RedactedNarrative: On 6/06/2020, at approximately 6:00 PM, Maryland Natural Resources Police was on marked patrol of Deep Creek Lake on vessel NRP806. I was patrolling the lake south of the Glendale Bridge when I saw a disabled vessel, white and blue in color near the west shoreline. The operator of the boat was waving me down. The owner/ operator of the boat, later identified by his Maryland Driver’s License as OPERATOR 1. OPERATOR 1 stated he had just picked his boat up from repair shop. I tied off to OPERATOR 1's boat, a blue and white Cobalt with registration MD3616CS. OPERATOR 1 stated he was riding around the lake when the check engine light came on, he heard a pop sound and smelled smoke. As OPERATOR 1 was explaining this to me, flames started coming out of the back deck engine compartment. OPERATOR 1 was unable to retrieve his fire extinguisher because of its location to the fire. I retrieved the fire extinguisher from NRP806 and instructed OPERATOR 1 to use it on the fire as I lifted the hatch. The fire was extinguished but there was still smoke coming from the forward console. I instructed OPERATOR 1 to put on his life jacket and helped him aboard NRP806. Due to the continued smoking, I requested the assistance of the Deep Creek Fire Department through Maryland Natural Resource Police dispatch. While waiting on the fire department to arrive, Maryland Natural Resource Police arrived on marked patrol vessel NRP881. At this time OPERATOR 1’s boat had stopped smoking and another MNRP went onboard and found gas in the bilge area along with several melted hoses and wires. The Deep Creek Fire Department arrived on the scene shortly after and declared it safe to transport. With OPERATOR 1 on board, I towed his vessel to repair shop customer docks. OPERATOR 1 was then transported to his dock by another MNRP officer. All events occurred in Garrett County, Maryland.
