David Richardson finally had enough with the geese.
The PGA golf professional at Soldiers Field Golf Course in Rochester, Richardson was sick of fighting a hefty Canada goose population over the past three years. They left droppings everywhere, dead spots on the greens and stains on carts and cleats.
Geese had been a problem for a while in this southern Minnesota city, where a power plant once kept lake water from freezing in the winter and consequently attracted up to 30,000 of the big birds, according to some estimates. They had been at the golf course, too; up to 1,000 fed on the bluegrass from the middle of October through spring.
But for some reason, the geese started nesting along the south fork of the Zumbro River, which flows through the course, Richardson said. And once they nested, they stayed, becoming an annoyance during prime golf season.
So Richardson decided he had to do something. He started searching the internet.
"I started with 'coyote decoys for geese,' " he said. "That led me to dogs."
Richardson found Watch Dog Goose Patrol, a Roseville company that makes dog silhouettes that bounce on a spring.
Company founder Sarah Johnson said her father patented the springs to use with turkey decoys to draw tom turkeys near during hunting season. As Johnson and her father were walking around Lake Como in St. Paul, disgusted by goose droppings everywhere, they noticed that geese seemed to avoid people walking their dogs.
