The
Betsie River is a stream in the northwest part of the
U.S. state of
Michigan. The name is derived from the
French , 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.
