3. In an effort to address concerns of decreased wadeability of the Fryingpan River when
flows exceed 250 cfs, efforts will be made to limit cumulative flows to 250 cfs or less
when consistent with the multiple Project purposes and reasonable to do so; so long
as future fishery research does not indicate that flows in excess of 250 cfs are important
for Fryingpan or Roaring Fork River fishery maintenance or enhancement.
2.1.3 No Action Alternative
Reclamation would not enter into an agreement to make 10,825 of of water available for
endangered species habitat enhancement within the 15 Mile Reach through 2012, as presented in
the PBO. If Reclamation does not enter into the proposed agreement and reverts to providing
21,650 of of Ruedi water to enhance flows in the 15 Mile Reach, it is unlikely that the east and
west slope water users would continue to provide their 10,825 af. In summary, the No Action
alternative would include the following contributions from Ruedi Reservoir:
• 5,000 of annually and 5,000 of 4 out of 5 years
• 21,650 of annually of Ruedi water to enhance flows in the 15 Mile Reach
2.1.4 Alternative A
Reclamation would enter into a Memorandum of Agreement (2012 Agreement) with the CWCB
and the Service to make 10,825 of of water available annually for release from Ruedi Reservoir
to be delivered to the 15 Mile Reach of the Colorado River through the year 2012. The water
would be available to help meet flow targets in the 15 Mile Reach any time of year, but is
expected to be used in the summer and fall, primarily during the period of July to October.
The anticipated effects of this alternative are based on the assumption that all of the water is
delivered from July to October. The Proposed Action alternative would include the following
contributions from Ruedi Reservoir:
• 5,000 of annually and 5,000 of in 4 out of 5 years
• The 2012 Agreement for 10,825 of annually as described above
2.1.5 Alternative B
This alternative responds to west slope water users' concerns regarding potential inability to
meet their commitment to provide 5,412 of of water to the 15 Mile Reach, due to extraordinary
circumstances.
Alternative B would provide for the 2012 Agreement described in the Proposed Action and allow
the west slope water users' interim commitment of 5,412 af, to be supplied from unused
contracted water or available uncontracted water within the marketable yield of Ruedi Reservoir.
The water would be made available through a one-year temporary water service contract. This
need is estimated to arise 1 out of every 10 years, or 10% of the time. In summary, Alternative B
would include the following contributions from Ruedi Reservoir:
• 5,000 of annually and 5,000 of in 4 out of 5 years
• The 2012 Agreement for 10,825 of annually as described in the Proposed Action
• 5,412 of available to meet the west slope water users' commitment an average of 1 out of
10 years (10% of the time)
