Ruddy Duck are being observed more frequently on the refuge. The first brood was observed in 2017 at Canvasback Lake wetland complex and the second in 2018 at Shack Lake complex. These sightings are novel because they expand the breeding range for the species, representing the northwestern extent. A note describing expansion of Ruddy Duck breeding range in Alaska was published in the September issue of the journal, Western Birds. Available online at:

Alaska Native people living within and near the Yukon Flats are primarily Gwich'in Athabascans. Seven villages lie within or adjacent to the boundary of Yukon Flats National Wildlife Refuge. Local residents have a long history of harvesting the region's natural resources for subsistence purposes. Athabascans follow patterns of harvest that reflect the seasonal cycle of resources and continue to hunt, fish, trap, pick berries, and cut house logs on the refuge.

During the late 1950s, a major hydroelectric dam project was proposed for the Yukon River at Rampart Canyon, 200 miles downriver from the refuge. That dam, if constructed, would have flooded the entire Yukon Flats and the villages within it, creating a lake larger than Lake Erie. Environmental organizations, hunters, Alaska Native groups, and the U.S. Fish and Wildlife Service took a firm stand against this proposed project. In order to illustrate the importance of the Yukon Flats to national waterfowl populations, biologists conducted extensive waterfowl banding efforts. The results of these efforts showed that birds breeding on the Yukon Flats overwintered throughout the entire United States, supplementing each of the four North American flyways. The final report stated that “Nowhere in the history of water development in North America have the fish and wildlife losses anticipated to result from a single project been so overwhelming.” As a result, official protection of the Yukon Flats by the federal government began in 1978 with the designation of the Yukon Flats National Wildlife Monument.
