c.

One 900 KW Hydroelectric Power Plant measuring 30 feet long, 26 feet wide and 15
feet high (above ground level) containing two 450 KW vertical turbo.generators.

d.

A tailrace 300 feet long emptying into a pond in Viestanz-Smith Park. Tailrace will
consist of 48.inch reinforced buried concrete pipe,

e.

1055 feet of 24,000 volt, 3 phase 60 Hertz primary electrical transmission line
running easterlv from the hydroelectric plant to an existing transformer bank.

f. The total annual power production from this plant will be approximately 6,500,000
KWH,

The spillway section of the dam will be a concrete gravitv structure (Ogee section)
approximatelv 110 feet long and 24 feet high at the center. It will serve as a diversion dam
for the purposes of diverting up to 74 cubic feet per second of water to the hydroelectric
plant 1.6 miles downstream, The elevation of the spillway will be established at 6,017 feet.
The construction of the dam will result in a reservoir containing approximately 45 acre feet
of water. In addition the maximum "Flood of Record," (30,500 CFS) will discharge over
the spillway without damage to the dam or private property (Appendix A). The Colorado
Division of Highways plans to raise the elevation of U.S. Highway No. 34 at the dam site
from its present elevation sufficient to maintain adequate freeboard above the hundred year
flood level.

The destroyed aqueduct to be replaced consists of 300 lineal feet of 36 inch concrete pipe
and approximately 1,400 lineal feet of 36 inch treated steel pipe running along the river
bank just east of the dam.

The 1,700 feet of pipeline replacement will, by necessity, be installed along the river bank in
the same location as that which was destroyed. Excavation and direct burial of this section
of pipeline is not feasible due to the extremely rock nature of the path which the pipeline
must take.

Therefore, it will be necessary to place the pipe on compacted select fill material placing
the till on a 1 Yz:1 slope. The slope will be riprapped with natural stone. When completed the
pipe will not be visible and the riprapped embankment will take on a natural, aesthetically
pleasing appearance, blending the pipeline with the canyon walls.

The old hydroelectric power plant consisted of a building 30 teet wide, 60 teet long, and 18

teet high, housing three 400 hp horizontal hydroelectric generators rated at approximately

300 KW each. The building and generators were totally destroyed and no portion is

reusable.
