Water Resources of the Woody Mountain Well Field Area, Coconino County, Arizona

Abstract

Conclusions drawn from a water resources study of the woody mountain area are: the average coefficients of transmissibility and of storage of the principal aquifer are approximately 30,000 gpd/ft and 0.05 respectively; drawdown in wells is greater than predicted using theoretical calculations due to the turbulent flow near the well bore in the fractured Coconino aquifer; the computed interference between pumped wells in the field ranges from 10.5 ft. To 19.7 ft. Interference would be negligible between wells spaced at distances greater than 6,000 ft. For pumping periods as long as two hundred days; the negative boundary effect of off-set on the oak creek fault may be balanced by the recharge effect of groundwater located in the highly permeable fractured zone adjacent to the fault; and the quantity of recharge water to the well field is greater than withdrawals from the wells.
