was determined by a gage that operated approximately 2 miles upstream of the Gunnison
River confluence during the years 1991 to 1996."
Page 25, Paragraph under Table 5: Add the words, "and shown in Table 3" at end of
the paragraph.
Page 25, last 2 sentences on page: Reword as follows, "During the July-September time
period, the CWCB's recently decreed instream flow right for 581 cfs would protect that
amount of flow in the reach from diversion by future appropriators. Also, up to an
additional 300 cfs of tributary inflow to IS-Mile Reach would be protected by the
CWCB's flow accretion right. No flows in the IS-Mile Reach are currently protected by
instream flow decrees outside the July-August-September time frame. However, the
CWCB filed in 1995 for year round instream flow rights for the IS-Mile Reach as shown
in 'Background Block 8'." We recommend moving Background Block 8 up to this point.
Page 26, Compliance with Clean Water Act, Impacts: Depending on when HUP
releases of saved water are made, there may be some impacts to water quality during the
low flow winter months. This should at least be mentioned as a possibility.
Page 28, Selenium Contamination: Need to note that lower winter flows may have
possible impacts here as well.
Page 37, Coordination with Other Recovery Program Activities, Indicator: Suggest
rewording as follows, "Progress in providing water to the IS-Mile Reach in a manner that
satisfies the U.S. Fish and Wildlife Service flow recommendations." It seems to us that
this is the goal rather than satisfaction of the CWCB's instream flows. The CWCB's
rights are to provide legal protection for these recommendations to the extent the CWCB
has determined water is both physically and legally available.
Page 37, Coordination with Other Recovery Program Activities, Existing
Conditions: Could expand a little on the Ruedi contracts, while we have actually been
delivering Ruedi water since 1988, we have only done the additional 10,000 AF contract
since 1991. Also, Coordinated Reservoir Operations were accomplished during 1997 for
the first time. The goal of Coordinated Reservoir Operations is to bypass inflows to the
major reservoirs upstream of the IS-Mile Reach during the peak of spring runoff to
increase the peak and help do additional channel maintenance work to improve habitat.
As noted, long-term agreements to deliver water from Ruedi and Wolford specifically for
endangered fish purposes are under development.
Page 37, Coordination with Other Recovery Program Activities, Existing
Conditions: Delete the paragraph on state water rights for the IS-Mile Reach if
previously discussed.
Page 37, Coordination with Other Recovery Program Activities, Existing
Conditions, Last Paragraph: Change the word, "additional" to "the remaining HUP".
We are not creating any additional conserved water, just trying to deliver the surplus that
was created as a result of the improvements.
Page 37, Background Block 8: Revise as follows, "In 1995, the Colorado Water
Conservation Board made two year-round instream flow f1lings as described below."

Base Flow Water Right - This right seeks to protect a certain defined level-of base flow in
order to limit future impacts to the endangered fish and their habitat during low.- flow'"
