The other activity which might be classi-
fied'more as office than field is in the San
Luis Valley where we have completed our pre-
liminary model of the San Luis Valley and
the significance of this is that we are able
to make our first tests of what the effects
of the salvage project would be on lowering
water level a in the area. What we have done
is taken the worst assumption, the worst
conditions, and made an evaluation of what
the water level lowering would be. It has
not been particularly great there but we
feel that we need to go to the more refined
assumption to demonstrate that the effects
will be less than those shown by the first
test on the model.

The other emphasis that we have been
putting on with regards to our office work
is to accelerate the development of an auto-
matic data processing system for handling
our data. The things that we tackled most
recently are to get ground water levels and
ground water withdrawals on punch card tapes
and on punch cards, I should say, so that we
can shorten the time between collection of
the data and dissemination of the data. The
other advantage is that we can put it out in
a variety of formats whereas before to accom-
plish this sort of thing was very laborious.

We are entering into a new phase of our
water management studies. I indicated at
the last meeting that the development of
this particular technique by Mr. Jenkins
permitted generalizing data to be handled
more easily in estimating what the effects
on the stream would be from pumping wells.
This permits us then to get into the third
phase of a four-phase study. The four phases
are indicated here in our handout.

The first phase was the effects on
groundwater storage caused by recharge and
pumping. This was accomplished through the
construction of an analog model. The second
