<br />
<br />Hunler Tunnel: Hunler Tuunel will be 7.6 miles long. It
<br />will transporllhe flows diverted al No Name, Midway,
<br />and Hunter Creeks 10 Chapman Gulch allhe Cbapman
<br />Diversion Dam. The design capacily ranges from 90
<br />cubic feel per second al No Name Creek, Ihe poinl of Ihe
<br />beginning of the South Side Collection System, to Mid-
<br />way Creek with 270 cubic feet per second at Chapman
<br />Gulch on the Chapman diversion site. No Name, Mid-
<br />way, and the Hunter Creeks diversion structures are all
<br />similar. Each has a sluicegate for hypassing all stream-
<br />flow when water is not heing diverted. When diversions
<br />are heing made, minimum flow will he released through
<br />a bypass to maintain the stream. A side overflow section
<br />provides for passing floodflows. Flows will he diverted
<br />through a short flume section to a shaft which will drop
<br />the water into Ihe Hunter Tunnel. Hunter Tunnel is a
<br />semihorseshoe-shaped structure with two sizes: 8.5 and
<br />7.33 feel.
<br />
<br />Chapman Tunnel: The Sawyer diversion drop inlet
<br />diverts water from Sawyer Lake into Sawyer Feeder Con-
<br />duit (3,098 feet in length), and drops the water at Chap-
<br />man Gulch. The water then flows to Chapman Diversion
<br />Dam, with the flow from Hunter Tunnel, to be diverted
<br />into Cbapman Tunnel. Chapman Tunnel is a 2.8-mile-
<br />long, 7-foot horseshoe-shaped structure, with a capacity
<br />of 300 cubic feet per second.
<br />
<br />South Fork Tunnel: The South Fork Diversion Dam
<br />diverts water from South Fork Creek to the South Fork
<br />Siphon, where it continues with the flow from the South
<br />Fork Creek and is conveyed by the South Fork Feeder
<br />Conduit to the inlet of the South Fork Tunnel.. The
<br />South Fork Tunnel is a 3.1-mile-long, 8-foot horseshoe-
<br />shaped section, and has a capacity of 450 cubic feet per
<br />second. Tbe tunnel discharges water into the Charles H.
<br />Boustead Tunnel. The Fryingpan Diversion Dam diverts
<br />water into the Fryingpan Siphon under the Fryingpan
<br />River to the inlet structure at Charles H. Boustead
<br />Tunnel.
<br />
<br />Charles H. Boustead Tunnel: The Charles H. Boustead
<br />Tunnel conveys all the water collected at the Fryingpan
<br />diversion and in the North and Soutb Side Collection
<br />Systems under tbe Continental Divide and into Tur-
<br />quoise Lake. The 10.5-foot-diameter, horseshoe-shaped
<br />tunnel is approximately 5.4 miles long. The capacity of
<br />the tunnel is 945 cuhic feet per second. The Fryingpan
<br />Valley control structure at the inlet portal of the tunnel
<br />will regulate flows entering the Charles H. Boustead
<br />Tunnel. It is a concrete junction structure which contains
<br />two overflow weirs, one for each of the collection sys-
<br />tems, a baffled apron wasteway drop structure to return
<br />the excess flows to the Fryingpan River, a connection
<br />and access hatchway structure to receive the flows from
<br />
<br />the Fryingpan Feeder Conduit, and a control structure
<br />housing a 10.5- by 12-foot radial gate. The entire struc-
<br />ture is u?derground.
<br />
<br />Mt. Elb~rt Conduit: Mt. Elbert Conduit will convey
<br />project "fater from Sugar Loaf Dam to the Mt. Elbert
<br />Forebay.l Water delivered to the forebay will be used for
<br />the generation of power in the Mt. Elbert Pumped-
<br />Storage Powerplant. At Halfmoon Creek, additional
<br />water will he diverted to the conduit for delivery to the
<br />Mt. Elbert Forebay. A pipe turnout and conduit will
<br />deliver supplemental water from the conduit to the Lead-
<br />ville Natlonal Fish Hatchery. The conduit will be a
<br />90-inch-4iameter pipe, 10.7 miles long, and designed for
<br />a flow o~ 370 cubic feet per second from Sugar Loaf Dam
<br />to the foi-ebay. It will consist of a series of siphon and
<br />free-flow: conduit reaches. The Halfmoon Diversion Dam
<br />will intercept the excess flows of the Halfmoon Creek for
<br />diversion to Mt. Elbert Conduit. The diversion dam will
<br />consist of a concrete spillway overflow structure, earth
<br />wing dikjl structures, a gated concrete structure to bypass
<br />irrigatioQ flows, for downstream use, and a heading for a
<br />feeder cdnduit. The Halfmoon Feeder Conduit will be a
<br />60-inch-4iameter pipe, 3,202 feet long, and will deliver
<br />the flow..diverted at Halfmoon Creek to the Mt. Elbert
<br />Conduit.' Flow capacity of the feeder conduit will be 150
<br />cubic feet per second.
<br />
<br />Fountain Valley Conduit: The Fountain Valley Conduit
<br />will begin at Pueblo Dam, about 6 miles west of Pueblo,
<br />and end ~ear Academy Boulevard, about 2 miles south of
<br />Colorado Springs. The conduit will convey approximately
<br />20,100 a~re-feet of project water annually to the com-
<br />munities i of Stratmoore Hills, Widefield, Security, and
<br />Fountai~. The Fountain Valley Conduit will be 45 miles
<br />long and' will range from a 42- to 14-inch-diameter con-
<br />duit. It will have five pumping plants, two regulating
<br />tanks, two surge tanks, and four terminal tanks. The
<br />capacity jwill be 31 cubic feet per second.
<br />
<br />Otero c1'nal: Otero Canal will carry water from Twin
<br />Lakes to the Otero Powerplant and the Homestake Turn-
<br />out near the powerplant intake structure. The canal will
<br />be 5.5 miles long; of this, 0.7 mile will be a bench flume,
<br />0.2 mile a pipe siphon, 0.3 mile a tunnel, and the re-
<br />maining 4.3 miles will be an open trapezoidal concrete-
<br />lined canal section, The canal will have a capacity of 725
<br />cubic feet per second.

<br />The Mt.! Elbert Pumped-Storage Powerplant is on the
<br />north shbre of picturesque Twin Lakes, approximately
<br />13 miles southwest of Leadville, Colo., at the foot of
<br />14,433-foot Mt. Elbert, Colorado's highest mountain
<br />peak. T4e powerplant was designed with modern archi-
<br />tectmal ~ines and is an allRconcrete structure equivalent
