<br />Metropolitan Water Supply Investigation <br /> <br />Executive Summary <br /> <br />THE BROADER BENEFITS OF THE COLLABORATIVE <br />MWSI PROCESS <br /> <br />The MWSI has been both a technical evaluation of cooperative water supply <br />opportunities and a continuing process of dialogue, mutual education, joint inquiry, and <br />collaboration among over 60 Front Range water providers and representatives of other <br />key stakeholders including environmental organizations, agriculture and the West Slope. <br />While this diverse group has focused principally on the opportunities and limitations <br />associated with the four cooperative water supply categories, participants also developed <br />and shared considerable information regarding the future water needs of the metro <br />Denver area and individual water providers' plans that are in place for meeting those <br />needs. <br /> <br />This information, summarized in the table and text below by sub-region, provides <br />valuable context that enhances understanding ofthe roles and benefits of the cooperative <br />water supply opportunities evaluated through the MWSI. <br /> <br /> Projected Reasonably <br /> Future Water Basis of Certain Future Future Unmet Applicable Cooperative Supply <br />Sub-reGion Demand AF Proiection Suoolv.

As described further below, the <br />cooperative water supply opportunities evaluated in the MWSI could supplement or <br />partially replace the plans individual water providers already have in place. <br /> <br />x <br /> <br />Prepared for the Colorado Water Conser....ation Board, Colorado Department of Natural Resources by <br />Hydrosphere Resource Consultants, 1002 Walnut Street, Suite 200, Boulder, CO 80302 <br />
