James Delmage (J.D.) Ross is known as the Father of Seattle City Light. Ross helped design and build the power plant at Cedar Falls on the Cedar River. He also can be credited for the hydroelectric project on the Upper Skagit River, which provides 40 percent of Seattle’s electricity. Ross Lake and Ross Dam on the Skagit are named in his honor. Ross is fourth from the left in this photo.

The Gorge Dam and powerhouse was built first for a total cost of $13 million. In 1924, the generators began transmitting power 100 miles to Seattle, after President Calvin Coolidge  started them from the White House by pressing a golden key, reports HistoryLink.

Next, Ross began the Diablo Dam project. Private energy firms tried to take him down, labeling his idea of a publicly-owned utility as socialism in action. Ross was fired by the Seattle mayor, but Seattle voters disagreed. They had a special election and threw out the mayor for someone who would rehire Ross. Diablo Dam began producing electricity in 1936.

People were so excited to use and work for City Light that they had parties, joined teams and made parade floats. Here is an excerpt of a poem written by Carlton Fitchett in 1945 to glorify City Light: “He dreamed of dams and power plants that run the household gadget, and when the kid outgrew his pants they moved him to the Skagit. Where torrents swollen by the rain engaged in awesome frolics, he grabbed white horses by the mane and tamed them with hydraulics.”
