HWY 36
Lyons, CO 80540

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. 

EPA, Boulder County Public Health, and LMH Environmental, a consultant for the insurance company, understand that residents are concerned about their water wells.  If you have concerns, please contact LMH at rmuldrew@sbcglobal.net.

Colorado Parks and Wildlife is assessing the fish kill and other wildlife issues as they arise.   Please contact Colorado Parks and Wildlife at LyonsFishInfo@state.co.us with any photos or videos of dead fish, or if you collected and saved dead fish.
