Upper Canal
The upper canal of the Beaver Park irrigation system
runs from the outlet of the aqueduct westward to Brush Hollow
Reservoir. The total length of the canal is 20,150 feet.
The total fall of the canal is 24 feet with an average grad-
ient of ,0012, The ditch was dug by men and horses and it
traverses considerable lengths of limestone outcrops, As a
result, the gradient of individual canal segments varies
widely, from ,000] up to .005, The average gradient of the
first 10,000 feet is .0008 and of the second 10,000 feet is
,0014.
Nine laterals withdraw water from the upper canal for
delivery to irrigation or directly to the lower canal for
distribution to other laterals, The present total capacity
of the laterals is about ]0 cfs, Figure 2 shows a profile
of the ditch and the location of the laterals and their numb-
ers. The distance stations on the canal are in hundreds of
feet from the parshall flume, The present conveyance capacity
of the upper canal is about 50 cfs when all of the laterals are
operating and water can flow into Brush Hollow Reservoir.
Cross-sections of the ditch at 1000-foot intervals are in-
cluded in the appendix.
The first 700 feet of. the ditch below the parshall flume
is contained in a concrete and rock masonry channel because
of the steep gradient through a rock outcrop, West of that
section, the canal is unlined and has an earthen or rock
bottom, depending upon the presence of rock outcrops. The
ditch width varies from 10 to 20 feet and flow depths range
up to about] feet. Maintenance of the channel section and
