Methodology Overview
Prioritization
Build Upon Attributes: The first step the Basin
Roundtables are taking in completing their
nonconsumptive needs assessments is building upon
the GIS information that was gathered during the
Statewide Water Supply Initiative Phase 2 (SWSI
Phase 2). The Basin Roundtables are suggesting
additional data that are specific to their basins be
added to the SWSI Phase 2 GIS database.
Establishing Priorities: The attributes gathered by
the roundtables will become the basis for
establishing priorities for the basins. Establishing
priorities will rely upon local input and knowledge.
The technical assistance team is providing GIS tools
to the Basin Roundtables as an initial starting point
for their priority setting.
Quantification
After priorities are set for their basins, the
roundtables will have to determine if and where
they would like to utilize quantification
methodologies. The technical assistance team can
assist the roundtables in developing site-specific
and watershed level quantification information.
Both of these methods will be piloted within the
next several months to provide further information
to the roundtables.
Schedule
The schedule for completing the majority of the
products for the nonconsumptive needs
assessments is shown in Figure 3 below. It is
anticipated that the Basin Roundtables will have
established priorities by June 2008. During the
remainder of 2008, the roundtables will be
reviewing information generated from the
quantification pilot studies and applying these
quantification strategies in their basins. Work on
site-specific quantification and the flow evaluation
tool will occur through 2009.
IVonconsumptive Needs Assessment
Products
Following are the anticipated products of the Basin
Roundtable Nonconsumptive Needs Assessments:
• A complete set of GIS coverages that represent
Colorado's important environmental and
recreational attributes.
• A map of prioritized areas and reaches, as
determined by the individual BRTs.
Generalized or "coarse" flow evaluation tools and
site-specific instream flow quantification
methodologies that will help BRTs understand
areas that might require more site-specific
investigation.
