the pipe line drops down the narrow valley eastward, 5-1/2 miles, to an
elevation of 6,980 ft, where it turns abruptly north, rising in 1 mile
to a table-land, 7,215 ft. above sea level, across which it continues
northward 5 miles to the storage reservoir, which is on the north edge
of this elevated country. Hereafter, this reservoir will be called the
Nogal Reservoir, from the old mining village of Nogal lying 1-1/2 miles
to the north and 600 ft. below it. From this reservoir, the line drops
abruptly to the Carrizozo plain, and crosses the latter northward to
Coyote, at Mile 156, on the railway, at an elevation of 5,810 ft.,
passing, on the way, 6 miles east of Carrizozo, to which a branch pipe
runs, Carrizozo being 5,430 ft. above sea level. There is a
2,500,000-gal. reservoir at Coyote, and a similar one at Carrizozo.

This describes the gravity section of the line which brings the water
from the mountain stream to the railway. From Nogal Reservoir to the
latter, the capacity of the pipe is equal to the future daily
requirements; from the source of supply to the reservoir, the pipe has
twice as great a capacity, thereby storing surplus water. This section
is 32 miles long, with a 6-mile branch line.

The second, or pumping section, extends eastward along the railway,
rising from an elevation of 5,810 ft. at Coyote to 6,750 ft. on the Corona
summit, which is the water-shed line between the Rio Grande on the west
and the Rio Pecos on the east. At Coyote a pumping station lifts the
water to Luna Reservoir and the pumps at Mile 171, and the latter lift
it to the reservoir on Corona summit at Mile 192-1/2. This section is
