Partygoers apparently hoping to catch a glimpse of nude sunbathers crowded on one side of a floating barge, prompting the ship to capsize and dump all 60 people into Lake Travis. The accident occurred during Splash Day, a semiannual event hosted at the clothing-optional area. Witnesses said that all of the people aboard the barge moved to one side as it neared Hippie Hollow, creating uneven distribution and making it tilt. It sank in 50-foot-deep water.
