from Mr, Grover who is the Chief Hydrographer of the Geological

Survey, on inflow. It isn't complete, but I can allow for the

lack, Mr. Grover estimates the ~aria River an average flow of
60,000 acre feet; Kanab Creek, 30,000; Little Colorado River,

200,000; Virgin River, 233,000; Williams River 75,000, These

are most of them based upon meagre measurements and while in-

di'lidua11y I would from my own m'j'mory make some corrections,I

would arrive at nearly the same conclusion as Mr, Grover does,

excepting that he has entirely omitted all of the areas except

those five streruns while they include only about 2/3 of the

drainage area, To complete it on the same basis, assuming that

the little streams not included in these five principal streams,

flow at the same average per square mile, it would bring the

amount up to just a little over 1,000,000 acre feet, which is

practically the same as our estimated l~sses, before any fifty-

fifty proposition was suggested ,between Boulder Coo1yon and Yuma.

I think probably the 1500 secon4 feet loss between Boulder and

Yuma was large but certainly the excess was not more than

enough to balance the rest of the canyon. The losses in the

canyon are relatively small, and the losses belml are great

because of the broad expanse covered by water.

MR. NORVmL: Mr. Davis, one more question, Assuming you

have read this compact, or heard it read, and understand its

purports, does it contemplate ~ecessari1y the construction of

a. large dam in the lower river and the storage of ~~ter and

stabil:Lzing the flow of the river in order that the lands in the
