to 3,UUU acre-feet will be used for the Twin Lakes Reservoir and Canal
Company exchange. Diversions from the Fryingpan River Basin are
anticipated to be around 36,000 acre-feet during this water year. The
exchange of up to 3,UDO acre-feet of water into the Roaring Fork River
with the Company's system wi 11 be made again this year. Under the terms
of the exchange the water is to be furnished to the company at Twin Lakes.
Thi s 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 diversion
system. The exchange will be operated according to water year 1990
criteria during the period October 1, 1989, through September 30, 1990
( append i x B).

D. Turquoise Lake

Inflow to Turquoise Lake for WY 1990 will be from four sources:
Busk-Ivanhoe imports; Fryingpan-Arkansas. Project imports; Homestake
Project imports; and native flow of ~ake Fork. Estimates of inflow
from Busk-Ivanhoe and native Lake Fork' were made using historical
records and probabil ity ana lysis. Project water imports are est imated
to be 36,000 acre-feet. Homestake Project does not plan to import any
water stored in Homestake Reservoir unless the runoff is above normal.
The City of Co 1 orado Spr i ngs wi 11 refi 11 its allocated space by use of
native exchanges whereas the city of Aurora will refi 11 its allocated
space from imports.

The Pueblo Board of Water Works and the City of Aurora each own one-half
of the Busk-Ivanhoe imports. The Board's water will either be bypassed
through Turquoise Lake for storage in Clear Creek Reservoir (by exchange
with native water) or for direct flow usage at Pueblo or be stored in
their long-term storage space in Turquois(j! Lake. The City of Aurora
water will be stored in their long-term storage space.

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; ft3/s, or natural inflow,
whichever is less.
