WATERFOWL SURVEYS
Upper Mississippi River NWFR Pools 4-14 and Trempealeau NWR

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 2008 waterfowl numbers by District and Pool locations.
