Friday morning the New Orleans Fire Department was called to 8000 Lakeshore Dr. to investigate a red oily sheen in Lake Pontchartrain near Landry's Restaurant, according to a NOFD press release.
Around 8 a.m. the NOFD confirmed the presence of an oily substance and requested the Hazardous Materials Unit (Haz-Mat) be called to the scene.
It was estimated that the oily substance covered an approximate 2 square mile area.
Members of the NOFD Haz-Mat unit tested a sample of the substance and were able to identify is as diesel fuel.
The United State Coast Guard (USCG) and the National Response Center were notified of the possible spill and were dispatched to the scene.
It was determined that the fuel came from a docked 73ft recreation boat having maintenance done while docked in the New Basin Canal.
