The William Fire started on September 6, 2020 at approximately 14:00. The fire was caused by target shooting. Due to hot weather and strong winds the fire spread rapidly and doubled in size over a few days. Snow and rain moved into the area September 8, 2020 bringing cooler temperatures which dramatically decreased fire behavior. As warmer and dryer weather conditions return fire behavior is expected to increase to moderate. The fire is being manged by Great Basin Team 3, a Type 2 incident management organization.
