[Scorecard] how are we doing?

[Bob Zlomke]

Hi everybody,
 
It sounds like Rainer has the right idea about how to calculate the
proportion of water used that comes from the watershed.  
 
On the proportion of rainfall that is used by people, I don't remember
the numbers from Lisa that Rainer refers to, but for the precip
indicators for both watersheds we estimated the total annual volume of
rainfall, which can easily be compared with Peter's annual totals for
water use.  As to where we would address this issue on the Scorecard:
putting it under Recent Conditions would be illogical, because we
decided to make that Index reflect the hydrologic background,
independent of human management.  
 
Both Caitlin's questions come up, to my mind, under Stewardship:  the
first one under Water Use, where it would be natural to compare the
water use data that are being looked at directly with the precip data
from above (the Recent Conditions Index);  and the second one under
Water Self-sufficiency, where we have introduced the import totals.  I
suggest that Peter & Rainer consider incorporating those questions in
their respective sections.  If for some reason they don't seem to fit
very well there, maybe we shouuld put them under the Summary and
Recommendations (also by Peter).

Hi, all - 

Those two questions are key, and I think we can answer them.  The Water
Self-Reliance indicator, when teased apart (right now, it has two
"metrics" in it - even though they really are "indicators" in and of
themselves), shows what proportion of the water that's used by people
comes from the watershed.

The numbers Lisa put together in terms of AFAs coming down from the sky,
ending up in groundwater, estimated for evapotranspiration, and showing
up as flow might easily be put together with Peter's water use data.

	Peter and I were just talking, and we found that we were both
not sure that our evolving scorecard will convey an answer to the
question of how well the watershed is doing in providing water for human
and ecosystem uses. Are the indexes arranged properly to convey that
answer? What do you think?
	
	Here are a couple of very basic info-bits that our scorecard
could convey:

	*	What proportion of the water that falls on the watershed
is used by people (vs runoff, ET, gwtr recharge)? Reported as a pie
chart, including slices for major land use categories. Info for Sonoma
is in gwtr mgt plan. 
	*	What proportion of the water that's used by people comes
from the watershed? Reported as a percentage. 

	
	Where in the scorecard do these facts belong?
	
	Do we have a way to track volatility in weather? That is, not
dryness or wetness as we've discussed conveying in a row above our
indexes on the scorecard, but an indicator of expected increases in
frequency of droughts, storms, and floods.
	
	Any thoughts? 
	Caitlin
