RedactedNarrative: On July 14th, 2022, at approximately 1019 hours, I was notified by dispatch of a houseboat sinking that was tired to the curtsey dock at North Ramp. Dispatch informed me that owner requested Offshore Marina to retrieve the houseboat however, Offshore Marina is unable to retrieve the houseboat. 
  Dispatch informed me that the owner of the houseboat refused to have Executive Services assist with the sinking houseboat. Dispatch informed me the owner of the houseboat had left the park. Dispatch informed me that sinking houseboat was reported by Aramark to National Park Service (NPS) Concessions Management. 
  At approximately 1025 hours, I arrived a North Ramp and saw a houseboat listing to the port side tied to the curtesy dock. The houseboat was a 55-foot Bluewater Marine Kayot bearing Utah bow numbers. I asked visitors on the ramp if they were associated with or knew who was with boat. No one had identified the owner. I notified dispatch that the owners had abandoned the boat and requested Executive Services assistance. 
  At approximately 1036 hours, boat tipped suddenly more towards the port side. Fearing the houseboat was about sink and take the curtsey dock with, I untied boat from the dock. 
  Despite my attempts to hold boat to the curtsey dock. Boat drifted such that is started to obstruct boat traffic accessing North Ramp. 
  At approximately 1042 hours, Ticaboo On Lake Services assisted in pushing boat back to the curtsey dock. The boat owner of Tica boo On Lake Services stated boat "looks like it's about to go." 
  At approximately 1052 hours, Executive Services arrived with a floating crane. Executive Services attached the crane to the port aft of boat. A general manager (GM) of Aramark who oversees Executive Services, arrived. I requested from GM that boat be impounded. GM stated he needed to contact a legal advisor before impounding. GM stated he has no authorization nor verbal request the owner to assist with boat. Executive Services then disconnected their crane from boat. 
  Executive Services stated they saw boat listing at approximately 0630 hours. Executive Services stated at that time, the aft port corner was not under water. 
  At approximately 1113 hours, Executive Services moved boat further back on the curtsey dock to give more room for boat lunching and retrieve activities at North Ramp. GM arrived and stated that someone in Aramark was able to get a hold of the owner of boat. GM stated the owner was acutely aware that boat was taking on water approximately 3 days prior. GM stated needed a written approval from NPS to remove boat.
  At approximately 1127 hours, I called Deputy Chief Ranger 2. I informed Ranger 2 that a houseboat had been abandoned, is actively sinking, tied to our curtsey dock, and Executive Services wants a written approval from NPS to remove the houseboat. 
  At approximately 1227 hours, I drove to Offshore Marina. I asked Offshore Marina if they had contact information for the owner of boat. Offshore Marina gave me a phone number for the owner who was later identified as Owner by Colorado driver's license. Offshore stated they had a launch and retrieval agreement with Owner for boat however, they did not have the equipment to retrieve it in its actively sinking state. 
  At approximately 1246 hours, I called Owner and identified myself as a U.S. Park Ranger. I asked Owner what his plan for boat was. Owner stated he wanted "Executive Services to pump it out but, no one is getting back to him." I told Owner that I was informed that he told Executive Services to not 
  touch his boat. Owner stated he "never said that," "that's not true at all," and "I want them to take care of it." I confirmed with Owner that he wants Executive Services to pull his boat. Owner replied "absolutely." I asked Owner if his boat has insurance. Owner stated it did not have insurance. Owner stated he bought the boat a week earlier. Owner stated he noticed boat taking on water 2 days prior. Owner stated he would send me a bill of sale or registration documentation. 
  I contacted GM and told him I spoke with Owner and that he is willing to have Executive Services pull his boat. GM stated their communication with the boat owner had greatly improved after I had called Owner. At approximately 1333 hours, I was advised by Aramark that Executive Services has the authorization to pull boat. I called Ranger 2 and asked if he wanted me to perform an inventory on boat. Ranger 2 requested that I perform an inventory. I was then informed by Aramark that Executive Services will assist with floating boat and Offshore Marian will tow it. 
  At approximately 1440, I started an inventory or boat. The console reported 769.9 hours on the port engine and 1492.7 hours on the starboard engine. I found the following items during the inventory: 
  •	Keys in the ignition labeled 
  •	Pioneer Stereo with removable face
  •	5 sets of keys and a fuel cap key hanging above the driver's console
  •	microwave
  •	Chicago 5-gallon shop vac
  •	Sharpe black portable air conditioner
  •	Arctic Air fan
  •	Papala tool
  •	Hydroslide Pro wake board
  •	Empty Starlink box
  •	White Standard Marine radio
  •	Lowrance M68
  •	Charbroil C3rill
  •	Water slide detached on the roof
  This inventory does not include all items aboard boat. Many other items existed aboard including food, toiletries, bedding, chairs, paint cans, oils and lubricants, extension cords, mattresses, and alcohol. There was an open bottle of Apothic red wine, approximately 2/3's full in a pink cooler a couple of feet away from the driver's console. It was apparent from the state of unsecured items in, on top of and in the back of the houseboat that boat was not prepared for retrieval from the water. At approximately 1503 hours, I completed the inventory. 
  During my inventory, GM stated the ramp will need to be shut down during the retrieval operation of boat. At approximately 1441 hours, North Ramp was closed. At approximately 1553 hours, boat was pulled from the water and North Ramp was reopened to all visitors. For approximately 1 hour and 12 minutes, visitors to Glen Canyon National Recreation Area were unable to launch nor retrieve boats anywhere in the up-lake area of Lake Powell. 
  Although boat was out of the water, it was unable to leave the bottom of North Ramp until water was removed from the pontoon. So much water weight existed in the pontoon that the trailer was sagging enough to touch the ground. Holes were drilled into the pontoon to release water. 
  At approximately 1650 hours, enough water was removed from the pontoon and Offshore Marina started to transport boat to Offshore Marina. I followed in my patrol vehicle. I observed trash fly out of boat during the transport. At approximately 1711 hours, Offshore Marina stopped on HWY 276 just north of airport road. Offshore Marina personnel attempted to secure items on boat. At approximately 1713 hours, Offshore Marian continued its transport. At approximately 1724 hours, boat arrived at Offshore. 
  I watched as boat was placed on blocks at its resting place at Offshore Marina. At approximately 1810 hours, boat was placed set on blocks. I gave Offshore Marina copies of a vehicle impound report. I left the scene and returned to patrol. 
  During the incident Owner never returned to his sinking houseboat. Owner never informed NPS of his sinking houseboat, nor asked for assistance, nor asked for permission to leave it tied to the curtsey dock. On July 1sth, 2022, at approximately 1216 hours, I asked Owner via text message to send me his registration and/or bill of sale. M
