RedactedNarrative: On August 11, 2016 at approximately 1330 hours I reported to the scene of a sinking boat at the back of Hall's Creek Bay, on Lake Powell within Glen Canyon NRA. Upon arriving on scene I witnessed a beached/anchored 57 foot houseboat named Swift Escape, that was taking on water from the stern end, The entire stern/swim deck of the boat was submerged in water which was also flooding into the interior cabins of the vessel. Upon approaching the sinking houseboat I contacted the boat operator.
  
  According to OPERATOR, on August 10, 2016 at approximately 1600 hours a large storm came through Hall's Creek Bay in the area of where the houseboat was anchored. The vessel Swift Escape was currently occupied by OPERATOR along with his family and friends when the heavy winds and large waves began to move the houseboat from its anchored position near shore. At the start of the storm the houseboat was secured to shore by five anchors, two to the west, two to the east, and one centered. As the winds began to increase and waves grew to an excess of four feet, two of the anchors broke free from shore, causing the houseboat to move east. Large waves began to swamp the stern of the boat and flood the engine compartment. The storm lasted two hours and once it ended at approximately 1800 hours, the houseboat had moved twenty feet to the east with the stern submerged by water that began to flood the interior of the houseboat.
  
  The storm had caused significant damage to the outer and interior sections of the houseboat. Damage witnessed and documented at the time of my investigation are as follows. Outer damage: Destroyed railing of the starboard side, submerged swim deck, flooded AC unit located on stern. Interior damage: Flooding caused significant damage/destruction to the engine compartments, soaked carpets, water damage to bedrooms/mattresses and storage compartments. Due to the excessive flooding of the interior. It is also probable that electrical units within the houseboat were also damaged.
  
  Statement: operator
  We were playing cards on the front when the winds picked up and we decided to stop playing. We had 5 anchors, 2 west, 2 east, and one centered. As the wind increased the center anchor broke out of the rock. This caused the houseboat to start pushing east. The wind was coming directly from the west, perpendicular to the boat. We then unhooked the two ski boats from the houseboat and at that time another anchor stake broke/bent out of the rock. This caused the boat to move even further to the east. At that point the waves were so big they were coming over the back swim platform and into the engine bays at a rate that bailing out the water was useless. The storm lasted for 2 hours and by the time it had calmed the back of the boat was 24" under water and had moved 20 ft. onto shore.
