BOULDER, Colo. (May 20, 2024) -- Fire crews remain at the Forsythe II Prescribed Burn Project Site, and will continue their work for the next several days. These crews are working on securing the edge around the Unit 44A burn area by spraying water and stirring dirt to ensure lack of heat while also utilizing sprinklers to widen the perimeter line. View a video from our Burn Boss, reviewing this week's work and successes.

There are no further ignitions planned for the Forsythe II Prescribed Burn project area this spring. We will continue to share any notable updates if and when they occur, and we will provide a final email notification when Forsythe II is declared completely extinguished for the season.

BOULDER, Colo. (May 17, 2024) -- Fire managers are monitoring conditions for potential ignition as soon as Sunday, May 19, on the Forsythe II Prescribed Burn Project. Ignitions continue to be contingent on having appropriate weather conditions fall within the parameters of the burn plan, such as suitable dispersal wind speeds and ignitable fuel moistures. Ignitions may also be possible on Monday, May 20. 

Since our first ignition date on April 15, fire managers have successfully treated approximately 122 acres at Forsythe II this season. Fire managers hope to treat up to an additional 70 of acres with this ignition, if conditions allow. 

There may be notable smoke visible from the Forsythe II Prescribed Burn during this burn. Residents and visitors in the area should expect to see smoke and flames when operations are underway. The following areas in particular may see and smell smoke during this burn: Lakeshore subdivision, Crescent Village, Crescent Meadows, Gross Reservoir, Walker Park Ranch, Miramonte, Wondervu, Eldorado Canyon State Park, and parts of eastern Boulder County. 

Fire managers work closely with experts to minimize the impacts of smoke to the best extent possible. Air quality is carefully monitored before and during a prescribed fire and all prescribed burns comply with state air quality regulations to minimize impacts to communities. View more information
