Coeur d'Alene, ID -

Labor Day Weekend is the unofficial end of summer and summertime fun so that can only mean one thing when it comes to Lake Coeur d'Alene.  It's time for Avista to pull the plug.

The power company's annual draw down of the lake to prevent winter time flooding will begin on Tuesday, September 6th.  But don't look for any spectacular spilling of water at Avista's Post Falls dam.  Instead, listen for the hum of the generators cranking up the power to move the water out of the lake.

"All the water that leaves the lake is used to produce electricity at our dams on the Spokane River," said Avista spokesperson Mary Tyrie.

By the end of September, the level of the lake will have dropped by one foot.  To put that into perspective, that is 13.83 billion gallons of water that will leave the lake and begin flowing to the Pacific Ocean.

The lake will continue to drop one and a half feet per month until it reaches its natural winter level which is about six feet below summer levels.
