Monroe News is reporting that the city of Monroe, Michigan is making plans to wash out the invasive flowering rush (Butomus umbellatus) that has taken over parts of the River Raisin. If all goes well, local dams will be opened up next spring, with the goal of lowering the water level and increasing the rate of water flow. Officials are hoping the rush will find the new growing conditions unpalatable, and are also looking forward to the benefits removing the dam gates should have on fish populations. As a contingency plan, volunteers will also be recruited to do hand-pulling.
