<br />West, The reservoir maximum water surface would be elevation
<br />8,960 and the storage volume 100,000 acre-feet of water, Con-
<br />struction of the reservoir would require relocation of 2,5 miles
<br />of U. S. Highway 24, 2.3 miles of 115 kV electrical transmission
<br />line and 2.4 miles of telephone line. Additionally, 3.7 miles of
<br />new road would be required along the shore line of the new
<br />reservoir for access to Homestake Valley, Costs would be shared
<br />equally by the Cities and the CRWCD. Plan F-1 does not con-
<br />template any use of the Iron Mountain Reservoir by the DWB.
<br />
<br />c. A diversion structure on the Eagle River near the southeast
<br />corner of Section 4, Township 7 South, and Range 80 West,
<br />From the diversion structure, a 96 inch gravity pipeline would
<br />extend northwesterly 6,600 feet to the west quarter corner of
<br />Section 4, Township 7 South, Range 80 West to discharge to a
<br />drainage course tributary to Iron Mountain Reservoir. Costs
<br />would be prorated 26 per cent to the Cities and 74 per cent to
<br />the CRWCD. Plan F-1 does not contemplate any DWB use of
<br />these diversion facilities.
<br />
<br />d, A 52 mgd pumping station in Homestake Valley, located
<br />immediately downstream of Iron Mountain Dam. This station
<br />would pump from the reservoir and discharge to a tunnel and
<br />pipeline system to be constructed jointly, in part, with the DWB.
<br />The reservoir would permit year.round pumping at a uniform
<br />rate of 37 mgd. Under Plan F.1, the pumping head would
<br />average 500 feet as contrasted with 1,300 feet under Plan D,
<br />1,400 feet under Plan E, and 510 feet under Plan F.
<br />
<br />A new electrical transmission line would be required to supply
<br />electric power to the pumping station, This would connect to
<br />the relocated 115 kV transmission line presently paralleling U, S.
<br />Highway 24, The Cities would bear all costs for the pumping
<br />station as CRWCD allocations would be discharged by gravity
<br />from the reservoir to downstream power and/or other uses.
<br />
<br />e. A system of tunnels and pipelines extending from the pump-
<br />ing station northeasterly 88,000 feet to discharge into Ten Mile
<br />Creek tributary to the DWB Dillon Reservoir.

<br />Commencing at the pumping station in 7-d, a 48 inch pipeline
<br />would extend 5,000 feet to a point in the southwest quarter of
<br />Section 20, Township 6 South, Range 80 West. At this point,'
<br />the pipeli'ne would connect with the proposed Red Cliff Tunnel 0
<br />extending north-northeasterly 12,000 feet to a portal in the t
<br />southwest quarter of Section 15, Township 6 South, Range 80 CO
<br />West. Commencing at this portal, a 48 inch pipeline would
<br />extend 2,000 feet to the upstream portal of the DWB proposed
<br />Turkey Creek Tunnel. Diversions from the DWB proposed
<br />Roberts Tunnel Collection System including Turkey, Wearyman,
<br />and Lime Creeks would be delivered to the Turkey Creek Tunnel
<br />at this point,

<br />
<br />Turkey Creek Tunnel would extend northeasterly 32,000 feet to
<br />a point in the northwest quarter of Section 28, Township 5
<br />South, Range 79 West, and at the point would join the DWB
<br />proposed Vail Pass Tunnel. Additional DWB diversions from the
<br />Roberts Tunnel Collection System would be delivered to the Vail
<br />Pass Tunnel at this point by the connecting Gore Creek Tunnel.

<br />
<br />From the juncture of the Turkey Creek and Gore Creek Tunnels,
<br />the Vail Pass Tunnel would extend easterly 37,000 feet to its
<br />outlet portal on Ten Mile Creek near the east quarter corner of
<br />Section 33, Township 5 South, Range 78 West. From this portal,
<br />all waters would flow in Ten Mile Creek to Dillon Reservoir.

<br />
<br />Under Plan F-1, the Cities would bear the entire cost of 7,000
<br />feet of 48 inch pipeline and the Red Cliff Tunnel; also, a larger
<br />proportion of the cost for Turkey Creek and Vail Pass Tunnels
<br />than under Plan F. DWB's use of the latter two tunnels would
<br />be reduced appreciably under Plan F as its Eagle River diversions
<br />would not be transferred by this route. This plan also would be
<br />contingent upon development by the DWB of the Gore Creek
<br />Tunnel System as part of the Roberts Tunnel Collection System.
