GENERAL

I.

1. PURPOSE AND SCOPE. The purpoae of thia design memorandum
is to present basic hydrologic data for use in developing the
project plan for the Fountain Creek Reservoir, Fountain Creek,
tributary of the Arkansas River in Colorado. Design Memorandum
No.2, Hydrology - Part II, will present storage allocations and
reservoir routings, or other data dependent on the project
plans. The project alternatives to be considered include a
multiple purpose reservoir, s single purpose reservoir, and
levees and channel improvement on Fountain Creek.

2. AUTHORIZATION AND LOCATION OF PROJECT. Congressional
authorization for the project is contained in H.D. 93-143,
September 5, 1973 and in the Water Resourcea Development Act of
1974, Public Law 93-251, HR 10203, March 7, 1974. The project
is located on Fountain Creek about 1.5 miles upstream from the
city limits of Pueblo, Colorado. A levee and channel improve-
ment alternative plan would be located on Fountain Creek and
extend through the city of Pueblo.

3. EXISTING FLOOD CONTROL IMPROVEMENTS. There are two
multipurpose reservoirs in the study area that have flood
control as a function. The largest of these is the Bureau of
Reclamation's Pueblo Reservoir which is located on the Arkansas
River 5 miles upstream from Pueblo. The reservoir, in accor-
dance with prescribed flood control regulations, will regulate
the standard project and smaller floods to nondamaging rates in
the Arkansas River floodway through the highly developed portion
of the city of Pueblo. The reservoir, however, is unable to
regulate the SPF to a nondamaging rate in the Arkanaas River in
the reach between the lower end of the floodway and the conflu-
ence with the St. Charles River. The Corps of Engineers'
Trinidad Reservoir provides SPF protection to Trinidad, Colo-
rado. It is located 6 miles upstream from Trinidad and has a
flood control storage of 51,000 acre-feet. In addition to these
two reservoirs, there are four significant channel improvements
in the study area that provide flood control. .These are the
Monument Creek Channel Improvement and Templeton Gap Floodwny in
Colorado Springs, and the Fountain Creek Channel Improvement and
the Pueblo Floodway on the Arkansas River in Pueblo. There are
