 Introduction

The following information is a "work in progress".  As I find more information, it will be added to this page.  If you have any questions, please contact me at minortree@charter.net.

  • "The industrial demand for electricity is a primary cause of the great hydroelectric activity. . . " [b]

  • "The Pit River is remarkable for its natural regulation, this being brought about by the existence of the many springs and subterranean flows originating in underground reservoirs occurring in the porous areas of Fall River, Hat and Burney Creeks." [b]

  • "The full development in the basin from a point on Fall River above Fall River Mills to a point on the Pit below the 'Big Bend' ". [b]

  • "Possession by the company of Pit River and the starting of this project is due to the vision of Mr. Frank G. Baum, consulting hydroelectric engineer for the Pacific Gas and Electric company, and the work is going on under his immediate supervision." [b]

 

Pit 1 Diversion Dam

  • Located on the Fall River. [b]

  • Water is moved through 1,150 ft. of "open cut" and a 10,160 ft. tunnel through the mountain with a 14.3 ft. diameter penstock of 1400 ft. lead to the powerhouse. [b]

 

Pit 1 Powerhouse

  • Built by Pacific Gas & Electric Co.

  • Construction began in 1920, operation started Sept 30, 1922. [c]

  • Receives water from the Fall River [c] through a 2-mile long tunnel through a mountain and penstocks that drop 454 ft.

  • McCloud River Railroad built and operated a rail line to the building site to bring in materials.  The route was 23 miles from Bartle to Peck's Bridge (now under Lake Britton), then 10 miles up the Pit River. The railroad was dismantled in 1929.


Pit 2 Diversion Dam

  • Was never built.

 

Pit 3 Diversion Dam (Lake Britton)

 

Pit 3 Powerhouse

  • Started operations on July 18, 1925. [a][c] 

  • 1922 railroad used for Pit 1 extended from Cayton Valley to the site. [c]


 

Pit 4 Diversion Dam

  • Built in 1955. [c]

 

Pit 4 Powerhouse

  • Began operating during the fall of 1955. [a][c]

 

Pit 5 Diversion Dam

Pit 5 Powerhouse

  • Built during WWII and began operating April 29, 1944. [c]

James B. Black Powerhouse

  • Completed 1965. [c] 

  • Dedicated to the memory of James B Black, PG&E president for 20 years (also Shirley Temple Black's father-in-law). [c]

  • Uses McCloud River water from Iron Gate Reservoir through an 8-mile-long 17 ft. diameter tunnel and mile-long penstock. [c][f]

 

Pit 6 Diversion Dam and Powerhouse

  • Completed 1965. [c]


Pit 7 Diversion Dam and Powerhouse

  • PG&E purchased in 1945. [c]

  • Built in 1920[1]

  • Began operating in 1921 [a][b][c]

  • Uses mainly Rising River water. [b]

  • Built on Hat Creek in Cassel. [b]

  • 180 ft. long spillway, radial gates for water control.  [b]

  • 2750 ft. ditch connects the diversion dam and the small Hat #1 forebay.  [b]

  • 1700 ft. penstock delivers the water to Hat #1 Powerhouse.
     


 

Hat #1 Powerhouse at Crystal Lake/Baum Lake

  • Built by the Red River Lumber Co.and operated by PG&E. [c]  PG&E purchased in 1945. [c]

  • Water added to Hat Creek from Crystal Lake and Rock Creek [b] just below Hat #1 Powerplant [b], on Hat Creek, just above Hat Creek Falls.

  • Water moved thru a flume 4,469 ft to head of the penstock. [b]

  • Flume ends in another forebay with radial gates. [b]

  • Water is carried to the powerhouse through a 400 ft long penstock. [b]

Redding Waterwheel

  • In the mid 1880's, San Francisco businessman/investor Francis Smith, through his employee Samuel P. Fillman, installed a water system for Redding. In 1889 he directed the building of an "enormous water wheel. . . which ran a generator and furnished power" to Redding. Located at the south end of the North Market St Bridge. "put the gas lighting company out of business." [c][d]

  • Lights first turned on for a portion of the town on April 1, 1890. [d]

  • "The first electric power used in Redding was generated by a large paddle wheel located in the wheel ditch in the river near the foot of what is now Pine Street. This was built and operated by Samuel P. Fillman for the Francis Smith interests of San Francisco. He also installed the first water system, pumping water from the river near the wheel ditch. This was later replaced by a steam and turbine operated electric plant near the Free Bridge. The water was also pumped from here to a reservoir at top of the hill on Gold Street. The Smith interests in Redding were finally acquired by the Northern California Power Company, which brought in power from Volta near Shingletown and moved the pumping plant and substation to Jenny Creek northwest of Redding." [f]

Freebridge Substation at Redding

  • Stone building built about 1899 used as a substation to distribute power generated at Volta to Redding. [c] 


Fall River Hydro-Electric Generating Plant

  • Built by Mr. Zumwalt in 1890. "Located where the Fall River cascaded seventy-five feet down to join the Pit."  Operated until Pit 1 was built in 1921. [c]

Volta

  • 1899 construction begun by H.H. Nobles.  [c]

  • AKA Shannon Plant  [c]

  • Began operating Nov.  28, 1902. on South Battle Creek, [c]

  • Supplied power to Mountain Copper Company at Keswick.  [c]

  • Second stone building built 1906. [c]

  • Buildings described as  "lava rock laid in mortar". [e]

 

Snow Creek near Inwood

  • In the early 1900's Shasta Power Company constructed a small plant on Snow Creek in the vicinity of Inwood. . . camp for the operation was located at Sunflower Hill". [c]

 

Kilarc Forebay

  • "Kilarc Forebay was constructed in 1902 and is situated on a flat plateau at the west end of a spur from Miller Mountain above Whitmore. Created by the earth filled Kilarc Forebay Dam which is 13 feet high and 1,419 feet long. . . volume capacity of 30 acre feet." [g]
  • "Water is delivered to the forebay from an eight foot high diversion dam across Old Cow Creek via the 3.65 mile Main Canal constructed in 1903-04 that runs along the edge of the Old Cow Creek canyon."  Specifically, this canal consists of 2.03 miles of actual canal, much of it lined with concrete, 1.44 miles of flume and.18 miles of wood-lined tunnel."

Kilarc Powerhouse

  • Built by H.H. Nobels in 1904 on Old Cow Creek near Whitmore. [c]
