Investigators will be on scene again Thursday working to determine cause and origin of the blaze.

A state fire marshal has been called in to help investigate a condominium fire in Osage Beach Wednesday morning.

According to a press release from the Osage Beach Fire Protection District, assistance from the state office was requested after initial investigation by their own fire marshal. Investigators will be on scene again Thursday working to determine cause and origin of the blaze.

There were no injuries to occupants of Lake Chalet, the seven-unit apartment building that was destroyed by the Sept. 20 fire just west of the Grand Glaize Bridge in Osage Beach.

At 9:54 a.m., the OBFPD was called to a commercial structure fire at 962 Chateau Lane in Osage Beach. First arriving unit found heavy fire involvement on the backside of the structure. Crews advanced hose lines from both sides of the building in an attempt to keep the fire from spreading while waiting for mutual aid crews to arrive and establish water supply. 

This development had no city water or hydrants on the property and lines from the closest hydrants a block away had to be stretched across the highway, causing the closure of Osage Beach Parkway for several hours.

The buildings sustained heavy damage and are considered a total loss.

Lake Ozark, Mid County, Sunrise Beach, Gravois, Rocky Mount and Eldon fire departments, Osage Beach Ambulance, Osage Beach police and Mercy Ambulance assisted OBFPD on the scene.

One firefighter was transported from the scene to Lake Regional with heat exhaustion; a second was treated for a back injury after the fire was under control. Both firefighters have been released after treatment.

The scene was cleared about 2:30 p.m.
