The Fourmile Creek hydrograph was derived using data from the steam gage on Fourmile Creek
below Cripple Creek (ID #07096250). See hydrograph 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_
