light on that. 1t seems to me that
this Is apparent
Swendsen-"Have you any fact
ors to take into considerations"
Cowen-''Yes, l have n thing in
mind that l think ought to be taken
some account OF, altho accurate data
in regard to it may be difficult to
obtain; that is, the rain fall thru the
irrigation portion of the season."
Mr.. Cotton asked is there is a sta
ton at Moran. Answered yes.
Cowen-"In going over some OF
these matters with Mr.. Cotton OBJ
serve he makes reference to cond1-
tions that exist during certain sea-
sons and during those seasons these
reports or estimates vary decidedly
from what might be termed a dry
season; that is, the wet portion OF
the year occurring during the irriga-
ton season. mention this as an
element that may be worth taking
into consideration in your investiga-
ton. Your engineer employs this
system in taking observations and
making Investigations of the canal
system. You take the amount OF
water that is delivered at the head
Of the canal; measure that, then
take the water masters report OF
the amount of water delivered to the
users each day, and very naturally
conclude that the amount that is lost
by seepage and evaporation in the
system is the difference between
those two amounts. The same sys-
tenn employed on the river would
not be accurate on account of the
variety of conditions that exist, but
it seems to me that some observa-
tons taken along that line and some
experiments made would be valuable
data to include in any final estimate
of what the losses are. For instance,
suppose you made an experiment In
the middle of the winter, when no
water is being used for irrigation
purposes and no variation IN the
amount measured out; calculate the
difference in the amount you turn In
from the reservoir and the amount
measured thru your various gaging
stations along the river, giving the
water ample time to. get down. Some
information along that line might
assist in arriving at the correct con-
illusions in reference to this. 1t is
perfectly apparent from what has
been done that nc accurate estimate
of it can ever be made. 1t must in
the last analysis be an approxima-
ton and as every element ought to
be taken into consideration, any ex-
pertinent that can be made that
would throw any light on it, if not
too expensive to the water users, in
the way of wasting water, should be
made"
Swendson asked Mr.. Cotton who
had refused to let him examine the
La Rue report.
Cotton-."The state had not re.
fused me permission to examine the
reports, but Mr.. Weymouth had re-
fused to allow examination of the
LaRue reports to the U. S. Reclama.
ton Service. / did not hink you
had a copy or I should have asked
you for them"
Mr.. Swendsen suggested that they
pass on the third proposal if there
were no further comments on the
second.
Mr.. Cotton said that he would like
to know first what. Mr.. Swendson in
tended to do about the second pro-
posal.
Mr.. Swendsen replied that he had
no intention of rendering a decision
today, but would have to give the
matter some study and c%onsidera'
ton.
Cotton-"This is also directed tt
the Advisory Board
Swendsen-"They will sit in OF
the discussion.
Mr.. Cotton added that he woult
like to have Mr.. Swendsen bear ii
mind that it seems the natural waite,
users have been standing the los
in the past years and even tho thu
percentage might be set at a figur'
that might be too high in the frs
year, still they would not be gettin,
any back than they have beel
losing. 49,
Baldwin-"Mr. Cotton has no
given my conclusions any more thai
he mentioned that there was such
thing and I should like to read m,
conclusion in the 1918 report. Con
illusions were that the data was s.
conflicting that it would be impos
sible for me to come to a definit'
conclusion as to what these trans
mission losses are from jackson
Lake to Heise, but l would say the,
, were small; now l wouldn't call Il
per cent very small"
> Cotton-"Well 10 per cent i
smaller than 100 per cent or so pc
cent and you are talking in relativ'
terms, and by referring to the plate
in your reports Of 1917 and 1911
your plate 8 shows an average O
1874 per cent loss; and your plat
9 shows an average loss Of SO pc
cent; your plate IA shows an aver
age loss of SO per cent and plate 1!
shows &c per cent less or a grant
average of 7.2 per cent.
