RedactedNarrative: On September 6, 2015 at approximately 2:15 I (Cpl.) heard Ofc. contact DNR dispatch in reference to a vessel that had sunk at the Assateague State Park Boat ramp. The vessel had been involved in a boating accident in the Chincoteague Bay near marker 39. I responded to the scene by vessel along with Cpl.. Upon arrival, I observed a 25ft Grady White bearing a MD registration of 1958 BF sitting on the bottom of the ramp listing to it's starboard side. I made contact with the operator/owner. 
   
  Operator advised that he was underway in the Chincoteague Bay when he struck a hard submerged object in the channel near marker 39. He advised that the vessel started taking on water so he quickly tried to make it to Sunset Marina. He advised as he was going he was taking on so much water that he would not be able to make it to Sunset. He elected to bring the boat in to Assateague State Park where the boat sunk on the ramp. While inspecting the vessel I noted a strong odor of gasoline and observed a sheen in the water. I contacted Worcester Central to have the Berlin Fire Department respond for the gas leak. Operator advised that he had filled the tank up earlier in the day and estimated that the tanks had over 100 gallons of unleaded gasoline. Berlin Fire and Worcester County Emergency Services Personnel responded to the scene. They placed booms around the vessel to trap any fuel that was leaking. Racetrack Auto was contacted by the owners who responded to the scene with a rollback and an additional tow truck. Once the vessel was removed from the water I was able to observe heavy damage to the hull of the vessel consistent with a collision with a hard object. Cpl. transported Operator back to the scene of the collision to get a better location and attempt to locate the submerged object. Cpl. advised that there were dredge pipes in the area but no visible markers or pipe in the channel where the collision occurred. The vessel was removed from the scene by Racetrack Auto. On September 7 I was contacted by Cpl.. He advised that Marine Diver Services had been hired by Operator to scan the area. 
   
  He advised that Diver had located a large section of unmarked dredge pipe in the channel where the collision occurred using side scan sonar. I contacted the United States Coast Guard (USCG) Station Ocean City as well as USCG sector Baltimore to request that they mark the area as well as put out a notice to mariners. I was told that the crew that marks hazards would not be available until Tuesday. I also requested that this information be forwarded to their commercial enforcement division since the dredging operation is a commercial operation contracted by the United States Army Corps of Engineers (USACE).
   
  On September 8 I spoke with Diver. He confirmed that there was several hundred yards of unmarked dredge pipe in the area that was within the navigational channel at marker 39. He sent me an email with the coordinates with the locations marked on a chart as well a pictures of the side scan images (ATTACHED). I am also a member of our agencies under water operations unit and have been trained on the use and how to read images of a side scan sonar. I am also familiar with the dredging operation that have been occurring in the area. After viewing the side scan images I can conclude that the images do show dredge pipes. I again contacted the USCG station Ocean City and spoke with Duty Officer. He advised that they had also received the report and that they had forwarded the information to USCG sector Baltimore and the USACE. I made contact with Operator by telephone. He advised me that he was still waiting on estimates of the damage to the vessel but was guessing that the damage would be around $18,000. He also confirmed that he had hired Diver and had been briefed on the report. The severity and location of the damage is consistent with a hard impact with a solid object that was partially submerged. The only items on the side scan imagery taken
