Arvada Reservoir

On Monday, July 11, Arvada Reservoir will be closed for the treatment of milfoil, a noxious weed that has become pervasive throughout the Colorado Front Range. Arvada Reservoir has not had milfoil mitigation since 2012. This year, about two-thirds of the shallow shorelines surrounding Arvada Reservoir are infested with the weed. As Arvada Reservoir is first and foremost a drinking water supply, we must ensure safe, treatable and good-tasting water. Guests to the reservoir may continue fishing the following day.
