Alternative I-A
Two Forks Reservoir

The Two Forks Reservoir was origin-
ally proposed to store transbasin
imporls from the Blue River system
through the Harold D. Roberts Tun-
nel, in addition to Soutb Plalte River
Basin flows. The reservoir operations
and monetary impacls analyzed in
this assessment assume only storage
of native South Platte River flows,

.-

I~TII

Alternative I-e
Chatfield Reservoir

Chatfield Reservoir could not provide
conservation storage for municipal
water unless the flood control pur-
poses for which it is currently oper-
ated were foregone in whole or in
part. It would take an act of Congress
to change Chalfield's authorized pur-
poses. If the purposes were changed.
the United States' investment would
presumably become repayable in full
with interest under the provisions of
the Water Supply Act of 1958.

Alternative II-A

Grey Mountain Reservoir

for purposes of Ihis assessment.
Grey Mountain Reservoir was as-
sumed to store only presently un-
developed water not to re-regulate
already developed flows.

Alternative III-E
Trans-County

No information was available regard-
ing possible reuse of recharged water
in the Repuhlican River Basin; hence,
no water reuse benefits were cal-
culated in the analysis of this alter-
native.
