Supplementary Information
Waterfowl Activity: Highest numbers of waterfowl were
observed in Upper Pool 4 (60%) and Elk Reservoir (20%). At this time
these two impoundments have the greatest variety of habitats available.
Deep water to shallow flooded moist soils and cover from winds which
were gusting between 10 and 20 mph on the day of the survey.
Hunting Pressure and Success: No hunt in progress.
Weather: Local weather was warm with daytime highs between 65 and 70.
However, the refuge experienced two mornings of hard frosts. Rainfall
has been sparse since October 13th. Impoundments totally dependent on
rainfall are beginning to dry up again.
Habitat: Impoundments where the refuge is able to control the water
levels bringing the water level up slow and steady seem to be attracting
the majority of the waterfowl. One observation was made of approximately
200 Canada geese sitting in a stripped corn field at Upper Pool 4.
