adequate capacity for the mean annual flood except in some low-lying flood plain areas. The
streamf10ws in the Roaring Fork River are typical of the natural runoff cycle of high mountain
watersheds (p. 3.5).

*The Operating Principles describe replacement capacity as that part of total reservoir capacity
required to permit project diversions when diversions could not otherwise be made because of
simultaneous demands of senior diversions in western Colorado at the time these principles
were adopted. An estimated 28,000 AF is available on a preferred basis to the extent actually
needed for replacement purposes. In 2002, 625 AF was released, the record to date for
replacement water.
**An additional 5,000 AF of water is available from Ruedi Reservoir in 4'years out of 5 through
re-regulation of the reservoir.

Operating Principles of the Fryingpan-Arkansas Project define minimum releases (hereafter referred
to as "minimum releases") from the reservoir:

For the protection of recreational values, including fishing, on the Fryingpan River below
Ruedi Reservoir, releases of water from said reservoir, not to exceed the stream inflow, shall
be made so that the streamflow immediately below the junction of the Fryingpan River and
Rocky Fork shall not be reduced below 39 cfs from November 1 to April 30, and 110 cfs
from May 1 to October 30, or as actual experience or court decree hereafter dictate (p, 4).
