Strategy for Consumptive Needs Assessment

This document summarizes an overall approach for developing consumptive use needs assessments, The strategy builds
on the Statewide Water Supply Initiative (SWSI) Phases 1 and 2, and policy initiatives from State leaders, The strategy also
addresses the incorporation of issues of common technical platform that are important for each Basin Roundtable in
developing their Needs Assessments, While the HB 1177 statute directs that the roundtables do these Needs Assessments,
the Colorado Water Conservation Board (CWCB) and the Interbasin Compact Committee (lBCC) will ensure that a
consistent technical approach is applied

This process will be kicked off in a workshop on August 1, 2007 in Denver. The Consumptive Workgroup membership was
formed based on the existing membership of the SWSI Phase 2 Gap Technical Roundtable (TRT) and from the Basin
Roundtables (BRTs)

Goal

The goal of this Group is to ensure a common technical platform is used when developing Consumptive Use Needs
Assessments and to help identify water supply alternatives on a statewide basis, Specific issues are outlined below.

Roles of Basin Roundtables and Consumptive Needs Assessment Group

To address common technical platform and to maintain consistency between roundtables when completing their needs
assessments, two statewide workgroups will be formed - a nonconsumptive workgroup and a consumptive workgroup, In
addition, the CWCB will be doing a Supply Availability Study, These three technical elements will serve to support the Basin
Needs Assessments as depicted in the figure
