Betsie River

The Betsie River is a 54.0-mile-long (86.9 km) stream in the northwest part of the U.S. state of Michigan. The name is derived from the French Riviere Aux Bec Scies, meaning river of sawbill ducks (bec-scie). Other alternate names include Aug-sig-o-sebe, Aux Buscies, Betsey's River, Black Robe, Gay-she-say-ing, Riviere du Pere Marquette, Sawbill Ducks, and Shelldrake Ducks. The river is mostly within Benzie County (which takes its name from a variant pronunciation of the river), although the river rises in southwest Grand Traverse County and flows briefly through northern Manistee County, Michigan.

The river widens to form Betsie Lake before emptying into Lake Michigan at 44°37′45″N 86°14′45″W / 44.62917°N 86.24583°W / 44.62917; -86.24583 between Frankfort and Elberta. The Betsie River is a part of Michigan's Natural Rivers Program.
