Images of the event show the water of Lake Travis choppy with the wakes of dozens of boats flying American, Texas and “Trump 2020” flags. Dark said that weather on the roughly 19,000-acre (7,690-hectare) lake was calm, but that the tightly packed boats created large waves in areas. Deputies have found no evidence of foul play, she said.
The first call for help came at 12:15 p.m., and later distress calls were for boats taking on water, stalled engines and capsizing, Dark said. Three of the boats that sank were towed to shore, while the other two were still at the bottom of the lake, she said.
Austin-Travis County Emergency Medical Services received no calls for service related to the parade, a spokeswoman said.
