Eurasian Watermilfoil

Currently not present in La Plata county. Eurasian watermilfoil is usually found in slow moving water areas. Eurasian watermilfoil starts spring growth before other native aquatic plants making it very invasive.  The plant forms very dense mats of vegetation on the surface of the water that interferes with power generation and clogs water intakes.  These mats also interfere with recreational activities and creates a mosquito habitat and reduces native vegetation.

There are native Watermilfoil species in Colorado, check out a Colorado Parks and Wildlife comparison chart to see how they are different from the invasive Eurasian variety.

For more info and how to control, check out the Colorado Department of Ag Fact Sheet
