WATER AVAILABILITY

Method:

The Fouimile Creek hydro graph was derived using data from the steam gage on Fourmile Creek
below Cripple Creek (ill #07096250). See hydrograph below. The summer instream flow
reco=endation was reduced to 7.5 cfs (5/1-7/31) based on the water availability analysis. As
per the Division 2 E~ineer, senior water rights do not present a water availability problem
within this reach of stream.
