storage itself, it falls into two phases. First, storage to

equate the flow seasonally in the terms of flood control,

.

as we refer to. them, and second, to equate the water over a

term of years. Roughly, without any accuracY, the storage

.

required for seasonal control is probably somewhere between

5 or 6 million acre feet. The storage required to equate over

a term of years is probably say 10 million acre feet. I am not

pronouncing this as final terms. If storage were provided in the

river for perhaps in the lower basin of 18 million feet, or

somewhere thereabouts, we would have an equation of the river

over a long period and in order to arrive at an average delivery

over a term of years~ such as ten years, that equation is nec-

essary.in order to give an assurance of regular flow. Now, if

the paot were made conditional upon the erection of that

..

storage at some point, ( I am not finding any point), but some

.

point that would serve the lower basin, t:,en,. it would not seem

to me to be necessary to arrive at a minimum annual flow, but

that the whole flow could then be - that the one single

quantitative figure would be necessary. fir. Caldwell was think-

ing on that Sarno line, it is his original thought, in suggest-

ing that there should bo in tho uppor basin 6 million foot of

storage~. a minimum of that, in ordor to enable that basin to

equate tho flow ovor a term of. years, I assume. what he had in

.

mind wa~ storage against the annual fluctuations rather than

.

the sea~onal control. Whether that storage is in the upper or

in the lower basin, it seems to me to be immaterial whethor we
