A water supply gap analysis was conducted for each of
the eight river basins as described in Chapter 6. This
analysis concluded that the planned water supply
projects (the "Identified Projects and Processes") that
have been formulated by water providers and users
across the state, if completely successful, will provide
about 80 percent of the projected M&I water needs by
2030. There is also uncertainty associated with these
numbers. Significant M&I gaps were identified in the
following basins:
^ Arkansas Basin
^ Dolores/San Juan/San Miguel Basin
^ Gunnison Basin
^ South Platte Basin
Gaps between water demand or need and available
supplies are also anticipated for other types of water use
in virtually all basins, and the gaps in each basin could
be significantly larger if the Identified Projects and
Processes are not successfully and fully implemented.
As such, Section 8 describes families of future water
supply options based on: (1) projects and other solutions
identified through the Basin Roundtable discussions;
(2) projects and other solutions identified from existing
reports and studies; and (3) concepts identified by the
SWSI team.
To explore the merits of these potential water supply
options, an evaluation framework was needed. The
purpose of the evaluation framework was to ensure that
projects could be analyzed in a consistent, transparent,
and understandable manner. SWSI has identified and
considered a broad range of options.
Families of options were described in Section 8 and are
evaluated in this section. Section 10 describes specific
options that could be used in developing portfolios of
options. Any remaining gap not addressed by the
Identified Projects and Processes could be addressed
via these options.
Subsequent SWSI work can build on this information and ;~~'~~"~"'~'

This section presents the following:
^ An overview of the stakeholder process
^ An overview of the method used in evaluating ways to
address each basin's future water needs, or
evaluation framework
^ The specific water management objectives, sub-
objectives, and associated performance measures
^ The method and results used to gauge individual
Basin Roundtable members' preferences - the
importance each member placed on each objective
and sub-objective
^ The evaluation method that was employed to
evaluate the families of options and the results
9.1 Stakeholder Process
SWSI was designed to emphasize local input at the
basin/local level, reaching out to municipal water
providers, agricultural interests, business interests,
governmental agencies, environmental interests,
recreation interests, and the public at large. These
different interests represent the major stakeholders for
water use in Colorado. In total, over 40 Basin Roundtable
Technical Meetings and Public Information Meetings
were held throughout the state to solicit and exchange
information and ideas.
The SWSI stakeholder process was made up of three
elements (Figure 9-1):
^ Colorado Water Conservation Board
^ Basin Roundtables
^ Public Outreach
