RedactedNarrative: On 8/7/16 vessel #1 and its occupants were swimming around the boat in a cove on the west side of Lake Pueblo. The vessel operator noticed that his boat was getting too close to the rocks. He announced that he was moving the boat and assumed that all the people swimming in the water heard him. Without checking, the operator started the boat and shifted into reverse gear. After a few seconds he heard screaming and a "thump" He turned off the boat and ran to the back where he observed a female with severe lacerations to her right leg that were caused by the propeller of vessel #1. The female victim (who was wearing a PFD) was pulled into the boat and taken to shore where she was later transported to the hospital. Citation issued for careless operation.
