Response:

Article 9 of the Operating Principles, see appendix B, stipulate that
no diversions shall be made which will reduce the remaining aggregate
streamflows to less than either of the following minimum standards:

"(i) The Fryingpan collection system at the points
of diversion collectively, exclus!ve of Lillie Creek: 15 ft3/s
October 1 through March 31; 30 ft Is April 1 through
September 30.
(ii) Near Norrie (immediately below the junction of
North Fork and Fryingpan River); 30 ft3/s October 1
through March 31; 100 ft3/s April 1 through April 30;
150 ft3/s May 1 through May 31; 200 ft3/s June 1
through June 30; 100 ft3/s July 1 through July 31;
75 ftJ/s August 1 through August 31; 65 ft3/s September 1
through September 30.
In maintaining the above minimum standards, the
, Project diversions shall be regulated, so far 88 is
practicable, in such a manner that the North Fork of
the Fryingpan River, the Fryingpan River, and each of
the t,r1butaries of those streams, shall contribute to
the residual streamflows required by those minimum
standards quantities of water in proportion to their
natura.1 contributions. . ." (underline added)

In accordance with the above criteria, the Fryingpan River near Norrie
will have a minimum flow in excess of 30 ft3/s from April 1 to September
These flows will range from 65 ft3/s to 200 ft3/s. Insofar as using
excess water in the streams for oil shale development is concerned,
the Ruedi Reservoir conservation storage capacity was deeigned to
accommodate future potential uses of water in the western slope area.
In low flow periods when the natural flows are le88 than these minimum
flows, no diversions will be made.

10. Issue:
below Ruedi

The 39 ft3/s winter flow and the 110 ft3/s summer flows
Reservoir are entirely too low.
