<br />Tables 2 and 3 show that the winter recommendation of 4,1 cfs (October 15th - April 14th) is
<br />available at least 80% of the time throughout the entire reach, except for the month of February
<br />where it is only available 50% of the time, Tables 2 and 3 also show that the summer flow
<br />recommendation of 8,2 cfs (April 15th - October 14th) is available at least 80% of the time
<br />throughout the entire reach,
<br />
<br />Precipitation 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 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,
