The Greater Wenatchee division of the Chief
Joseph Dam project, consisting of 4 units-
East, Brays Landing, Howard Flat, and Moses
Coulee was authorized on May 5, 1958. The
4 units total some 8,661 acres, of which 7,221 are
nonirrigated. The development of an irriga-
tion water supply for the division is urgently
needed to replace land that will be or has been
lost through subdivision of apple orchards for
housing areas, the construction of a new high-
way through the division, and the potential
construction of Rocky Reach and Wells Dams.
The development of new agriculture land will
also serve as the primary factor in the expansion
of the economics of the area. A definite plan
report will be completed in fiscal year 1959.

The Washoe project will provide supplemental
water for irrigation to 44,500 acres of land in
need of dependable late season water supply
and a full supply for some 5,100 acres of pres-
ently undeveloped arable land. Control of the
high spring runoff will reduce flood damage and
with project drainage will improve 30,900 acres
of presently waterlogged land. The project
also will produce 28,000 kilowatts of hydroelec-
tric power greatly needed in western Nevada.
The fiscal year 1959 Appropriation Act pro-
vided funds for initiation of construction on
Prosser Creek Dam and Reservoir of this proj-
ect and these general investigation funds will
finance continuation of detailed preconstruc-
tion studies on the balance of the project. The
definite plan report is scheduled to be com-
pleted in fiscal year 1960.

Advance planning studies to be initiated after
fiscal year 1960.

Detailed preconstruction studies were interrupted
in 1954 by a decision by local interests to
explore possibility of proceeding with private
financing. These efforts were unsuccessful and
the local interests have since expressed interest
in a Federal development and have contributed
funds toward completing the preconstruction
work. A definite plan report is to be com-
pleted in fiscal year 1960.

Detailed preconstruction studies were underway
at the end of fiscal year 1958. The fiscal year
1959 program provided for the continuation of
this work until about September 1958 when an
allotment of construction funds was made
available by the 1959 Public Works Appro-
priation Act.
The funds programed for fiscal year 1959 provided
for the continuation until about September
1958 of detailed preconstruction studies which
were financed with appropriated funds and
funds contributed by local interests. Work
under the general investigation activity was
terminated last September when an allotment
of construction funds was made available.

Investigation of irrigation features of a multiple-
purpose project proposed by the Corps of
Engineers to be constructed primarily for flood
control and irrigation. Authorizing legislation
was passed by the 85th Cong. and signed by
the President July 23, 1958. The project is
urgently needed to provide protection from a

5,046, 896

serious and longstanding flood problem and for
regulation and conservation of waters of the
Purgatoire River for more beneficial and
efficient irrigation use. During fiscal year
1959 a detailed report will be drafted on irriga-
tion and repayment phases of the project.
After completion of the report in August 1959,
the program will be limited to cooperation
with the Corps of Engineers and water users
in the area.

Investigation should be made in fiscal year 1959
to determine means and probable cost of in-
creasing the capacity of the Payette division
irrigation system to deliver more water to
project lands.

Many of the structures of this project have
deteriorated over the more than 40 years that
the project has been in operation to the point
where they are in immediate danger of failure
or the cost of maintenance is prohibitively
high. Replacement of these structures is be-
yond the financial ability of the water users.
A study is to be made in fiscal year 1960 to
determine the project needs and develop a
rehabilitation program to place the project in
a satisfactory and safe operating condition.
The existing Vermejo diversion dam was con-
structed about 1914, is of questionable struc-
tural stability, and has its crest about 2 feet
lower than required to permit diversion of
flows to the capacity of the main canal. Fiscal
year 1960 funds scheduled would be used to
initiate and complete a study of the feasibility
of plans for raising the crest of the Vermejo
diversion dam 2 feet by modification or replace-
ment of the existing dam.

10,000 Reports on field reclassification of class 5 lands
in Malta, Glasgow, and Chinook divisions, as
provided for in Public Law 402, 82d Congress,
2d session, will be completed, Miscellaneous
related work will be continued in connection
with the terms of the amendatory contracts.
This study is to be completed in fiscal year
1960. Investigation for determining the cost of
increasing the storage capacity of Fresno Dam
and Reservoir is scheduled in future years.

Devil Canyon project is a potential source for
a large block of power (450,000 kilowatts ulti-
mate) that could serve the railbelt area from
Seward to Fairbanks. Ample available energy
would stimulate and afford an opportunity for
industrial development and related growth
throughout this section of Alaska.
Studies are underway, in cooperation with the
U.S. Department of Agriculture and the Alaska
Agriculture Experimental Station in conjunc-
tion with the Soil Conservation Service, to
determine crop-yield benefits that may be
derived through irrigation as a basis for es-
tablishing feasibility for developing an irriga-
tion system to serve the Matanuska area.
