WATER AVAILABILITY

Method:

The Deer Beaver Creek hydrograph was derived as per USGS WRI Report 85-4086. See
hydrograph below. The summer and winter instream flow recommendations were reduced to 1.0
cfs (9/1-10/14), 0.4 (10/15-3131) and 0.75 (4/1 - 4130) based on the water availability analysis.
As per the Division 4 Engineer, senior water rights do not present a water availability problem
within this reach of stream.
