RedactedNarrative: On June 26, 2015 at approximately 1310 hours Glen Canyon Dispatch received a report of a capsized vessel under tow near buoy 13 on Lake powell.
  
  At approximately 1312 hours I responded from the Padre Butte vicinity
  At approximatley 1324 hours I arrived on scene with Rangers 
  
  I immediately observed a houseboat (boat #1) afloat in the vicinity of buoy 13 towing a green ski boat (boat #2). The boat #2 was completely capsized. The keel of boat #2 was sticking out of the water approximately 12 inches.
  
  I approached the stern of boat #1  and asked the occupants if anyone was injured and if everyone was accounted for. The occupants stated that no one was injured and everyone was accounted for.
  
  I advised the driver of boat #1 to start to drive toward shore (approximately 500' to the west). I located a spot to tie boat #2 to the rock shore in approximately 40' of water. There were no sandy beaches in the area. All surrounding area was steep rocky cliff.
  
  Boat #1 approached the tie-off location and released boat #2. I secured boat #2 to shore via a tow rope in a small cove.
  
  I identified the driver of boat #1 by Utah driver's license.  HE stated the following:
  He is the owner of boat #1 and boat #2. At approximately 1300 hours he was driving boat #1 south through the Narrows at buoy 13 with boat #2 in tow. No one was on boat #2. A cabin cruiser passed creating a large wake. The wake created by the passing vessel created large waves that crested the top of boat #2 swamping it. Boat #2 then capsized. He did not have a description of the vessel that created the wake aside from it being a cabin cruiser type vessel.
  
  Conclusion:
  As a result of my investigation I have concluded the following:
  
  At approximately 1300 hours boat #1 was towing boat #2 in a southerly direction through the Narrows near buoy 13 when a passing boat created a wake causing boat #2 to become swamped and subsequently capsized.
  
  Contributing factors to the cause of the accident were:
  1) Congested waters: Buoy 13 in the Narrows is a main thoroughfare for uplake and downlake travel to and from the Wahweap and Antelope Point marinas (the busiest marinas on Lake Powell). The channel is approximately 800' wide with steep cliffs on both sides of the channel. Vessel traffic in the area at the time of incident and investigation was very busy with vessels traveling back and forth continouosly.
  
  2) Hazardous waters: Buoy 13 is located within the Narrows, and aptly named section of Lake Powell where the channel is approximately 800' wide with steep cliffs on both sides of the channel. Rough water and large wakes are common, substantial, and long lasting in this area due to both sides of the channel being steep cliff shore.
