Vehicular gates will be closed for the remainder of the event, which began on Aug. 27 and was scheduled to end on Monday, according to the U.S. Bureau of Land Management, which oversees the Black Rock Desert where the festival is being held.

The vehicular gates were closed for the remainder of the event, a decision taken by the U.S. Bureau of Land Management and the Pershing County Sheriff's Office. There were reports of one death at the festival and authorities are investigating the incident. Despite the harsh conditions, festival attendees were seen making the best of the situation. 

The festival, which began on August 27, 2023, and was supposed to end on September 4, 2023, saw over 70,000 attendees stuck due to the flooding. To aid attendees, festival organizers provided mobile cell trailers to boost cell service and charging stations around the festival grounds. They also worked on providing medical resources and public Wi-Fi access. 

Notably, many attendees, including celebrities like DJ Diplo, were seen leaving the festival by hitchhiking or walking through the mud. The floods led to a flurry of social media activity, including both messages of support and unsympathetic jokes. The President, Joe Biden, was also briefed on the situation at the festival.
