Operations
of the Central District
 
The
Central District is a political subdivision
of the State of Nebraska with headquarters
in Holdrege. It is governed by
a
15-member board of directors elected from Gosper, Phelps, Kearney,
Adams, Keith, Lincoln and Dawson counties. Directors are elected
to serve six-year terms. Central's hydroelectric facilities are
licensed by the Federal Energy Regulatory Commission.
The Central District is organized as two major divisions for the
purposes of operation. The Irrigation Division headquarters are
located in Holdrege with offices in Minden and Bertrand. The Hydro
Division is located at Gothenburg. A branch office of the Gothenburg
Division is also maintained at Kingsley Dam near Ogallala. Central's
administrative headquarters are in Holdrege.
Central's
facilities begin with its main storage reservoir, Lake McConaughy.
Formed by Kingsley Dam, a 3.1-mile-long hydraulic fill dam across
the North Platte River, Lake McConaughy is Nebraska's largest reservoir
with a storage capacity of almost 2 million acre-feet. The lake
is 22 miles long, more than three miles wide and covers 30,500 acres
at maximum fill.
Water
released from Lake McConaughy flows through Lake Ogallala to the
Nebraska Public Power District's (NPPD) Keystone Diversion Dam.
Here the water can be diverted into NPPD's canal or passed through
the dam down the North Platte River. Water which flows through NPPD's
system is returned to the South Platte River just above Central's
Diversion Dam 50 miles east of Lake McConaughy below the confluence
of the North and South Platte Rivers.
Central's
Diversion Dam, an 874-foot-long concrete and steel structure, diverts
water through the headgates of the Supply Canal, or can pass water
down river. The 75-mile-long Supply Canal delivers water to Central's
three main irrigation canals, E65, E67 and Phelps, which serve a
total of more than 105,000 acres in Gosper, Phelps and Kearney counties,
while another 7,500 acres in Lincoln and Dawson counties receive
irrigation service directly from the Supply Canal.
Central's
delivery system includes more than 500 miles of canals, laterals
and pipelines. The E65 Canal starts just above the inlet to Johnson
Lake and the E67 Canal branches off the Supply Canal just below
the lake. The two canal systems serve about 48,000 acres in Gosper
and western Phelps counties. Central's irrigation office in Bertrand
is responsible for maintenance and irrigation service on the E65
and E67 systems.
Elwood
Reservoir, which was added to the system in 1976 as part of a major
rehabilitation project, provides supplemental storage water to the
E65 canal system. The reservoir is filled prior to the irriga tion
season by pumping water through the Carl T. Curtis Pump Station.
The reservoir has an operational capacity of 24,715 acre-feet and
a total capacity of more than 40,000 acre-feet.
Irrigation
offices in Holdrege and Minden provide maintenance and irrigation
services along the Phelps Canal system. The Holdrege office is responsible
for approximately 31,600 acres in Phelps County and the Minden office
serves about 25,600 acres in Kearney County.
The
system also provides documented ground water recharge benefits to
more than 310,000 acres in and adjacent to the project area. These
recharge benefits are recognized within the District's U-2 and U-12
incidental underground storage water rights. In addition, supplemental
irrigation benefits are provided to irrigation companies serving
lands along the North Platte River between Kingsley Dam and North
Platte and downstream on the Platte River to Kearney.
As
water travels through the Supply Canal, it produces power at the
Jeffrey, Johnson No. 1 and Johnson No. 2 hydroplants, each with
an electrical generation capacity of 18,000 kilowatts. The three
hydroplants are unmanned and remotely operated from the Gothenburg
Control Center. With the addition of the 50,000-kilowatt Kingsley
Hydro in 1984, also operated from Gothenburg, water flowing through
Central's system can generate up to 104,000 kilowatts of electricity.
All power generated at Central's hydro facilities is sold to NPPD
for distribution to electrical customers.
In
addition to the hydroplants, the Control Center maintains remote
supervisory control over NPPD's Keystone Dam and supply canal headgates,
all control structures on Central's Supply Canal, the headgates
of the main irrigation canals and control structures on the E65
and Phelps irrigation systems.
Central's
project also provides a wide variety of recreational opportunities
and habitat for wildlife. The Lake McConaughy/Lake Ogallala area
attracts vacationers and tourists who spend approximately 750,000
visitor-days annually at the lakes. The Nebraska Game and Parks
Commission (NGPC) manages State Recreation Areas at the lakes and
the Clear Creek Wildlife Management Area at the west end of Lake
McConaughy.
Twenty-six
lakes, ranging in size from less than one acre to more than 2,500
acres, are located along the Supply Canal, providing abundant recreational
opportunities and wildlife habitat. Recreation areas managed by
the NGPC are available to the public at Gallagher and Johnson lakes
and wildlife management areas are located near Box Elder, Cottonwood,
Midway and East Phillips lakes.
Central's
lakes also provide benefits to owners of approximately 1,100 private
homes and cabins which are situated on District property around
McConaughy, Jeffrey, Midway, Plum Creek and Johnson lakes.
Through
cooperation with the NGPC as well as private developers, Central's
facilities provide significant contributions to the State of Nebraska
in terms of recreation and wildlife habitat. Central's lakes cover
a total of 35,688 surface acres of water, the basis of associated
benefits to recreation and wildlife. Approximately 5,900 acres of
land adjacent to Central's lakes are managed by the NGPC as State
Recreation Areas and about 6,800 acres are designated as Wildlife
Management Areas. |
