Pool 7. Pool 7 had the highest concentration on this survey. Over 500
Gadwall were observed in Pool 12 with only a few wigeon mixed in.
Hunting Pressure and Success: No hunt in progress.
Weather: Sunday Nov 10 a cold front with severe weather (high wind,
heavy
rain) moved through middle Tennessee. Temperatures for the week are
predicted to be cooler then previous week. Night time lows in mid 40's
and
day time highs in the mid 50's should be the norm.
Habitat: Rain that fell this Nov 10 - 11 has elevated the water level by
several inches in Pool 7 shallow flooding unharvested crop land. The
combination increased level, unharvested crops and additional moist
acreage
resulted in highest concentration of ducks occurring in Pool 7.
