side of the ditch, The difference in vegetation is notice-
able while walking along the ditch, but is strikingly
noticeable on aerial photographs taken during the growing
season. Large areas of loss can be observed where the upper
canal crosses Highway 115 and on the lower canal between
Brush Hollow Dam and Third Street,
Because the Beaver Park system operates on a year-
round basis, either for irrigation or storage or domestic
use, there is a constant year-round loss of the water which
is measured into the ditch system, The rate of loss varies
with the amount of water in the ditch but the percentage of
ditch loss is probably on the order of 30% of the water
diverted, This does not include the lateral losses which
might be another 20%,
The monthly diversions of the Beave~ Park system for
the 1963-1978 period are shown on Table 3. The average
annual diversion of 12,345 acre feet per year would appear
to be sufficient water for the irrigation of 3400 acres un-
til one considers the amount of ditch and lateral losses in
the system. 72% of the diversions (8904 AF) occur during the
growing season, the remainder is diverted primarily for do-
mestic use and storage in Brush Hollow Reservoir.
Table 4 presents the monthly contents of Brush Hollow
Reservoir for the period 1968-1978, The capacity of Brush
Hollow is about 4100 acre feet and its primary purpose is to
store water in winter months to release for irrigation use in
times of low available diversions from Beaver Creek. In add-
ition, Beaver Park Water has a fifteen-year lease with the
Colorado Division of Wildlife for use of the reservoir and
surrounding lands for recreation, The lease provides that.
Beaver Park will maintain the reservoir level at a gage
height of over 25 feet if possible, This level will provide
a storage content of 632 acre feet,
The Division of Wildlife has stocked Brush Hollow
Reservoir for many years with bass, catfish, walleye pike,
and some trout, The reservoir provides a good fishing area
for the Fremont and El Paso County areas, The 1978 fishing
