7. Diversion of the available Big Thompson River water and reduced or precluded
deliveries of non - charge deliveries would have enhanced the spring peak flows in the
15 -Mile Reach significantly and would have accomplished or largely accomplished the
CFOPS goals in this regard. Our analysis indicated that diversions of the available Big
Thompson River water would have increased the spring peak flows by an average of
18,498 acre -feet in the middle -range flow years, which would have nearly met the
CFOPS goal for spring peak flow enhancement of an average 20,000 acre -feet annually.
Increased diversions of the available Big Thompson River water and the elimination of
the historical non - charge deliveries would have increased the spring peak flows by an
Iaverage of 74,409 acre -feet.
