Historical Note
Seattle City Light provides electricity and electrical and conservation
services to its public and private customers. It is the largest public utility
in the Pacific Northwest. Public responsibility for electrical energy dates to
1890 with creation of the Department of Lighting and Water Works. In 1902,
Seattle voters passed a bond issue to develop hydroelectric power on the Cedar
River under the administration of the Water Department. Electricity from this
development began to serve Seattle in 1905. A City Charter amendment in 1910
created the Lighting Department. Under the leadership of Superintendent James
D. Ross, the department developed the Skagit River hydroelectric project, which
began supplying power in 1924. Both public and private power were supplied to
Seattle until 1951 when the City purchased the private electrical power supply
operations, making the Lighting Department the sole supplier. The Boundary
Project in northern Washington began operation in 1967 and currently supplies
over half of City Light's power generation. Approximately ten percent of City
Light's income comes from the sale of surplus energy to customers in the
Northwest and Southwest. The current name of the agency was adopted in 1978
when the Department was reorganized.
Historical Background
The original Gorge Dam was the third dam built by Seattle City Light on
the Skagit River. Construction of the dam involved building a railroad to
transport materials from Rockport to the dam site. The railroad was completed
between 1920 and 1922. The dam, finished in 1924, included a diverting weir
near the mouth of Gorge Creek, an 11,000-foot tunnel through solid granite, a
power house, and a transmission line.
Photographs in this series document a later project at Gorge Dam which
began in 1948 and included a powerhouse and a diversion dam. The Gorge Plant
Powerhouse was completed in 1951, and construction of the Diversion Dam began
in February 1955. The Gorge Diversion Dam was built 2 ½ miles above Gorge
Powerhouse. The Gorge Diversion Dam was designed to make more efficient use of
the Skagit River water flowing down from Diablo Dam, about five miles up the
river. It replaced the wood crib dam which had been diverting the river water
into the Gorge Powerhouse tunnel since 1924. Gorge High Dam was dedicated in
1961 and completed in 1962.

Gorge Diversion Dam, 1948-1950
Prints of the Gorge Diversion Dam date from 1948 to 1950 and are
composed of two series. The “G” negative numbers document early work on Gorge
Diversion Dam, from November 1948 to April 1949. These images document work
done by Cascade-Phillips Company. The images are 5 ½ x 7 inches and are mounted
in a photograph album with descriptions, dates, and negative numbers.
The second series are “GDD” negatives and document the project
from 1949 to 1950. Some prints from both series (primarily the GDD series), as
well as a narrative history of the Gorge Diversion Dam project compiled from
Project Engineer diaries, make up the unpublished volume “Gorge Diversion Dam:
Record of Construction” which is included in this series. Also included in the
album are “GT” series prints.
