About this map

Bear River National Migratory Bird Refuge dominates this coastal landscape where the river meets the Great Salt Lake. The complex hydrology of the delta is documented through features like the Old Channel, Blodgetts Overflow, and Bens Overflow, reflecting the managed water systems necessary for this vital avian habitat. In the northern reaches of the Bear River Bay, human presence is marked by the Refuge Headquarters, a Landing Strip, and the Duckville Gun Club.

The map reveals a shifting environment of expansive mud flats and shallow bays, including North Bay and South Bay. Local topographical markers such as Mushback Point, Rock Island, and Pintail Neck provide orientation within the marshy terrain. The presence of the Willard Spur and various dikes like Dike Lake illustrate the 20th-century efforts to stabilize and protect this delicate ecological intersection of fresh and salt water.
