2.4,2,2 Spillway Design - The asslrned design capacity of the spillway
Is the same for all the dam alternatives or 65,300 cfs (1849 m3/s),
The crest length and the amount of concrete In the spillway would be
the same as Alternative A except the height of the Reinforced Earth(r)
walls would be 8-feet (2.4 m) less than for Alternative A.

2.4.2.3 Outlet Works - The arrangement of the outlet works would be
the same as Alternative A except 40-feet (12.2 m) shorter. Because of
the reduction of head, the capacity at the high water 1 ine would be
951 cfs (27 m3/s).

2.4,2.4 Material Sources - Roughly 213,000 cubic yards (162,850 m3)
of material would be required to build the dam. The proposed sources
of materials would remain unchanged from Alternatives A and B.
Slightly less material from the Riprap Source area and from Borrow
Area E would be required for the construction of Alternative C than
for Alternative A or B. Again fill within the White River may be
required to complete access roads to the borrow areas,

2.4.3 Reservoir Operation

2.4.3.1 The only difference in reservoir operation between

Alternatives A and C would be the operating relationship between

outlet works and spillway. The Intent would be to have the outlet

works operate to pass the entire flow of the river during the winter

time to eliminate the problem of ice jams that occur In Rangely.

Proportionally less water would be available for sale due to the

smaller reservoir volume.
