BC Hydro advising public of potential spilling at Peace Region dams

FORT ST. JOHN: BC Hydro may begin a controlled spill at the W.A.C. Bennett and Peace Canyon dams this week, ahead of river diversion for the construction of Site C this fall.

The spring snowmelt and significant rainfall in the Peace Region has led to higher than average water levels in the Williston Reservoir. To ensure Site C construction activities can safely be conducted, BC Hydro may release water at its W.A.C. Bennett and Peace Canyon dams to maintain appropriate space in the reservoir. This may be in addition to normal generation discharge from the dams at this time of year.

Controlled spills are considered a normal part of operations and BC Hydro's dams are designed for the safe and controlled release of water. If required, spills could begin this week and last for up to several weeks, depending on a number of factors, including the weather.

The controlled spill is not expected to lead to any water management issues along the Peace River. Residents along the river – including those immediately downstream of the Peace Canyon Dam – may notice higher than normal river levels. Flows downstream of the Site C construction site are expected to be much less than what occurred during the spring snowmelt and recent rainfall events.

BC Hydro is reminding the public and recreational river users to always use caution on and around the Peace River due to changing water levels. For more information about water level advisories, visit
