<br />
<br />IV, Publish a report using data collected from the ground water recharge sites and extent of
<br />present ground water recharge to provide a better understanding of the dynamics of ground
<br />water recharge in the San Luis Valley. The value of perfonning an integrated water
<br />management plan for the San Luis Valley will also be analyzed,
<br />
<br />Investigate recharge alternatives that have the potential of increasing the use of the
<br />unconfined and confined aquifers as a storage reservoir,
