DISCUSSION
Flows
Flow volume in the Yampa River was approximately 1,000 cfs at mid-July when fish
capture and implementation began. It dropped to near 60 cfs in early September and then
rose back up to close to 400 cfs by late October, at the end of the study. The river was
flowing at less than 100 cfs for about two weeks in late August and early September.
This range of flows is typical in the decrease down to a minimum then back up to a
higher level in fall although this year's summer flows are low compared to most years.
