terms of the exchange the water is to be furnished to the Company at
Twin Lakes. This exchange will be done through and by means of Project
diversions and storage in exchange for the Company making equivalent
releases from the headwaters of the Roaring Fork River. The Company's
releases would otherwise be diverted through their collection and diver-
sion system. The exchange will be operated a~cording to water year 1986
criteria during the period October 1, 1986, through April 30, 1987, and
according to water year 1987 criteria the remainder of water year 1987
(appendix B).

D. Turquoise Lake

Inflow to Turquoise Lake for water year 1987 wi 11 be from four
sources: Busk-Ivanhoe imports, Fryingpan-Arkansas Project imports,
Homestake Project imports, and native flow of Lake Fork. Estimates of
inflow from Busk-Ivanhoe and native Lake Fork were made using historical
records and probabil ity analys i s. .Project water imports are estimated
to be 30,500 acre-feet. Homestake will import sufficient water to fill
their 30,000 acre-feet of storage space and have flow-through water for
Otero pumping plant.

The planned operation of Turquoise Lake for water year 1987 wi 11 be to
maintain the reservoir at or near capacity by the storage of Project
imports, Busk-Ivanhoe imports, and Homestake Project imports.

The Pueblo Board of Water Works and High Line Canal Company each own
one-half of the Busk-Ivanhoe imports. The High Line Canal Company water
wi 11 be stored in Turquoise Lake under contract unless or until their
space is not available due to Project storage demand. The Pueblo
water wi 11 either be bypassed through Turquoise Lake for storage in
Clear Creek Reservoir or for direct flow usage at Pueblo or be stored in
their long-term storage space in Turquoise Lake.

The city of Colorado Springs can store all of the native inflow to
Turquoise Lake when they are in priority (maximum of 17,416 acre-feet).

Water released from Turquoise Lake in excess of either instream minimum
flow or flow to meet downstream senior rights along Lake Fork will be
diverted into the Mt. Elbert Conduit. The water will flow through
Mt. Elbert Powerplant and then be released to the Arkansas River from
Twin Lakes via Lake Creek.

The minimum release into Lake Fork is 15 cubic feet per second, or
natural inflow, whichever is less.

Table 11 and exhibit 20 show the proposed operation of Turquoise Lake in
water year 1987.
