Bear Creek, San Joaquin County, $67,000 to complete. Insert pages 22 and 23.

(The justification follows:)

BEAR CREEK, SAN JOAQUIN COUNTY, CALIFORSTA (Continuation of Planning)

LOCATION AND DESCRIPTION: The project extends from about 2 miles south of the town of Lockeford, California
along Bear Creek to Disappointment Slough, a delta channel which comects with San Joaquin River. It
provides for construction of about 40 miles of low levees and 19 miles of chamel improvement.

JUSTIFICATION: This project will provide a high degree of flood protection to an area which is flooded, at
least in part, on an average of three out of four years. The area to be protected includes about 30,000
acres of highly developed orchards, vineyards, and row croplands; suburban areas adjacent to the city of
Stockton which are now unprotected against all but minor flows; and main highways, railways, and industries.
The 1958 floods caused damages in the project area estimated at $600,000 at then prevailing prices.
With recurrence of that flood under current conditions of development and price levels these damages would
amount to $675,000 all preventable by construction of the project. Annual Lood-control benefits for the
project are estimated at $400,000. About 7,200 people currently reside within the project ares and the valus
of land and improvements to be protected is estimated at about $53,000,000. Rapid and extensive suburban
encroachment onto highly-developed agricultural lands within the project area indicates necessity for
prompt construction of the project.

OROVILLE RESERVOIR

Mr. RABAUT. Oroville Reservoir, $25,000.

Insert pages 25 and 26.

(The justification follows:)

OROVILLE RESERVOIR, CALIFORNIA

(Continuation of Planning)

LOCATION AND DESCRIPTION: The project is located on Feather River, a tributary of the Sacramento River in
Butte County, California, about 4 miles east of the town of Oroville. The plan of improvement provides for
a Federal contribution for flood protection to be afforded by construction and operation of Oroville
Reservoir by the State of California for water supply, power generation, irrigation, flood control, and
other purposes.

Tentative estimate pending final review of cost allocation studies.

JUSTIFICATION: The project will provide flood protection to the cities of Marysville (population 9,650), Yuba
City (population 11,400) and Oroville (population 6,022); to many small communities in the flood plain; to
283,000 acres of highly developed agricultural land; and to important highway and railroad routes. If the
project had been completed and in operation during the December 1955-January 1956 floods, it would have pre-
vented the flooding of Yuba City, Yuba City agricultural area, and the Nicolaus area. Such a reduction in
flood flows in Feather River would also have relieved the threat to the remaining portion of the Sacramento
River levees system below the mouth of Feather River. During the December 1955-January 1956 floods, forty
lives were lost and damages amounting to about $50,500,000 occurred in the area below the Oroville dam site.
Under current conditions of development and price levels, these damages would amount to $62,900,000 of which
$61,150,000 would be preventable by construction of the project. Average annual flood damage reduction is
estimated at $3,640,000.
