Upper Mississippi River
National Wildlife and Fish Refuge

1999 WATERFOWL AERIAL SURVEYS

Each week during fall migration, biologists fly the Mississippi River to count the number of waterfowl using the Refuge.

This data reflects the numbers of waterfowl surveyed. Due to survey techniques, this total number is not necessarily the total number of waterfowl in a specific pool.

Total numbers of waterfowl reflect the whole refuge of Pools 4-13, unless indicated otherwise.
