Screen the Government Canal prior to or concurrent with construction of
the fishway at the Government Highline Diversion Dam.
Retrofit the Redlands Power Canal that diverts water from the Gunnison
River with a fish screen as soon as possible to eliminate the possibility of both
sub-adult and adult Colorado pikeminnow and stocked razorback sucker that have
ascended the fishway and that have been released upstream of the dam from
moving into and perishing in canal system.
Monitor the effectiveness of screens in these canals and modify the design
and operations as needed.
Postpone any stocking or relocating of listed species upstream from
Government Highline Dam on the Upper Colorado River and Redlands Diversion
Dam on the Gunnison River until fish screens are operational.
Continue to stock domestic-reared razorback sucker harvested from grow-
out ponds in the Grand Valley downstream from diversion structures on the Upper
Colorado and Gunnison rivers until fish screens are in place in the above
mentioned canals.
Collect fish-use information at the trapping facility at the upstream end of
the fish passageway planned fro Government Highline Dam to determine use of
the fishway by Colorado pikeminnow and razorback sucker.
Radio tag Colorado pikeminnow that are collected in the fish trap of the
Government Highline fishway; monitor movement following their release
upstream of the dam, and determine the extent of upstream movement and
retention in the Upper Colorado River. Radio tagging smaller adult Colorado
pikeminnow (e.g., 450-500 mm), could provide the opportunity to further test the
hypothesis that smaller Colorado pikeminnow would remain in upstream reaches
and are better suited to establish residency than larger adult Colorado pikeminnow
(> 500 mm).
Monitor any fallback by Colorado pikeminnow over the Government
Highline Diversion Dam.
Continue to record river water temperatures at Una, Rulison Bridge, and
immediately upstream from the Rifle Bridge to establish a water database for
reaches upstream between Government Highline Diversion Dam and Rifle. These
data could also be included in the multi-year data set that are being collected over
a series of thermographs located at various sites along the Upper Colorado River
from Green River confluence upstream from Rifle, Colorado. These data are
being assembled by the Grand Junction CRFP office to develop a basin-wide
water temperature model. The model could be used to correlate water
