G.I. __
Oct 1- Nov 15 2,400 (wet) whooping crane, waterfowl Low Although flows are anricipated to be below dry flow
1,800 (normal) targets during this period, EA carry-over plus 10
1,300 (dry) percent of the SNI will be conserved for higher
priority uses later in the water year.
Nov 16 - Dec 31 1,000 fish community, bald eagle Low Projections indicate flows will be at or near dry year
1,000 targets during this period.
600
Jan 1= Jan 31 1,000 fish community, bald eagle Low Projections indicate fiows will be at or near dry year
1,000 targets during this period.
600
Feb 1- Feb 15 1,800 sandhill crane, waterfowl, fish community, Low With similar gains as in 2007 during this time period,
1,800 bald eagle projections indicate flows may be above dry targets
1,200 during this period. With gains similar to those of
2004 to 2006, flows would be at or near dry targets.
Feb 16 - March 15 3,350 Sustauung beneficial processes of the river ? Estimates indicate continued shortages to dry year
3,350 and riparian wetland systems such as ice- flow targets during this period in 2008. If conditions
2,250 scouring for channel maintenance (e.g., in- are conducive to pulse flow augmentarion and
channel vegetation removal); sediment supply; adequate planning and coordinarion has occurred,
sandbar formarion; nutrient cycling; and highest priority will be given to using the EA to
groundwater recharge to stimulate biological enhance desired river processes as described in the
acrivity in wet meadows. Principal Affected Resources sections during this time
period. Highest priority will be given to pulse flow
augmentation/crearion during the months of February,
March, or A ril.
March 16-March 22 1,800 sandhill crane, waterfowl, fish community, Low With similar gains as in 2007during this time period,
1,800 bald eagle projections indicate flows will be at or near dry year
1,200 targets.
