site could serve. The proposed High Hells Canyon Dam would 

 have been a monumental, concrete arch structure, 1,733 feet long 

 at the crest and 722 feet in maximum height. This structure also 

 would have developed fully the 602 feet of fall in the Hells Canyon 

 Reach of the Snake, with 800,000 kilowatts of installed capacity 

 initially, and 100,000 to be added subsequently for an ultimate 

 total of 900,000 kilowatts at site. The 3.8 million acre-feet of 

 usable storage, as contemplated in the design for the High Dam, 

 would have warranted installation of 774,000 kilowatts of additional 

 generating capacity at downstream structures on the lower Snake 

 and Columbia rivers. The total of 1.6 million kilowatts was destined 

 for incorporation in the federal hydroelectric system and, upon 

 completion, would have represented about 16 per cent of the 

 system's total. 



Against this backdrop, the Idaho Power Company proposal 

 represents, from a financial standpoint, a substitution of private 

 financial resources for investment funds originating in public 

 financing — and the provision without compensation of certain
