(c) Len~th of re~ayment ?eriod will de?end on the final
irrigation cost allocation, but will not exceed 50 years. There
will be no development period.

(d) Each district will pay its pro rata share of the annual
cost to the United States for the operation, maintenance, and
replacement costs of Narrows Dam and Reservoir allocated to irrigation.
LSPWCD's share will be B7.~37 percent (104,400 A.F./119,400 A.F.),
and CCWCD's share will be 12,563 percent (15,000 A.F./119,400 A.F.).

(e) Water will be delivered and measured at the outlet works
of Narrows Dam and Reservoir with the districts being responsible
for losses and the delivery of water beyond that point.

(f) In the event Narrows Reservoir water is converted from
irrigation use to municipal and industrial use in the future, each
year (1) the total cost allocated to irrigation less amounts
previously paid shall be suballocated between Irrigation and M&I
based on the pro rata share of the project water supply used in that
year for each pumose, (2) the annual repayment installment cited
in (a) above shall be adjusted to reflect repayment of the M&I
suballocation within the remaining years of the repayment period
and (3) interest, computed at the rate determined in accordance with
the Narrows Unit authorization act, on the then remaining unpaid costs
suballocated to M&I use shall be paid to the United States.

(g) The excess land limitations of federal Reclamation Law will
not apply to district lands which as of August 2B, 1970 (date of
Narrows Unit authorizing act), had an existing water supply and
for which project water provides a supplemental supply. for all
other district lands, the excess land limitations shall apply.

House Document 320 contemplated that a contract between the owners
or Jackson Lake and the United States would specify a service charge
to be paid by the former of $10,000 annually. This service charge
cited in House Document 320, is based on savings to the owners in
annual operation, maintenance, and replacement costs estimated to be
$16,000 annually that would result from the purchase of Jackson Lake
by the United States and providing replacement service to the present
owners or Jackson Lake from Narrows Dam and Reservoir. The $10,000
annual service charge would be applied to the repayment of the irriga-
tion construction allocation and would be in addition to the $525,000
annual payment made by the Lower South Platte Water Conservancy District
and the Central Colorado Water Conservancy District. Prior to contract
negotiations with the Jackson Lake interests, the O&M savin~s and the
?ro~osed service charge, cited in House Document 320, will be reevaluated
based on current cost levels.

At the time that the Unit was authorized, it was estimated that the
