November 1993 December 1993 January 1994 February 1994 March 1994 Mean daily flows (cfs) and volumes (acre-feet) of the Green River for November, 1993 through March, 1994, as measured at Jensen, UT(USGS gage 09261000).

Mean daily flows (cfs) and volumes (acre-feet) of the Green River for November, 1993 through March, 1994, as measured at Greendale, UT (USGS gage 09234500).

Mean daily flows at Jensen varied from a high of2,959 cfs in December to 2,401 cfs in February (Table 4). Despite lower releases from Flaming Gorge Dam in March, flows at Jensen were higher from the start of spring runoff from the Yampa River. Table 4. 4.2 Flows During Winter of 1994-95 Releases from Flaming Gorge Dam in winter of 1994-95 were of a lower volume with less daily fluctuation than in the previous winter of 1993-94. In 1994-95, mean daily flows of the Green River at Greendale varied from a high of 1,305 cfs in December to 828 cfs in March, and monthly volume released varied from 80,250 acre-feet in December to 50,920 acre-feet in March (Table 5). Hourly releases from December through February varied by less than 300 cfs (Figure 2). On a daily basis, hourly releases were nearly constant (Figure 3). Hence, a relatively low volume, stable release scenario was established for winter of 1994-95. 10
