Funds are required for Columbia River Basin
studies for comprehensive plans, particularly
for power and flood control, for important
Army and Reclamation dams in operation
and under construction or authorized; and
in connection with Reclamation's responsi-
bilities stemming from the Army-Interior
agreement on comprehensive development of
the Columbia River Basin, and also partici-
pation in the coordination and planning of
the Columbia Basin Interagency Committee.
In fiscal year 1957, funds are also included for
work in cooperation with the Corps of Engi-
neers in bringing up to date its comprehensive
report on the basin.

Investigation scheduled to be undertaken in
fiscal year 1957 to develop an irrigation plan
to fit into an overall comprehensive plan of
development for the basin, and to fit the plans
of the United States in with those of Canada
in an international plan of development,
studies for which are now under way.
544, 792 Investigation in progress. The purpose of this
investigation is to evaluate the undeveloped
land and water supply potential of the upper
Snake River Basin and arrive at a comprehen-
sive multipurpose development plan. The
amount and distribution of water supply
available for irrigation of new lands and as
a supplemental supply for the lands that are
now inadequately irrigated will be covered.
Domestic supplies, flood control, power pro-
duction, and other multipurpose uses and the
integrated use of new facilities with reser-
voirs already in operation will be studied.
Ground-water reservoirs of the basin are
another source of additional water supply to

Upper and Middle Snake River
Basin.

Collection of water supply data in progress.
Investigation to be started in fiscal year 1957
to determine feasibility of irrigation of 80,000
acres of new land.

21, 165 Public Law 577 passed in 1952 reauthorized the
Chief Joseph Dam project to include irriga-
tion among its multiple purposes. Con-
struction of this dam is now nearing comple-
tion. Several areas in the vicinity of the dam
have an irrigation potential that should be
studied. In fiscal year 1956, studies on the
Greater Wenatchee division will be com-
pleted; this division could provide a full
water supply to about 9,000 acres of land and
a supplemental supply to 1,650 acres. Studies
will be initiated on the Okanogan-Simil-
kameen division to develop a plan for serving
irrigation water to about 7,200 acres of new
land and providing supplemental water to
about 19,800 acres now suffering from chronic
shortages which threaten to become worse
due to upstream developments in Canada.
In fiscal year 1957, studies of the Okanogan-
Similkameen division will be completed and
studies of the Chelan division to serve about
2,000 acres of new land and 3,800 acres of
presently irrigated land and the Alameda
unit of the Shoreline pumping division to
serve about 2,000 acres of new land should be
started.

Reconnaissance of area has been made. Studies
started in fiscal year 1955 to determine feasi-
bility of providing irrigation water to about
10,000 acres of land as the initial development
of an overall area of 80,300 acres. Report
scheduled for completion in fiscal year 1957.

tigation started in fiscal year 1955 to examine
possibilities of developing about 4,400 acres
of new land. Report scheduled for comple-
tion in fiscal year 1957.

Investigation scheduled to be resumed in fiscal
year 1956 to develop plans to provide a firm
water supply to about 4,000 acres of land now
badly in need of late season irrigation.
Investigation, which has strong local support,
would be completed early in fiscal year 1958.
Reconnaissance of area has been made. Studies
started in fiscal year 1955 to determine
feasibility of providing supplemental water
to about 6,000 acres of land. Report
scheduled for completion in fiscal year 1957.
Investigation in progress to determine feasi-
bility of providing needed supplemental
water to 3,300 acres of land and providing a
full supply to about 5,800 acres of land by
pumping from pool behind McNary Dam.
Report will be completed during fiscal year
1956.
47, 383 Investigation to develop plan for the irrigation
of some 41,000 acres of new land scheduled
to be started in fiscal year 1957. Area is in
need of late summer irrigation water to
insure maximum yield from land. Water
would be obtained from storage on Molalla
River.

Investigation to be started and completed in
fiscal year 1956. The construction of a re-
regulating reservoir below Palisades would
increase power value at Palisades by per-
mitting unrestricted peaking, provide a
means for closely controlling the irrigation
releases, provide for generation of 45,000
kilowatts of additional power, and enhance
fishing and recreation.

7,150 Reconnaissance of area made. Investigation
to determine plan for the development of
3,000 acres of new land by diversion from
pool behind existing McNary Dam scheduled
to be undertaken in fiscal year 1957.

Proposed report on this project completed.
Completion of final report scheduled for
fiscal year 1956. Plan would provide a full
irrigation supply to some 35,500 acres of dry
land.

Proposed report has been completed. Small
amount of funds required in fiscal year 1956
for preparation of the final report. Project
will supply water for about 1,300 acres.
