The last two water sources would require transbasin diversion facilities. A smaller
reservoir decreases costs of storage, but each additional source of water results in
increased costs of feeder canals. Costs and other aspects of alternative plans are
compared in the next chapter.

Transbasin diversions from the Leroux Creek basin and from the Overland Ditch
would require the construction of the Leroux Creek feeder canal. The Leroux
Creek feeder canal could transport water from Leroux Creek, at a location just
downstream from the confluence with Cow Creek to Cactus Park reservoir. The
feeder canal would span 5.3 miles in length requiring several chutes, siphons,
flumes and other appurtenances. The capacity of the Leroux Creek feeder canal
would depend on which source of water was selected. If the source of water is
from Leroux Creek basin only, the feeder canal would require a capacity of
approximately 40 cfs, whereas, if the source of water is from Leroux Creek basin
and from the Overland Ditch, the required capacity would be approximately 80 cfs.
Diversions from the Overland Ditch system presently flow into the Cow Creek
tributary of Leroux Creek and thence to Leroux Creek. Grand Mesa project water
would be diverted from Leroux Creek into the Leroux Creek feeder canal to be
stored in Cactus Park reservoir. The present capacity of the ditch would be
increased to convey an additional 40 cfs.
