Challenges

Dry years and regulatory actions have driven groundwater levels downgroundwater levels down

Deeper wells and more pumps Deeper wells and more pumps = higher costs

O 600 ll ho Over 600 new wells have been drilled in Kern County since 2007


What Lies Ahead, or below...

Need a Delta solution

o Long-term solution

o Groundwater banking is like a financial institution, if there isn’t any money (surface water) a bank is useless.

Need short-term measures to help us survive until we have a Delta solution

Stockton

Need to address concerns regarding local groundwater conditions Clifton Court Forebay
