RedactedNarrative: Operator of vessel 1 along with 6 passengers were near the dam at Lake Pueblo State Park. The water was calm and they were wake surfing for approx. 30 minutes when they noticed the wind start to pick up. They started to empty their ballast tanks as they headed toward shore. As they headed back, the added weight of the water in the ballast tanks and the heavy wave action caused the vessel to swamp and eventually capsize. All 7 people ended up in the water and all had PFDs. They were eventually picked up by another boat.
