STATUS OF AFFAIRS ON BOISE
RECLAMATION PROJECT
Power, Development and Progress OF
Work Discussed by Record.

The Boise project will have ample
power. A high masonry storage dam
about 240 feet above the river bed has
been built at Arrowrock. More than
100000 acre feet of water have to
pass this dam every year, all of which
is used for irrigation in minimum years
but III ordinary years there is consid-
cradle surplus.
Power development at this dam
could utilize the head in the reservoir
which varies from ~ to 230 feet. The
quantity of water available during the
summer would be about 5000 cubic
feet per second which would be di-
minished in the spring and fall, and in
the winter only about 200 cubic feet
per second could be drawn.
Provision has been made for the
convenient installation of power to the
extent of 1900 horsepower at this
site. A greater amount could be de-
veloped during the summer if found
desirable.
Storage Conditions.
The Reclamation Record reports
storage conditions on the Boise pro-
ject for April as follows:
Arrowrock-Available capacity in
acre-feet, $4,000; storage in acre-feet
beginning of month, 69,o5O; end of
month, 150,810; maximum, l50,810;
outflow in acre-feet, 352,47O; elevation
of water surface beginning of month,
3,ll2.l; end of month, 1854; maxi
mum, 1854.
Deer Flat - Available capacity in
acre-feet. 1861; storage in acre-feet
beginning of month. 67,088; end OF
month. TAO; maximum, 85,247; out
flow, 1925; elevation of water surface
beginning of month, 2,504.1; end OF
month, z. 505.6; maximum, 2,5O68.
The month of April began with ap-
proximately 1900 second-feet in the
Main canal and ended with a diversion
of 1000 secondfeet.
Irrigation began shortly after the
first of April and water was run through
the entire lateral system during the
month The use was unusually heavy
and before the end of the month many
of the laterals were carrying their full
capacity.
The principal maintenance jobs dur
ing the month were the repairing OF
one break in the Deer Flat Low Line
which required about IL teams for
three days. and break in the Mora
Sdildl, WHICH Was repaired III dOOul
one-half day. Considerable repair
work was required also for timber
structures.
April was exceptionally dry and
windy and number of frosts were re-
corded. There have not been enough
spring rains to start the crops in first
class condition. though it is hoped
these rains will come later.
Construction Work.
Construction work was somewhat
reduced in April and portion of the
crews were transferred to operation
and maintenance work. The following
construction work was accomplished
during the month: "a concrete and ma.
sonry drops: concrete and masonry
checks; concrete and masonry weirs
concrete "V" chutes, 2,237 linear
feet; 800 cubic yards concrete in Liz
ard wasteway, 100 per cent completed
u cubic yards concrete in Richards
point wasteway. 40@o completed; lOt
cubic yards concrete lining, 270 cubic
yards; S metal fumes, 286 linear feet
feet; 1876 small timber structures; 2,80(
linear feet lateral construction.
The four drag line excavators were
continued the entire month with goot
progress.
