2003 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.
The last flight for this season was flown on December 12, 2003.
