Reservoirs could also provide for retention
of the basin's flood runoff for possible
groundwater recharge within the basin.

During our studies, we investigated the
feasibility of constructing small dams in
the upstream areas of the Bijou Creek basin.
We found that a system of small reservoirs
on minor tributaries would not provide a
significant reduction in floodflows along
the main streams of the Bijou Creek basin.
A study by the Soil conservation Service for
the East Bijou Creek basin also found that a
system of small dams and reservoirs would be
economically infeasible.

A system of nine larger reservoirs was
investigated. Their sites were selected to
provide optimum control of the basin's run-
off. Detailed engineering and economic
studies indicated that only four of the nine
reservoirs would be economically feasible.

This display map shows the system of
four reservoirs which we are presenting for
your consideration. Two reservoirs would be
located on East Bijou Creek, one on Muddy
Creek, and one on West Bijou Creek.

The four-dam system would control most
of the runoff from a recurrence of the 1965
flood and would substantially reduce flood
damages in the Bijou Creek basin downstream
from the dams. In combination with the Bureau
of Reclamation's proposed Narrows reservoir
on the South Platte River, the plan of im-
provement would also provide a significant
reduction in the flood damages along the
South Platte River between Bijou Creek and
North Platte, Nebraska. The four reservoirs
would provide storage of 251,900 acre-feet
for flood control and sediment. The sediment
storage zones of the reservoirs could provide
up to 49,400 acre-feet of storage for ground-
water recharge.
