AGENCY:
SUMMARY: In accordance with Section
204 of the 1950 Flood Control Act (Pub.
L. 516, 81st Congress, 2nd Session), as
recommended by the Chief of Engineers
in House Document Number 585, 81st
Congress, 2nd Session, the Coyote Dam
(also known as the ‘‘Lake Mendocino
Project’’), Ukiah, CA, is authorized to be
raised 36 feet to a total storage capacity
of 199,000 acre-feet (ac-ft) when the
need for additional water supply arises.
Since construction of Coyote Dam,
increased development of Mendocino
County and the accelerated rate of
sedimentation in Lake Mendocino have
resulted in the need for additional water
supply. The additional storage capacity
achieved by raising the dam would
address future demands on water
supply and also increase flood damage
reduction functions. This is a notice of
intent to prepare a joint environmental
Impact Statement/Environmental
Impact Report (EIS/EIR), and to consider
all reasonable alternatives, evaluate
potential impacts of the proposed
action, and identify appropriate
mitigation measures. The U.S. Army
Corps of Engineers (Corps) is the lead
agency for this project under the
National Environmental Policy Act
(NEPA), and the Mendocino County
Inland Water and Power Commission
(IWPC) is the lead agency and local
sponsor under the California
environmental quality Act (CEQA).
DATES: A public scoping meeting will be
held on April 26, 2007 from 7 p.m. to
9 p.m.
ADDRESSES: The scoping meeting will be
held at the Ukiah Valley Conference
Center, Cabernet Room 1, 200 South
School Street, Ukiah, CA 95482.

SUPPLEMENTARY INFORMATION: Coyote
Dam is located on the East Fork of the
Russian River, Ukiah, CA, and is part of
a system that provides water to
Mendocino, Sonoma, and Marin
counties. The Congressional
authorization for construction of Coyote
Dam included provisions for increase in
water storage capacity by raising the
dam an additional 36 feet, thereby
increasing the total storage capacity
from 122,500 ac-ft to 199,000 ac-ft. The
dam was designed to be built in two
stages: the initial stage was completed
in 1959, and the second stage would be
built when water storage capacity
became inadequate. The growth of
Mendocino County has contributed to
an expanded need for water in order to
meet future demands. In addition, the
accelerated rate of sedimentation in
Lake Mendocino further impacts the
storage capacity of the dam by
encroaching on the water supply pool.
The goal of the project is to provide
increased water storage capacity and
increased flood damage reduction
benefits to the area. the local sponsor for
the project is the Mendocino County
Inland Water and Power Commission
(IWPC), a Joint Powers Authority
representing the County of Mendocino,
the City of Ukiah, Mendocino County
Russian River Flood Control and Water
Conservation Improvement District,
Redwood Valley County Water District,
and the Potter Valley Irrigation District.
1. Proposed Action. Based on the need
for additional water supply and flood
damage reduction benefits, it is
determined that increased water storage
capacity at Coyote Dam should be
evaluated.
2. Project Alternatives. The following
are some of the alternatives that will be
evaluated in the EIS/EIR:
a. Raise the dam. Following the
original plans of the authorized project,
the dam would be raised 36 feet to an
elevation of 820 feet, increasing the
storage capacity from 122,400 ac-ft to
199,000 ac-ft. Some provisions were
made on various features of the existing
dam to accommodate the future height
increase.
b. Increase seasonal water supply
storage elevation. Utilizing the existing
dam and reservoir area, the water
surface elevation of the flood control
pool would be raised from 748.0 to
761.8 for seasonal use between April 1
and October 15. This would provide an
additional 25,700 ac-ft of storage.
Although the Corps has authority over
the flood control pool, the Mendocino
County IWPC must demonstrate that the
PO 00000
Frm 00050
Fmt 4703
Sfmt 4703
extra storage capacity is needed for
current demands and would not result
in an excess storage of water, which
would unnecessarily flood recreational
areas and access roads situated at
elevation 750.
c. Dredging. Of the original 122,400
ac-ft storage capacity, 4,400 ac-ft was
allocated for sedimentation, but the
capacity of Lake Mendocino has since
decreased to 116,470 ac-ft. The rate of
sedimentation is higher than the
estimate provided by the original
sediment study. This alternative would
increase storage capacity by dredging
sediment from the reservoir. Dredging is
not expected to affect current reservoir
operations.
3. Scoping Process. The Corps is
seeking participation of all interested
federal, state, and local agencies, Native
American groups, and other concerned
private organizations or individuals
through this public notice. The public
scoping meeting will be held in Ukiah,
CA (see DATES). Any changes to the date,
time, or location will be published in
the newspaper or provided by mail to
those requesting information. The
purpose of the meeting is to solicit
comments and questions regarding the
potential impacts, environmental issues,
and alternatives associated with the
proposed action. Public participation
will help to define the scope of the
environmental analysis in the EIS/EIR;
identify other significant issues; provide
other relevant information; and
recommend mitigation measures. The
public comment period closes on May
10, 2007.
4. Availability of EIS. The public will
have an additional opportunity to
comment on project alternatives once
the draft EIS/EIR is released.
