for the water mitigation plan. A slight deficit will exist
for dry years like 1954 and a slight credit will exist for
wet years like 1969. The 4 . 45 shares supported the irrigation
' water portion of the consumptive use of 18. 3 acres of pasture.
' Figure C-12 illustrates the monthly comparison of the existing
and future net depletions for normal years for the water
' mitigation Plan. In the months of November through February,
' there will be more depletion (a deficit) for the future
condition, and less depletion (a credit) for the months of
' March through October. On an annual basis there is a balance,
indicating no net impact.

tGround Water. Dry mining operations will lower water levels
in the immediate vicinity of the excavated area. Based on
' an analysis of the alluvial deposits, it is estimated that
the maximum radius of influence from dewatering will be 300
feet. Beyond this distance there will be no appreciable
i-
' effect on the ambient water table from gravel excavation.
' Mining operations will be maintained at distances more than
300 feet from existing wells and South Boulder Creek to
avoid adverse effects.' There are no irrigation wells in the
' vicinity of the project and the few domestic wells that are
near the site are up-gradient and far enough from excavated
areas to be beyond the zone of influence.
