there are transmountain diversions coming
dO\'ln to the Platte. He \.,ill also kno\." from
our stream regimen studies, that in terms of
firm water supply, that the occasional floods
of the magnitude, or even lesser magnitude,
as occurred in June, these do not really yield
a substantial amount of additional firm water
supply to the basin because of their infre-
quency.

Under the 1958 Water Supply Act we are
required to demonstrate to Congress that we
can yield a firm water supply. We have been
studying this stream regimen by computer
programs- machine computer programs - for about
two years now trying to substantiate that there
is a firm water supply and the frequency of it.
The frequency of floodings are the magnitude
that could yield some additional firm water
supply. From our studies there is about once
in a hundred years or a probability of one per-
cent for the opportunity of catching sufficient
water to impound and add to the water supply.
But then, when you spread this out, or when you
relate it to statistical probabilities, there
isn't a great deal of firm water supply that
you can get out of the South Platte Basin that
is not already appropriated."

"Hell, I think the residents of these
flooded areas are not the least bit interested
in statistics."

"I reali'3e that."

"And the people that are coming back into
these areas to rebuild their homes, their busi-
nesses and their farms must h~ve some assurance
that something can be done before 1969. Now
I have an impression, and you and I have
chatted briefly about these things, that in
the Denver area, in addition to not having the
Chatfield Dam, you had a lot of marginal homes,
trailer parJ\:s, industries, all the way down the
channel that swept down the river into what I
consider most inadequate bridges, damming the
