loeated On Coal Creek, a tributary of Sand
Creek, near Aurora, Colorado, just east of
Buckley Field. The project would control
the runoff from the drainage of 83 square
miles of the Sand Creek basin and would
provide storage of 5,000 acre-feet for
sediment and 20,800 acre-feet for flood
control. The dam would be of compacted I~
earth and would be about 10,000 feet long
and 100 feet high. The outlet works would
consist of a concrete intake structure with
a low-level intake, a concrete conduit, and
a stilling basin at the downstream end of
the conduit. An earthcut spillway would
be located in the left abutment of the
dam. The full-pool surface area of the
reservoir would be 1,730 acres. Although
there would be no permanent pool for
recreation, facilities for general land-
based recreation would be developed in the
area. Approximately 570 acres of land in
the flood plain downstream from the Sand
Creek Dam would be required for reservoir
releases, or flood control, and for open
space development. The estimated total
cost of the project is $19,026,000.

The Toll Gate Creek Dam and Reservoir
would be located near Aurora, Colorado~ at
the junction of East and West Toll Gate
Creeks. The reservoir, with storage for
the probable maximum flood, would control
the entire 32-square mile drainage area
of the two sub-basins. The reservoir
would include 2,000 acre-feet of storage
for sediment and 8,300 acre-feet of stor-
age for flood control. The full-poOl
surface area of the reservoir would be
1,250 acres. The compacted earth dam
would be about 10,500 feet long and 85
feet high. Outlet works would be provided ~
to regulate reservoir discharges. The out-
let works would consist of a concrete
intake structure with a low-level intake,
a eonerete eondait, and a atilling ba.in II
