WATER AVAILABILITY

Method:

The Fourmile Creek hydrograph was derived using a percentage of the flow data from the stream
gage on Fourmile Creek below Cripple Creek (% ofID # 07096250). See hydrograph below.
The summer instream flow recommendation was reduced to 3.0 cfs (8/1-10/31) 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.
