WATER AVAILABILITY

Method:

The Deer Creek hydrograph was derived as per the USGS WRI Report 85-4086 (Mountain
Region). See hydrograph below. The Summer & Winter instream flow recommendations wer
reduced to 1.0 cfs (4/15-7114),0.5 efs (7/15-8/14) and 0.3 efs (8/15-4/14) based on the water
availability analysis. As per the Division 1 Engineer, senior water rights do not present a water
availability problem within this reach of stream.
