RedactedNarrative: On July 21, 2017, at approximately 4:58 PM, agents were dispatched to Lake Verret in Assumption Parish in reference to multiple sunken and damaged vessels, due to a severe storm that passed through.  After further investigation, agents learned that a 54' houseboat LA 5756 FJ  was on anchor with a 25' aluminum center console LA 1061 FJ secured to the houseboats port side. When the severe weather passed through the two anchors of the houseboat broke loose causing the vessel to drift towards a group of three other houseboats. 
  
  The owner of the houseboat attempted to start the engines but was unsuccessful. At that time, one of Operator1's friends boarded his vessel which was tied to Operator1's houseboat and started the engine. Operator1's friend began using his vessel to try to keep the houseboat from colliding with the group of houseboats but the lines popped. Operator1 was then able to start the houseboat motors. When the motors started the propellers became tangled in the anchor lines and then became disabled and unable to maneuver the houseboat. 
  
  The houseboat and center console vessel turned sideways into the oncoming waves. At that time, LA 1061 FJ, rolled under the houseboat. The houseboat continued drifting, pinning, and sinking as 18.5' aluminum vessel LA 7010 EX. Operator1's houseboat then collided with the group of 3 houseboats causing damages to the sterns and motors on all 3 houseboats. All 4 houseboats involved, sustained damages to the roofs and decking. 
  
  The two aluminum vessels that sank were recovered and sustained minimum damages. S.A. was able to verify that 1- juvenile donned a Type III PFD when the weather began to worsen. No other PFD's were used at the time of the incident and agents do not suspect drugs or alcohol to be contributing factors in this incident.
