No matter how hard we might try, we cannot improve on nature. This small water control structure is just one of many that have been successfully engineered by Beaver Construction Inc. This industrious group construct, operate and maintain a network of small dams that provide an important flood mitigation service during the annual spring thaw in the Canadian Rocky Mountains. They ask nothing in return except to be left alone to do what comes naturally.
Mother always did know best. Nice image, as well.
