Betsie River

The Betsie River ( ) is a 54.0 mi river in the U.S. state of Michigan. The river is located in the northwestern Lower Peninsula of the state, flowing into Lake Michigan at Frankfort. The river's course is mostly within Benzie County, (which takes its name from a variant pronunciation of the river), although the river rises in western Grand Traverse County and flows briefly through northern Manistee County.

The river widens to form Betsie Lake before emptying into Lake Michigan between Frankfort and Elberta. The Betsie River is a part of Michigan's Natural Rivers Program.

Etymology
The name is derived from the French la rivière aux Bec-scies, meaning river of sawbill ducks (bec-scie). A corruption of this pronunciation led to the name of Benzie County. Other alternate historical names include the following:


 * Aug-sig-o-sebe
 * Aux Buscies River
 * Betsey's River
 * Benzie River
 * Black Robe River
 * Gay-she-say-ing
 * Riviere du Pere Marquette
 * Sawbill Ducks River
 * Shelldrake Ducks River

Course
While most sources indicate the river rises as the outflow of Green Lake in southwestern Grand Traverse County, some consider it navigable immediately south of US-31 from Tullers Lake into Green Lake. Another tributary of the river flows directly out of northern Duck Lake and into northern Green Lake, connecting with the aforementioned Tullers Lake Outlet. Although not considered part of the Betsie River today, older maps of the area do say so. Green Lake straddles the boundary between Grant Township on the south and Green Lake Township on the north between Karlin and Interlochen. Several nearby lakes, including Duck Lake and its tributaries, drain into Green Lake.

The river winds southwesterly from Green Lake into eastern Benzie County, and then briefly into northern Manistee County before turning northerly back into Benzie County. A dam on the river forms Homestead Pond, after which is flows mostly west and slightly north to Lake Michigan.



Drainage basin
The Betsie River drains an area of approximately 155026 acre in three counties. The drainage basin include about 93 mi of linear stream, 52 mi of which is part of the mainstream.

Dams

 * Homestead Dam 44.59667°N, -86.08°W was mostly removed in 1974 and currently acts as a lamprey barrier. It impounds little water and does not impede salmon migrations. The remains of the dam are now sometimes called "Homestead Falls". The dam was a power generating facility formerly owned by Consumers Energy.
 * Grass Lake Dam, approximately 4 mi downstream from Green Lake, forms an approximately 90 acre impoundment. The dam was constructed in 1951 to improve waterfowl habitat and northern pike fishing. The dam was installed by the state Wildlife Division and created a 482 acre waterfowl flooding.
 * Thompsonville Dam was an old power dam that failed in the spring of 1989 and was subsequently removed. Prior to its removal, the dam posed a barrier to salmon migration. Salmon and trout have access to the entire mainstream of the river, even above the Grass Lake Dam.
