In the middle of the hottest weekend of the year, beaches along Okanagan Lake in Vernon have been closed. 

The city said Saturday afternoon that all beaches along the southeast arm of the lake, from Kin Beach to Paddlewheel Park, are temporarily closed due to a sewer line break in the Okanagan Landing area. Crews are currently controlling and repairing the sewer line.

The city said the broken sewer line is adjacent to waterways with the potential to enter them and is closing the beaches out of caution to safeguard people from exposure to "high bacterial counts."

"Beaches within the proximity of the break will be temporarily closed until testing can confirm water quality is an acceptable level," the city said.

Signs have been posted at the affected beaches advising that swimming is not currently recommended.

"The water quality for the beaches will continue to be monitored and the public will be advised when it is safe to resume swimming in the area," the city said.
