Example of releases following recommendations that would achieve recommended target flows in Reach 2. Actual releases would be determined on the basis
of specific conditions and needs identified in a given year.
Flows recorded at the USGS gage near Greendale, Utah.
Flows modeled from gauged inflows to Flaming Gorge Reservoir and Yampa River flows.
Flows that would result from example Flaming Gorge recommended releases and Yampa River inflows.
Flow measured at the USGS gage near Jensen, Utah.
Flows modeled from gauged inflows to Flaming Gorge Reservoir and inflows from Green River tributaries.
Flows that would result from Flaming Gorge releases and tributary inflows.
Flows measured at the USGS gage near Green River, Utah.
Hydrologic conditions as defined in text; exceedance values are based on actual April to July inflow into Flaming Gorge Reservoir. Years were chosen to be
representative of a particular hydrologic condition.
