RedactedNarrative: On 7-22-2021   V1 operated by O1 was pulling a wakeboard skier out in front of the dam on Angostura Reservoir.   V1 was traveling west toward the dam then made a turn to the south east.  V1 then came to a crunching abrupt stop.  O1 looked back and observed that skier was not injured or in danger.  O1 then noticed the boat had come to rest on submerged rocks.  O1 emptied ballasts and then O1 and several passengers exited the boat and pushed the boat off the rocks.  O1 was able to limp V1 towards the Shep's Canyon Boat Ramp where the boat was loaded on the trailer.  O1 then noted the damage from impacting the rocks.
