Vail Daily reports that an algaecide known to be toxic to fish entered Mill Creek this week. Colorado Parks and Wildlife recorded 120 dead fish Tuesday in Mill Creek and Gore Creek in Vail. The Eagle River Water and Sanitation District noted abnormally high water usage over the weekend from a storage tank at Golden Peak, whose primary user is Vail Resorts. After being contacted by the district, Vail Resorts found that a few isolation valves on its snowmaking setup had been left open. The valves for the snowmaking setup were shut last week, which has stopped the discharge. The Colorado Department of Public Health and Environment stated that the risk of health impacts on humans and dogs that may have been in the area are expected to be low.
