Black Canyon of the Gunnison National Park, Paragraph (I )(b,), and
2, Further, the amount of water for rSF purposes shall be limited to a maximwn of
10,000 c,f,s" or such lesser amount, that when combined with tributary inflow
occurring upstream of the Gunnison River gage located near Delta, CO does not
exceed 10,000 c,f.s, (to ensure that the rSF water right does not contribute to
flooding in the Delta area); and
3, This instream flow water right shall not be exercised in a mauner that interferes
