III lVlO IL was huOWh very carly
that this would be a short water
year and sufficient data was taken to
give record for June as well as July
and August; the average return flow
for June was 2096 sec. it., for July
was $50 sec. it., and for August was
loss of 143 sec. IT. or an average
gain Of SAG sec. IT. (152,2S0 acre IT,
for the 80 days. The loss on stor-
age water for this year was II per
cent as computed by the writer, and
the amount of storage run was 411,-
$50 acre it., this being the first year
that any of the enlarged capacity
was available, the total capacity of
the lake being 426,000 acre IT,, at
this time.
In 1915 the average return flow
for June was 2012 sec. IT,, July was
1913 sec. IT. and August was SS7
; sec. it,, or an average of 1904 sec.
it. equals 270,72O acre it. during
the 80 days. The storage in Jack
son Lake by this time was increased
to $4,000 acre it,; of this 486.740
acre IT.. was run thru Snake river
with loss of S.5 per cent from the
lake at Medley station as given by
D. G.. Martin.
In 1917 the average return flow
for the month of July was 1851 sec.
it,, and in August was rs sec. IT,,
or an average for the two months of
$50 sec. it. 105,960 acre it. in the
60 days.) The storage at Jackson
Lake for this season was $4,000
acre it,, however, 341, 44O acre it.
was retained in the lake, hence only
447,560 acre it. were run and have
not been able to secure a report on
the distribution to know what the
loss on starage was.
! In 1918 the average return flow
for the season as given in D. G. Mar
tins report is 1882 sec. It. Cor 141,-
$40 acre it, for 60 days. The loss
on the 642,1S2 acre it. of storage
run was IA per cent.
| The year 1919 was very dry
year and the average return flow for
the season as given by G. c. Bald
wins report was '29 sec. #. Cor $500
acre it. for the 100 days.; the loss
on the 628,6SO acre it. of storage
run was 13 per cent.
In 1920 the return flow as given
in Mr.. Baldwin's report is 500 Sec
tt. for the season of practically 100
days Cor 100000 acre it. for the 100
days. and the loss on the 62O, 100
acre TT. run was .06 per cent.
The 1921 report was not avail
able when this discussion was
opened but it is understood that the
loss on storage water for 1921 from
Jackson Lake to Woodville was 3
per cent.
Contended Allowance Due
In the light of the above figures
we contend that the natural water
users in the Idaho Falls section
should be allowed 1000 sec. it. as re-
turn flow, which should be added to
their available water on the day fol-
lowing the arrival Of the stored
water. at Blackfoot station.
These figures were arrived at with
stored water in the river and we
contend that the natural water is
made to absorb storage water losses
that should be stood by the storage
interests.
incidentally, while it was not
brought out in the conference, until
1913 there was no credit given the
natural water users for this return
flow altho records indicate that sew
eral years there was considerable
amount
, Open Discussion Follows
Banks: you have been gettins
this return flow just as it is figured
out each day and l think that would
be better than to adopt fiat amount
for the season, as sometime the stor
age water would suffer by this ant
? some time the natural water would
suffer-"
