At approximately 12:01 pm on April 27, 2021, a tanker truck carrying 8,500 gallons of gasoline was involved in a rollover accident on Highway 36 (near Mile Marker 18) northwest of Lyons, Boulder County, Colorado. The tanker spilled an estimated 1,000 – 1,600 gallons of gasoline at the site. The spilled fuel traveled west along a drainage ditch and into a culvert that discharges to the North Saint Vrain Creek. It is unknown how much of this release entered the creek. A fish kill was also observed in North St. Vrain Creek downstream of the spill site, as a result of the release.
