Eurasian Watermilfoil, an aquatic invasive plant species, detected at Reservoir

Colorado Parks and Wildlife has confirmed the presence of Eurasian watermilfoil (EWM), an invasive plant, in the Boulder Reservoir during a semi-annual invasive species monitoring visit. If it becomes established, EWM grows quickly, forms thick mats and disrupts aquatic ecosystems.
