Section 9
Evaluation Framework
Table 9-1 SWSI Water
ctrves/5uq-~bfectives
1. Sustainably Meet Municipal & Industrial
^ Meet M&I demands during drought
^ Meet agricultural demands when and
where needed
3. Optimize Existing and Future Wate
^ Minimize non-beneficial consumption
(e.g., evaporation, phreatophytes)
^ Maximize successive uses of non-tributary
groundwater and other legally reusable
water
^ Maximize use of existing and new in-basin
supplies
4. Enhance Recreational Opportunitie
^ Provide adequate water for recreation
when and where needed
^ Encourage the cooperative multiple use of
water to enhance recreational and wildlife
opportunities
^ Provide adequate water for environment
when and where needed
^ Avoid/mitigate environmental impacts of
new projects
^ Protect and improve water quality
Pertormance Measures
On a scale of 1 to 5: 1 does not have the abiliiy
to reliably provide additional supply during
1950s drought; and 5 has the most abiliiy to
reliably provide additional supply during 1950s
drought.
Amount of additional supply provided during
1950s drought on a basinwide level as
aggregated from County demands; and
percent of major water providers that have
shortages during 1950s drought.
On a scale of 1 to 5: 1 does not have the abiliiy
to reliably provide additional supply during
1950s drought; and 5 has the most abiliiy to
reliably provide additional supply during 1950s
drought.
On scale of 1 to 5: 1 has high evaporation; and
5 has low evaporation.
On scale of 1 to 5: 1 impacts successive uses
of agriculture water; and 5 does not impact
successive uses of agriculture.
Not used for Reconnaissance Level screening
On scale of 1 to 5 for river based recreation
reaches, the number of months of river based
recreation will be the indicator: 1 is lower
months of river based recreation; and 5 is
higher months of river based recreation.
Not used for Reconnaissance Level screening
On scale of 1 to 5 using existing environmental
coverages: 1 reduces in-stream flows; 3
maintains current in-stream flows; and 5
increases in-stream flows.
Not used for Reconnaissance Level screening
On scale of 1 to 5: 1 degrades water quality; 3
maintains water qualiiy; and 5 improves water
qualiiy.
Amount of additional supply provided during
1950s drought on a basinwide level; and
amount of identified agriculture shortage
reduced by alternative.
Qualitative score based on reservoir surface
area and phreatophyte control water applied to
crops that is not being consumed.
Amount of additional municipal reuse (acre-
ff/year); and Qualitative score that is based on
projects that could impact successive uses
such as canal lining and higher efficiency
irrigation practices.
Percent of existing in-basin water supplies and
water rights that are fully used plus the percent
of existing trans-basin rights that are fully
reused.
Qualitative score based on estimate of
sustained high flows in commercial rafting
reaches.
Qualitative score based on guarantee of
minimum pool or stream flows during 1950's
drought.
Qualitative score based on measurement of
instream flows in current environmental
coverages which contain habitat areas
consisting of gold metal trout areas and
cold/warm water fisheries.
Qualitative score that examine flows in relation
to allowed depletions for areas within
Programmatic Biological Opinions.
A qualitative evaluation of water quality and
flow on a basinwide basis.
