FLAMING GORGE SCOPE OF WORK 1988
Study Title: Hydraulic Study-Peaking Operation of Flaming Gorge
Study Objective: Determine the downstream stage/flow effects of
Flaming Gorge power releases, including limit of measurable
(meaningful) effect.
Relationship of Study to Flaming Gorge Operation: Flaming Gorge
is operated to produce peaking power, which creates wide
fluctuations in flow during the day creating problems for the
endangered fish which inhabit the Green River. Researchers
believe that fluctuation flows dewater backwaters, and cause some
temperature fluctuations, which may be significant to endangered
fish.
Proposed Methods: Existing field data will be analyzed, flow and
stage relationships will be developed for existing and
discontinued gages, and new field data will be gathered as
appropriate. The Bureau of Reclamation has hydraulic routing
models SSARR that will be used to translate flows from Flaming
Gorge Reservoir downstream to critical reaches on an hourly basis.
The Service will work with the-Bureau in gathering data and
calibrating the SSARR model for use in the Flaming Gorge
Biological Opinion.
FY-88 Work Plan
1. Set up and calibrate SSARR with the data derived from the
continuous flow recorders. Sites to be added are Mitten Park
in Dinosaur National Monument, Ouray National Wildlife Refuge,
and on the Green River above Willow Creek.
2. Collect additional stage discharge relationships at each of
the three continuous stream flow recording stations installed
in 1987. Develop rating tables for each of the stage
recorders and provide information for input into to the SSARR
model.
3. Participate with the Bureau in operational test of different
Flaming Gorge releases. The Service will provide people in
the field to maintain gaging equipment and to measure flow and
stage at each of our gaging locations.
4. The Service will work with.the Geological Survey to install a
data transmission platform on the gage located at Deerlodge
Park on the Yampa River. The Service will enter into a
memorandum of agreement with the Survey and the Park Service
for the maintenance of the telemetry equipment and data will
be made available through the weather service facilities.
