1 1 I. wou Id pump from the reservoir and discharge to a tunnel and pipeline system to be constructed jointly with the DWB. As in PIa<1 E, the reservoir would permit year-round pumping at a unIform pumping rate of 74 mgd. Under Plan F, the pumping head would average 510 feet as contrasted with 1,300 feet under Plan D and 1,400 feet under Plan E, I I I I A new electrical transmission line approximately 0.4 miles long would be required to supply electric power to the pumping station. This would connect to the relocated 115 kV transmission line presently paralleling U_ S, Highway 24. Costs for the pumping station would be divided equally between the Cities and DWB. e, A system of tunnels and pipelines extending from the pump- ing station northeasterly B8,000 feet to discharge into Ten Mile Creek tributary to the DWB Dillon Reservoir. A part of the tunnel and pipeline system would also serve the DWB Eagle-Piney and Roberts Tunnel Collection Systems. I I I Commencing at the pumping station in 6-d, a 60 inch pipeline would extend 5.000 feet to a point in the southwest quarter of Section 20, Township 6 South, Range 80 West. At this point, the pipeline would connect with the proposed Red Cliff Tunnel extending north-northeasterly 12,000 feet to a portal in the southwest quarter of Section 15, Township 6 South, Range 80 West, Commencing at this portal, a 60 inch pipeline would extend 2,000 feet to the upstream portal of the DWB proposed Turkey Creek Tunnel. Water diversions from the DWB proposed Roberts Tunnel Collection System including Turkey, Wearyman !''''llnd Lime Creeks would be delivered to the Turkey Creek Tunnel ~t this point. o Turkey Creek Tunnel would extend northeasterly 32,000 feet to a point in the northwest quarter of Section 28, Township 5 South, Range 79 West, and at this point would join the DWB proposed Vail Pass Tunnel. Additional DWB diversions from the Roberts Tunnel Collection System would be delivered to the Vail I I 1 I Pass Tunnel at this point by the connecting Gore Creek Tunnel. From th!,! juncture of the Turkey Creek and Gore Creek Tunnels, the Vail Pass Tunnel would extend easterly 37,000 feet to its outlet portal on Ten Mile Creek near the east quarter corner of Section 33, Township 5 South, Range 78 West. From this portal, all waters would flow in Ten Mile Creek to Dillon Reservoir. All costs for this tunnel and pipeline system would be prorated to the Cities and the DWB on the basis of water allocations tributary to the various portions of the system. 7. Plan F-1 - Tunl1els, Pipelines, Reservoir, and Pumping Plan F-1 is similar to Plan F, except a joint undertaking would be required between the Cities and the CRWCD for Cross Creek Tunnel and Iron Mountain Reservoir, Also a joint undertaking would be required between the Cities and the DWB for Turkey Creek and Vail Pass Tunnels. No direct relationship would exist between the CRWCD and DWB. Plan F-1 includes: v o , I a. A tunnel from Homestake Valley, beginning near the center of Section 30, Township 6 South, Range 80 West, extending northwesterly 24,000 feet, passing beneath Fall Creek and Peter- son Creek and terminating below Cross Creek Valley at elevation 9,050. Riser shafts and diversion facilities would be provided at Fall, Cross, and Peterson Creeks. The diversion point on Cross Creek would be downstream of the mouths of West and East Cross Creeks and would permit all diversion from Cross Creek to be made at one location. The Cities would bear the entire tunnel cost from Cross Creek to Fall Creek. From Fall Creek to Iron Mountain Reservoir, the CRWCD would share part of the cost as it would divert water from Fall and Peterson Creeks. The total tunnel cost would be prorated approximately 87 per cent to the Cities and 13 per cent to the CRWCD. /, r t, ;1 tl ~ b.
