Snettisham Project Alaska. First Stage Development. Design Memorandum Number 7. General Design Memorandum. Volume I. Main Report.

Abstract

The Snettisham Project consists of a plan to construct a concrete gravity dam at the outlet of Long Lake (near the mouth of Speel River, 28 airmiles southeast of Juneau, Alaska) to raise the lake to elevation 895 and to drill a 8,175-foot power tunnel and a 1,710-foot penstock from Long Lake to a 40,600 KW powerplant at tidewater. Tunnel intake, trashrack and surge tank are included in the waterways construction. From the switchyard, adjacent to the powerplant, a 47.3-mile, 138,00-volt transmission line will extend to a substation near Juneau. Drill a 6,000-foot power tunnel and a 1,690-foot penstock tunnel from Crater Lake to the powerhouse. Increase the powerhouse capacity to 60,900 KW.
