throughout the surrmer may not exceed 150 ft3 /s. The Operat i ng Plan
is to maintain the reservoir as near as possible to elevation 7764 feet
(2 feet below the spillway cres t) unt i 1 i't is necessary to draw the
reservoir down for downstream demands or for storage space for the
following spring runoff. The Colorado, Division of Wildlife has
requested that the minimum outflow be maintained at or above 100 ft3/s
from September 1 through November 15 to e.nhance the downstream brown
trout spawning. These flows can be maintained under normal conditions.

If water is sold to entities downstream, the outflow from the reservoir
will be adjusted to the situation at the time of delivery and will be
included in the overall operation.

Table 13 and exhibit 21 show the anti~ipated operation of Ruedi
Reservoir during water year 1989.

C. West Slope Collection System

In water year 1989, the Hunter system portion of the West Slope
Collection System will be in operation to divert approximately
7,000 acre-feet of water. Of this, up to :3,000 acre-feet will be used
for the Twin Lakes Reservoir and Canal C~mpany exchange. Diversions
from the Fryi ngpan River Bas i n are ,antic i pated to be around
35,000 acre-feet during this water year. 'The present plan will allow
for the drawdown at Twi n Lakes for the removal of the two dikes and
construction of a bypass channel around the old outlet works. The work
is presently Scheduled to be begin October 1, 1989. The exchange of up
to 3,000 acre-feet of water into the Roari ng Fork River with the
Company I s system will be made agai n th i s year. Under the terms of the
exchange the water is to be furn i shed toi the Company at Twi n Lakes.
This exchange will be done through and by; means of Project diversions
and storage in exchange for the Company ma~ing equivalent releases from
the headwaters of the Roaring Fork River. i The Company's releases would
otherwise be diverted through their collection and diversion system.
The exchange wi 11 be operated according to water year 1989 criteria
'during the period October 1, 1988, through September 30, 1989 (appendix
B) .

D. Turquoise Lake

Inflow to Turquoise Lake for water ,year 1989 wi 11 be from four
sources: Busk-Ivanhoe imports, Fryingp~n-Arkansas Project imports,
Homestake Project imports, and native flaw of Lake Fork. Estimates of
inflow from Busk-Ivanhoe and native Lake Fork were made using historical
records and probability analysis. Project water imports are estimated
to be 35,000 acre-feet. Homestake ,will import approx ima te ly
23,900 acre-feet of flow-through water for Otero pumping plant. The
City of Colorado Springs \~i 11 refill its allocated space by use of
native exchanges whereas the city of Aurdra wi 11 refi 11 its allocated
space from imports.
