From email from Denver Water (Stacy Chesney):
In the interest of public safety, Waterton Canyon will be closed to public access Friday, July 6, to allow the U.S. Forest Service to work the Mill Gulch Fire, a small three-acre fire, on U.S. Forest Service land in Douglas County.
According to the U.S. Forest Service, lightning sparked the fire around 4 p.m. today, approximately 4.5 miles from the bottom of the canyon on a ridge. Local jurisdictions responded with hand crews, engines and helicopters to help contain the fire. The U.S. Forest Service expects to have the fire contained by morning. The canyon will remain closed all day Friday as crews work to ensure the fire is mitigated.
The canyon is expected to be open this weekend, but further details will be provided Friday afternoon.
For question on the fire, please contact Cathleen Thompson, U.S. Forest Service, at 707-853-4243.
