Decker was foremen of a construction gang along this section of the Collins Overland Telegraph - a telegraph line constructed through the interior of the province in the mid-1860's intended to establish a communications link between Europe and North America; the project was abandoned when an underwater cable was successfully laid across the Atlantic Ocean.

"Stephen 'Steve' Decker, for whom Decker Lake is named, was the construction foreman of the Collins' Overland Telegraph in 1865 and 1866, during construction of the line from Yale to a few miles north of Hazelton where construction was halted due to the success of the Atlantic Cable. He was born at LaGrange, Penobscot, Maine on 24 Aug 1827 and died on 8 May 1911 at age 83 at the Vancouver General Hospital, having lived at Belcarra on the north shore of Burrard Inlet since 1867. He was buried a pauper in a known grave at Mountain View Cemetery in Vancouver. There is no headstone to mark his grave." (November 2011 advice from researcher K. Guenter, Smithers.)
