<br />Tables 2 and 3 show that the winter recommendation of 5.0 cfs (October 15th - April14'h) is
<br />available at least 95% of the time throughout the entire reach, Tables 2 and 3 also show that the
<br />summer flow recommendation of9,5 cfs (April 15th - October 14th) is available 50% of the time
<br />in April, August, September and October and 80% of the time May through July through out the
<br />entire reach,

<br />Precioitation Data
<br />
<br />Staff reviewed local precipitation data sets from 4 different sites located around the Fourmile
<br />Creek Drainage (see Precipitation Data in Appendix C), These sites include Guffy (1951-1997),
<br />Canon City (1931-1997), Lake George (1948-97) and Ruxton Park, (1959-1997) (See Figure 3),
<br />Table 4 shows the water year and the percent of average precipitation recorded at each site,
<br />
<br />Table 4: Precioitation Data as a oercenta e of Average,
<br />Water Year GuffY Canon City Lake Georl!e Ruxton Park
<br />1992-93 86% 94% 70% 88%
<br />1993-94 148% No Data 100% 129%
<br />1994-95 139% No Data 114% 133%
<br />1995-96 108% 115% 74% 95%
<br />1996-97 103% 165% 74% 169%
<br />
<br />Table 4 shows the wide variation of precipitation between four relatively close precipitation
<br />sites, the 1992-93 water-year was below average at all four sites, the 1994-95 water-year was
<br />above average for three sites and the 1995-96 water-year was above average for two sites and
<br />below average for two sites, It is staffs opinion that the five years of stream-flow data analyzed
<br />is representative of average to slightly above average water-years, However, because the
<br />requested flow amounts were exceeded at least 80% of the time, no adjustment to the
<br />recommended instream flow amounts was made, Figure 4 below shows the Fourmile Creek
<br />stream flow for the 1992-1997 time period.
