7.0 HYDROELECTRIC FACILITIES

The hydroelectric facility design is described in this
chapter, and includes the equipment selected for inclusion in the
feasibili ty study. The equipment was selected to allow for cost
estimate to be made and to assure that it is available. However,
the actual equipment installed may be different. The design
calculations are summarized in this chapter and the backup data is
described in the appropriate appendix.

The hydroelectric power plant would be installed in the gate
chamber of Lemon Dam and would utilize the existing bypass pipe
through the chamber as a penstock. This chapter describes the
existing facilities, installation and selection of the turbine,
head and flow, electrical equipment, and cost estimates.

7.1 EXISTING FACILITIES
The Lemon Dam spillway and outlet works are located on the
right hand side (looking downstream) of the embankment. The
spillway is un gated with the outlet at elevation 8148 feet. The
intake structure for the outlet works is also located on the right
hand side of the dam and has an inlet elevation of 8005 feet. The
top of the structure is at elevation 8018 ft. Water enters a
five-foot diameter vertical pipe through the intake structure; the
5-ft pipe makes a 90 degree vertical to horizontal bend then
expands to a 8. 5-ft diameter pipe which conveys water 900 ft to
the gate chamber/outlet control gates.

Releases through the outlet works are controlled by two pairs
of outlet gates, each capable of releasing 455 cfs at maximum
water surface. Below the gates is a nine-foot high horseshoe
shaped, unpressurized tunnel which daylights to the river channel
below the dam. The outlet gates are operated in the gate chamber
which is on the center line of the dam.
