In the Aberdeen-Springfield canal system, Butomus umbellatus has colonized an estimated 150 miles of the 300-mile main canal, threatening water availability for potato and cash crops and requiring removal every 2 or 3 years. Full management of flowering rush in this canal system could raise costs to farmer shareholders by as much as 8%.
