r , The principal spillway would be located in the ri/(ht or southern abut- ment. The principal spillway (as well as the reservoir) was designed to accommodate an inflow design flood with a peak flow of 485,000 ds and a la-day flood volume of 1,918,000 ac-ft. A primary outlet structure consisting of a 14 ft diameter pipe would be located between the principal spillway and the present stream channel. Just south of the primary outlet structure, an irrigation outlet structure consisting of a 9 ft diameter pipe would be provided to deliver water to the Bijou Canal. In the left abutment, an irrigation outlet structure consisting of a 10 ft diameter pipe followed by a 4.5 mile canal to deliver water to the Riverside Canal.
