WATER AVAILABILITY

(Water Yr)
(1992-93)
(1992-97)

The Fourmile Creek hydro graph was derived using data from the steam gage on Fourmile Creek
below Cripple Creek (ill #07096250). See hydro graph below. The summer instream flow
recommendation was reduced to 7.5 cfs (7/1-7/31) based on the water availability analysis. As
per the Division 2 Engineer, senior water rights do not present a water availability problem
within this reach of stream.
