water’s edge.
