The purpose of this investigation which is essen-
tially complete is determining supplemental
needs and sources of water supply for approxi-
mately 4,000,000 acres on the east side of San
Joaquin Valley. A possible program for water
supply development will be suggested. Re-
quests for water service from the presently
constructed features for east side San Joaquin
Valley exceed present capacities. Because of
water exchange problems involved in fully
utilizing the available water supply, an overall
evaluation is essential. This study is suffi-
ciently advanced that preliminary planning of
separate segments within the division were
initiated in fiscal year 1978.

Reconnaissance study of the possibilities of sup-
plying water to the potential Eldorado Valley
project, Nevada,, for industrial, municipal,
and irrigation uses to determine if it has suffi-
cient merit to warrant undertaking project
investigation is scheduled to be completed in
fiscal year 1959. A cooperative detailed soil
survey, land classification, and phreatophyte
density study of Virgin River bottom lands in
the Mesquite-Bunkerville areas, Nevada, and
a reconnaissance investigation of the Moapa
Valley pumping project, Nevada, are scheduled
for completion in fiscal year 1960.

Reconnaissance of potential project to provide
for irrigation of 2,100 acres of new lands and
3,700 acres in need of supplemental water to
determine if feasibility investigations are
warranted and to assist State of Wyoming in
selection of projects to use its allotted share of
Colorado River water.

Reconnaissance underway to appraise the possi-
bility of a development on the Yampa River
for irrigation, power generation, and other
uses, utilizing storage at the potential Juniper,
Cross Mountain, and Lily Park Reservoir
sites. This is a priority project under sec. 2,
Public Law 485, 85th Cong., 2d sess. Study
is to be completed in fiscal year 1962.

An inventory of the basin water resources and
study of the potentialities for developing addi-

26, 300 A reconnaissance report was completed in fisca
year 1956 which indicated that additional hy-
drologic data would be needed to reach con-
clusive findings. As a result, a cooperative
program sponsored by the Bureau, the Geo-
logical Survey, and the State of New Mexico
for collection of basic hydrologic data required
for development of a plan for fully utilizing the
available water and land resources of the basin
was initiated.

Study is now underway of the potentialities of
and justification for more detailed studies of
plans for the utilization of flows of Canadian
River for irrigation of 2,200 acres below Eufaula
Dam which is now under construction by the
Corps of Engineers.

The Chehalis River Basin occupies some 2,170
square miles in Pacific, Lewis, Mason, Greys
Harbor, Cowlitz, and Jefferson Counties, Wash.
The area is rapidly outgrowing present water
supplies and plans need to be formulated for
water storage which will provide for the needs
of industry and agriculture. The purpose of
this study is to prepare a basinwide report,
outlining tentative plans for the development
of the basin. In addition to irrigation, all other
facets of the basin resources will be considered
in order to plan for most optimum development.
The report will be completed in fiscal year 1962.
The Clark Fork River, one of the larger tribu-
taries of the Columbia River, has large unde-
veloped storage and power potentialities. In
addition, the basin includes potentially irri-
gable land as well as areas in need of supple-
mental water supplies. A basinwide study is
in progress to inventory the land and water
resources and present a pattern for logical
development. The investigation also will
delineate areas for detailed studies where fea-
sible developments appear possible in the near
future. The present urgent need for additional
power and storage in the Pacific Northwest
gives the study of upstream storage possibilities
added significance. A basin report is scheduled
for completion in fiscal year 1959.
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. The funds
provide for participation in the coordination,
planning, and operation of the Columbia
River and for participation in the International
Joint Commission engineering studies.

Investigation in progress to develop an irrigation
plan to fit into an overall comprehensive plan
of development for the basin, and to coordinate
the plans of the United States with those of
Canada in an international plan of develop-
ment, studies for which are now underway.
Report scheduled for completion in fiscal
year 1960.

The Pend Oreille River Basin, over 100 miles
long and embracing some 3,400 square miles
in the United States, includes an undetermined
area of potentially irrigable land. The basin
is in northern Idaho and northeastern Wash-
ington. The principal purpose of the study is
to determine the potential of the basin which
will aid in formulating an overall compre-
hensive plan of development and outline the
main areas of arable lands that might be worthy
of future irrigation development. The study
is to be initiated in fiscal year 1960 and com-
pleted in fiscal year 1962.
A special report evaluating the basin potential
was completed in fiscal year 1956. This report
was presented to the people of the area in fiscal
year 1957 in order that they might better
determine the course of further specific investi-
gations. Studies in the future will be centered
on specific areas rather than on a basin study.
Funds requested in fiscal year 1959 and fiscal
year 1960 will provide only for the continuance
of the stream-gaging program by the U.S.
Geological Survey.

including the Powder River, and arrive at a
comprehensive 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 produc
tion, and other multipurpose uses and the
integrated use of new facilities with reservoirs
already in operation will be studied. The
study will cover all tributary streams, including
the streams on the north of the basin that
disappear into the basalt flows of the Snake
Plain. Ground-water reservoirs of the basin
are another source of additional water supply
to be considered. Use of land and water
resources in the basin are already developed
in large measure. Formulation of future
development plans must be incorporated into
a basinwide plan in order to assure that future
expansion is orderly and makes full and reason-
able use of the resources. A basin report is
scheduled for completion in fiscal year 1960.
Basin surveys to be initiated or resumed after

tural, and economic factors relating to S. Doc.
113, 81st Cong., 1st sess., entitled "Compre-
hensive Plan for Water Resource Development
Central Valley Basin, Calif." Coordinated
reservoir operation studies are being made with
the State and local groups to insure a coordi-
nated approach to the water development
problems and economic studies kept up to
date. A revision of the report reflecting
changes since S. Doc. 113 (which was com-
pleted in 1945) is expected to be completed in
fiscal year 1965. Studies of salinity conditions
in the delta area of the lower Sacramento River
will be continued.

Investigation in progress to inventory the natural
resources and prepare a plan for their orderly
development in the north coastal area of
California, which contributes approximately
36 percent of the water supply of the State of
California. A report is scheduled for publica-
tion in fiscal year 1960. Funds for transfer to
Fish and Wildlife Service are included for
studies by that agency of the fish and wildlife
aspects of the basin development. This study
has been sufficiently advanced to permit more
detailed studies of the Round Valley unit to
be initiated in fiscal year 1959.
