It then turns east, then north, again passing under the Steese Highway and entering the Yukon Flats National Wildlife Refuge. Turning northwest, it ends where it splits into two distributaries, Lower Mouth Birch Creek and Upper Mouth Birch Creek, near Birch Creek, Alaska.

Ridgefield National Wildlife Refuge is a wildlife refuge, one of the national wildlife refuges operated by the United States Fish and Wildlife Service, located in the westernmost part of Clark County, Washington. The refuge protects more than 5,200 acres (2,100 ha) of marshes, grasslands, and woodlands. The refuge was established in 1965, in response to a need to establish vital winter habitat for wintering waterfowl with an emphasis on the dusky Canada goose whose nesting areas in Alaska were severely impacted by the violent earthquake of 1964. Ridgefield NWR is part of the Ridgefield National Wildlife Refuge Complex, headquartered in Ridgefield, Washington, which oversees the management of four refuges in the southwestern part of the state: Ridgefield, and three refuges in the Columbia River Gorge: Franz Lake, Pierce, and Steigerwald Lake. This place was closed in spring of 2019 to cut down Douglas fir and change the trail. In fall of 2020, the construction of a new multi-purpose building began. The new multi-purpose building will be a construction type V-B and consist of a 4,415 square foot single story building with an associated balcony and basement area. The building is being constructed to provide the fish and wildlife staff office space, meeting space, and an area for public visitors including volunteers and conservation partners.

Lake Mason National Wildlife Refuge is located in the center of the U.S. state of Montana. The refuge has numerous lakes and extensive marshlands along Willow Creek, which provide nesting habitat for over a hundred bird species. The refuge is managed from the Charles M. Russell National Wildlife Refuge and is normally unstaffed and has few visitor improvements. The refuge consists of three discontinuous areas; the Lake Mason area which has seasonal wetlands, the North section consisting primarily of uplands and the Willow Creek section which was set aside to protect habitat for the mountain plover.
The Yukon Delta National Wildlife Refuge is a United States National Wildlife Refuge covering about 19.16 million acres (77,500 km2) in southwestern Alaska. It is the second-largest National Wildlife Refuge in the country, only slightly smaller than the Arctic National Wildlife Refuge. It is a coastal plain extending to the Bering Sea, covering the delta created by the Yukon and Kuskokwim rivers. The delta includes extensive wetlands near sea level that are often inundated by Bering Sea tides. It is bordered on the east by Wood-Tikchik State Park, the largest state park in the United States. The refuge is administered from offices in Bethel.
The Izembek National Wildlife Refuge is the smallest of the National Wildlife Refuges located in the U.S. state of Alaska. It lies on the northwest coastal side of central Aleutians East Borough. Almost all of the refuge was designated as wilderness in 1980 under the Alaska National Interest Lands Conservation Act. The refuge is administered from offices in Cold Bay.
The Yukon Flats are a vast area of wetlands, forest, bog, and low-lying ground centered on the confluence of the Yukon River, Porcupine River, and Chandalar River in the central portion of the U.S. state of Alaska. The Yukon Flats are bordered in the north by the Brooks Range, in the south by the White Mountains, and cover an area of approximately 11,000 square miles (28,490 km2). The Yukon Flats are a critical waterfowl breeding ground due to the large area of wetland provided by the estimated 40,000 small lakes and streams in the area. In recognition of this fact, the area is protected under the Yukon Flats National Wildlife Refuge.
Kanuti National Wildlife Refuge is a national wildlife refuge in central Alaska, United States. One of 16 refuges in Alaska, it was established in 1980 when Congress passed The Alaska National Interest Lands Conservation Act (ANILCA). At 1,640,000 acres (6,600 km2), Kanuti Refuge is about the size of the state of Delaware. Located at the Arctic Circle, the refuge is a prime example of Alaska's boreal ecosystem. It is dominated by black and white spruce, with some white birch and poplars.
The Koyukuk National Wildlife Refuge is a 3,500,000-acre (14,000 km2) conservation area in Alaska. It lies within the floodplain of the Koyukuk River, in a basin that extends from the Yukon River to the Purcell Mountains and the foothills of the Brooks Range. This region of wetlands is home to fish, waterfowl, beaver and Alaskan moose, and wooded lowlands where two species of fox, bears, wolf packs, Canadian lynx and marten prowl.
Tetlin National Wildlife Refuge is a dynamic landscape made up of forests, wetlands, tundra, lakes, mountains and glacial rivers bounded by the snowy peaks of the Alaska Range. This upper Tanana River valley has been called the "Tetlin Passage," because it serves as a major migratory route for birds traveling to and from Canada, the lower 48 and both Central and South America. Many of these birds breed and nest on the refuge. Others pass through on their way to breeding and nesting grounds elsewhere in the state. Migrants, including ducks, geese, swans, cranes, raptors and songbirds, begin arriving in the valley in April, and continue into early June. An estimated 116 species breed on Tetlin during the short summer, when long days and warm temperatures accelerate the growth of plants, insects and other invertebrates, providing a ready source of rich foods for nesting birds.
Dominated by the Ahklun Mountains in the north and the cold waters of Bristol Bay to the south, Togiak National Wildlife Refuge confronts the traveler with a kaleidoscope of landscapes. The natural forces that have shaped this land range from the violent and powerful to the geologically patient. Earthquakes and volcanoes filled the former role, and their marks can still be found, but it was the gradual advance and retreat of glacial ice that carved many of the physical features of this refuge.
