Water would be <br />pumped from Harper Lake into the Louisville Lateral, which terminates approxi- <br />mately 4200 feet northeast of Harper Lake at Louisville Reservoir. In addition <br />to providing winter storage, other advantages of utilizing Harper Lake in <br />the domestic raw water supply system would include: (1) it would allow the <br />City the flexibility to maintain the storage level in Louisville Reservoir <br />when the Community Ditch and Eldorado Springs pipeline are not available for <br />use, by transferring raw water from Harper Lake to Louisville Reservoir as <br />required, (2) it would provide a storage facility to capture any City water <br />spilled from Marshall Lake under the terms of the City/FRICO Agreement dated <br />November 15, 1978, (3) it would allow the City to optimize the transfer of its <br />direct flow rights to storage in those years when incremental storage is not <br />available in Marshall Lake, and (4) it would provide storage for operation of <br />the treatment plant in the event that Louisville Reservoir is eventually drained <br />for rehabilitation. <br />The total cost of the project based on a January 1984 bid date and project <br /> <br />x <br />
