WATERFOWL SURVEYS
Each week during fall migration, biologists
fly the Mississippi River
to count the number of waterfowl using Pools 4 - 14 of the Refuge.
Due to survey techniques, this total
number is not necessarily the total number of waterfowl in a specific
pool.
Select
links below to view 2007 waterfowl numbers by District and Pool locations.
