JUJ.l\ River Basin Recovery Program. Once said, it should be possible to eliminate the mentions of
"risks" (line 518) if Navajo were not re-operated.

Line 541 lists the San Juan-Chama Project. Are the San Juan-Chama Project depletions dependent

GQlenJl CoIJUllDll: Adaptive management is cOnuJlOn to all of the alternatives. Once an adequate
description is developed as to what adaptive management is, it should be mentioned brieflv in each
of the a1tcmatives.

Line 569. What does the Ilhra.se "to meet the statistical requirements of the spring flaw
recommendations" mean?

UIIe 572. "All releases will be made within the operational limitations/constraints of Navajo Dam."
There needs to be some explanation as to what these are, as this cannot be sunnised from this
description.

Lille 575. There is a discourse in this paragraph regarding how Reclamation will set Navajo releases.
This applies to all of thealtematives, not just the 250/S000. It needs to be stated for all of the
alternatives, and perhaps included in the "adaptive mailagement" section, as this appears to be how
adaptive management will be carried out.

LilIes 586 IUId 587. There is no way to discern the meaning of the 1" two sentences in this
paragraph regarding flexibi1ity. This is very confusing. Furthennore, the entire paragraph, i.e., lines
586 through 594, appears to apply not only to the 25015000 alternative, but to all of the alternatives.

Lille 602. This paragraph also appears to be common to all alternatives, not just the 250/5000
alternative. This panigraph appears to be yet another discussion of the adaptive management process.
It continues on in the next two paragraphs through line 619. This material needs to be extracted and
incorporated into a definitive and imellillible discussion of "adaptive management" with a statement
that adaptive management is conunon to all of the alternatives.

Line 621. The discussion in this entire paragraph is quite confusing. It is not clear how or when
minimum summer releases might be above 250 cfs.

UIIe 632. Delete "at the present time,"

Lille 642. This appears to be yet another example ofbo-w adaptive management would be applied.
It is actually common to all alternatives.

Line 68& Delete the sentence starting with "Reducing minimum releases. . ."

Line 700. How would water shortages oCGUr to other planned water projects? Why is tJ1is unique
to this alternative? The information provided in the 500/5000 alternative does not provide adequate
infonnation to compare this alternative with other alternatives.
