quite dramatic here, still is not extremely
serious to a number of people. We are
talking about a decline of about l~ feet
per year. But you can imagine now when you
compare this with what is happening in the
Texas High Plains where they are getting
declines in excess of five feet and in some
areas as much as ten or fifteen feet per
year.

We are talking now about a law that
tells us what we want to do to conserve our
supply of water so that at the end of 25
years we still have 60 percent of our water
left. Here we show what is happening and
how dramatic it can be, particularly for some
wells. This illustration shows that at the
end of 25 years average depletion in the
area is 40 percent of the original volume.
However, the effect on individual wells varies
appreciably. For example, well I has been
depleted by 60 percent, thus at the end of
25 years its supply is nearly exhausted. The
last well to be drilled has been depleted
less than 40 percent and still has several
years supply remaining.

In the other areas, those that are of
particular concern to the Colorado Water Con-
servation Board, the major efforts of the
last few years are studies of the major drain-
age basins, particularly those that involve
the use, the heavy use, of ground water. Our
ground water studies have b~en designed and
keyed toward providing information to the
legislature so they could make wise laws, to
the Colorado Water Conservation Board so they
could make wise plans, to the state engineer's
office and to the Ground Water Commission so
they can administer these laws as wisely as
possible. Our feeling is that having good
information leads to wise planning and admin-
istration.

The problem in these areas is that the
