Cool, cloudy summer stopped milfoil growth

Kelowna Daily Courier – January 30, 2020

Wintertime weed-harvesting efforts now underway along Kelowna’s beaches haven’t turned up many thick patches of Eurasian milfoil.

A relatively cool and cloudy summer in 2019 hindered the growth of the slimy lake weed, officials with the Okanagan Basin Water Board say.

“We haven’t notice any particularly bad areas in Kelowna so far this winter. Last summer was relatively mild for milfoil growth likely because the weather was somewhat cool, cloudy, and rainy,” James Litttley of the OBWB said Thursday.

“Milfoil thrives in very clear, hot conditions when there is not a lot of rain to reduce water clarity,” Littlley said.
