Figure 3.--Average daily streamflow at station 07105800 Fountain
Creek at Security, 1981 water year.

Fountain Creek and the Fountain Creek alluvium are important sources of
water for use within and outside the study area. Approximately 23 streamflow
diversions are located along Fountain Creek in the ~tudy area. The locations
of these diversions are shown in figure 5; the quantities of the diversions
are listed in table 1. Most diversions are for irrigation of crops in the
valley, but some diverted streamflow (by ditches 01, 03, and D9, table 1) is
used to artificially recharge the alluvium. According-to records available
from the office of the Division Engineer, Colorado Division of Water Resources,
Pueblo, (Thomas C. Simpson and Robert L. Ermel, written commun., 1985), annual
diversions of streamflow from Fountain Creek within the study are1r"averaged
about 47,600 acre-ft during the 1980 through 1984 water years. In addition,
as of 1984, approximately 240 wells completed in the area had reported yields
greater than 100 gal/min (Cain and Edelmann, 1986, p. 6). Withdrawal of
ground water in the are~ probably is about-. 15 ;000 to 20,000 acre-ft!yr (Cain
and Edelmann, 1986, p. 8); however, because of recharge by Fountain Creek, no
long-term changes in water levels have been reported (Bingham and Klein,
1973, p. 5). Use of ground water is divided nearly equally between municipal
and agricultural use.
