Site C diversion tunnels opened on Peace River

Site C diversion tunnels opened on Peace River
BC HYDRO — A worker inspects a diversion tunnel for the Site C Dam project in Fort St. John, B.C.

FORT ST. JOHN, B.C. — This month, crews at the Site C Dam project opened the gates to two diversion tunnels on the north bank of the Peace River.

The tunnels, each approximately 750 metres long and 11 metres in diameter, will be used to divert a portion of the river while crews build an earthfill dam across the main river channel.

BC Hydro officials reminded boaters and other river users to stay away from the area due to the powerful river current pulling into the diversion tunnels.

A two-kilometre section of the Peace River around the Site C dam was closed to boaters this June when a debris boom was installed across the main river channel.

Earlier this year, crews began placing a rockfill berm across the river to seal off an area for the dam to be built on dry land, while keeping the water flowing through the tunnels on the north bank.

BC Hydro officials advised that river conditions will likely change over the next few months without warning and river users should use caution.

The Peace River will be diverted until the completion of the Site C dam, at which point BC Hydro will close the diversion tunnels and water will flow through the generating station and spillway.
