Paul Koch woke up one morning last month and peered out his kitchen window to find a trespasser taking a dip in their backyard pool.

“I called my wife and said, there’s a moose in the pool!”

Koch said the 800 lbs female swam a few laps and then stood calmly in the shallow end for several hours. He called police, who watched as the moose eventually made her own way out of the backyard.
