I I4 <br />~~~~~~~~~~_. <br />1~:~4~[_11~:L:L:S <br />Methodology Overview <br />Prioritization <br />Build Upon Attributes: The first step the Basin <br />Roundtables are taking in completing their <br />nonconsumptive needs assessments is building upon <br />the GIS information that was gathered during the <br />Statewide Water Supply Initiative Phase 2(SWSI <br />Phase 2). The Basin Roundtables are suggesting <br />additional data that are specific to their basins be <br />added to the SWSI Phase 2 GIS database. <br />Establishing Priorities: The attributes gathered by <br />the roundtables will become the basis for <br />establishing priorities for the basins. Establishing <br />priorities will rely upon local input and knowledge. <br />The technical assistance team is providing GIS tools <br />to the Basin Roundtables as an initial starting point <br />for their priority setting. <br />Quantification <br />After priorities are set for their basins, the <br />roundtables will have to determine if and where <br />they would like to utilize quantification <br />methodologies. The technical assistance team can <br />assist the roundtables in developing site-specific <br />and watershed level quantification information. <br />Both of these methods will be piloted within the <br />next several months to provide further information <br />to the roundtables. <br />Schedule <br />The schedule for completing the majority of the <br />products for the nonconsumptive needs <br />assessments is shown in Figure 3 below. It is <br />anticipated that the Basin Roundtables will have <br />established priorities by June 2008. During the <br />remainder of 2008, the roundtables will be <br />reviewing information generated from the <br />quantification pilot studies and applying these <br />quantification strategies in their basins. Work on <br />site-specific quantification and the flow evaluation <br />tool will occur through 2009. <br />IVonconsumptive IVeeds Assessment <br />Products <br />Following are the anticipated products of the Basin <br />Roundtable Nonconsumptive Needs Assessments: <br />• A complete set of GIS coverages that represent <br />Colorado's important environmental and <br />recreational attributes. <br />• A map of prioritized areas and reaches, as <br />determined by the individual BRTs. <br />Generalized or "coarse" flow evaluation tools and <br />site-specific instream flow quantification <br />methodologies that will help BRTs understand <br />areas that might require more site-specific <br />investigation. <br /> cuu~ cuu~ <br />TAS K z°° ~ a~ <br />Q w a a a <br />~ <br />~ z ~~ a~> v <br />>>> w v o w <br />~ <br />cn <br />o <br />o Q w a a a>> <br /> <br />~ <br />~ <br />~~~a~ <br />~ <br />~~ <br />-~ - ~~ <br />~a~ <br />~ <br />~z~ <br />------ ~~~ <br />~~ <br />~~~a~ <br /> <br />Priorities - <br />Build Upon Attributes '~, <br />Establish Priorities ~~ ~ ; ~~ ~' <br />Quantification <br />Where to Quantify? ~ ~ <br />Site-Specific Quantification ~' <br />Flow Evaluation Tool ~ ~ ~ <br />Implementation ~ - - - - ~ --~ - -- - - <br /> Fi~ure 3 <br /> Schedu/e <br /> -4- <br />
