Spill operations have ended at the WAC Bennett and Peace Canyon dams.

Spills began last week due to greater than anticipated inflows into the Williston Reservoir during the record-breaking heatwave.

BC Hydro said Tuesday spills ended around 1:45 that afternoon as inflows to the reservoirs have decreased. The reservoir elevation was reported at 669.69 metres, or 2197.1 feet.

"Flows from Peace Canyon Dam have dropped as a result of ending the spill and will be about equal to the output of three of the four units," said spokesman Bob Gammer.

"It is possible that weather and/or unit maintenance may cause a resumption of spilling at some point during the summer. We will notify you if that occurs."
