Objective 4. Collect data from the hydrological records for two time periods (WY
1992-1996 vs. 1997-2004) as recorded by the USGS at their near Greendale, Utah
gaging station (09234500).
Objective 5. Collect main channel temperatures in Browns Park and Lodore Canyon
in coordination with other ongoing efforts.
Objective 6. Compare and contrast the summer thermal regime of the Green River
through Browns Park and Lodore Canyon for two time periods (WY 1991 to 1996 vs.
1997 to 2003). Temperature models will be used to generate thermal regimes, where
empirical data are lacking.
Goal: Develop a program to monitor the effect of future Flaming Gorge operations on the fish
community in Lodore and Whirlpool canyons.
Objective 7. Conduct fish community sampling into Whirlpool Canyon.
Objective 8. Collect flow data in Whirlpool Canyon USGS stations at the Deerlodge
Park gage on the Yampa River, and the Greendale, Utah and Jensen, Utah gages on
the Green River.
Objective 9. Collect water temperature data in Whirlpool Canyon.
Objective 10. Based on the conclusions of these investigations (Obj. 1-9),
recommend a process to monitor future effects of operations at Flaming Gorge Dam
on the downstream fish community.
