Langford Lake gets stirred up

On Sunday, Langford installed new aerator, which replaces an older, smaller machine that had regulated oxygen levels in the lake since 1985

First there was the noise of the Kamov helicopter, followed by the sight of Langford Lake’s massive new aerator.

Next will be the smell as the 4,627 kilogram device gets to work.

On Sunday, the city installed the aerator, which replaces an older, much smaller machine that had regulated oxygen levels in the lake since 1985.

A Kamov helicopter was contracted to haul the new aerator, which is capable of processing the entire lake every six days.

For the first few days the areas around the lake may have a slight smell of rotten eggs to them, Langford parks manager Mike Leskiw said.

The odour is caused by nutrients and gas in the water being released.

While the smaller aerator cleaned the water near the surface of the lake, the new aerator will focus on the water at the bottom of the lake.

“The bottom of the lake is where all the nutrients are,” Leskiw said.

Divers and scientists will be working on it this week.
