WATER AVAILABILITY

Method:

The North Texas Creek hydrograph was derived as per a % of Gage # 09107500: Texas Creek at
Taylor Park. See hydrograph below. The winter instream flow recommendation was reduced to
0.75 cfs (10/1-12114) and 0.5 cfs (12115-4/30) 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.
