What happened
The episode as NWS VEF wrote it up.
Damaging winds and severe flash flooding ripped through the western part of Lake Mead. Las Vegas Bay Marina's service dock and main access dock were blown apart resulting in approximately 100 gallons of fuel spilled. Callville Bay Marina also sustained substantial damage from the winds. Flash flooding washed out all approved roads near Callville Bay and produced major erosion around culverts along a section of North Shore Road. Washes between Las Vegas Bay and Callville Bay were filled bank-to-bank with up to 16 feet of water. 30 people at Boxcar Wash (near Callville Bay) were temporarily stranded and had to be rescued by Park Rangers due to flash flooding.
