The Mid-winter Waterfowl Survey was a nationwide effort to survey waterfowl in areas of major concentration on their wintering grounds and provide winter distribution and habitat affiliations. This survey also served as a primary source of data on population trends for some species that breed in remote Arctic locations and were difficult to survey using traditional methods. Therefore, abundance indices for some of these species were obtained from surveys on wintering areas. For species not covered in other population surveys these indices provided direct inputs into management programs such as harvest management plans.  Most of these species-specific winter surveys still exist and those time series can be found in Flyway Data Books.

The Mid-winter Waterfowl Survey was discontinued as a nationwide effort after 2015, but data were still collected through 2019 as some States transitioned out, and some continued "winter surveys" to current day (available from those States).  To obtain Mid-winter Waterfowl Survey data, please visit the Flyway's FileShare website.
