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.
