Benton Lake National Wildlife Refuge

Benton Lake National Wildlife Refuge covering 12,383 acres (19 square miles)is located on the western edge of the northern Great Plains, 50 miles east of the Rocky Mountains and 12 miles north of Great Falls. Despite its name, Benton Lake is actually a 5,000-acre shallow wetland created by the last continental glacier thousands of years ago. Benton Lake is an oasis for water birds. During spring and fall migrations, up to 150,000 ducks, 2,500 Canada geese, 40,000 snow geese, 5,000 tundra swans, and perhaps as many as 50,000 shorebirds use the marsh. Bald eagles are commonly seen in spring and fall, while an occasional golden eagle, prairie falcon, or peregrine falcon adds a bit of drama to the scene. Other Refuge wildlife includes 28 different species of mammals such as mountain cottontail, common muskrat, American badger, striped skunk, common raccoon, long-tailed weasel, Richardson's ground squirrel, coyote, and a limited number of white-tailed deer, mule deer, and pronghorn. There are no sizable fish due to the shallowness of the marsh. The Refuge is open in the fall for upland bird and waterfowl hunting. Visitors are encouraged to follow the Prairie Marsh Wildlife Drive to see and learn about the Refuge. Facilities available for visitor use include a marsh boardwalk, a sharp-tailed grouse viewing blind, and an accessible hunting blind.

There have been 199 species of birds sighted since 1961, which includes: the loon, American white pelican, great blue heron, snowy egret, trumpeter swan, Canada geese, mallards, red-breasted Merganser, osprey, bald eagle, Cooper's hawk, golden eagle, gyrfalcon, gray partridge, ring-necked pheasant, sharp-tailed grouse, mourning dove, snowy owl, burrowing owl, nighthawk, downy woodpecker, eastern kingbird, violet-green swallow, black-capped chickadee, red-breasted nuthatch, rock wren, golden-crowned kinglet, robins, European starling, Macgillivray's warbler, song sparrow, red-winged blackbird, rosy finch, and American goldfinch.
