This reminded me of a time about 20yrs. ago. A friend of mine lived at the "Landings" apartments on N. Keystone Ave. The complex planted around fifty saplings all around the bay that is part of the White River. A few days after they finished planting the trees the beavers dropped about half of them. The quick thinking maintenance man came up with a plan to get rid of the beavers by shooting at them with a .22 rifle as they swam around in the bay. I don't think he killed any beavers but he learned why you don't shoot over water, and he sure did a number on the clubhouse across the bay. He shot out at least 1 window and a sliding glass door panel. There were also several holes in the exterior siding. There were never many people at the clubhouse so the damage wasn't noticed right away. It was rumored that the damage was caused by vandalism but my friend knew what really happened. Management got someone to trap and remove them after that incident. Eventually though, every tree they planted disappeared.
