Green Mountain Reservoir is Free of Invasive Mussels

After three consecutive years of negative testing, state and federal officials removed Green Mountain Reservoir from the positive waters list for quagga mussels. This de-listing makes Colorado a completely negative state for both zebra and quagga mussels.
