Au Sable River (Michigan)

Locals, including native Americans used the River for hunting, fishing and as an inland link for trapping, trading, and transiting between Lake Michigan and Lake Huron. In the late 1800's, the river transported logs downstream to sawmills and shipping yards in the towns of AuGres and Oscoda. After logging, hydroelectric dams were built during the 1920's to generate power. Today, recreation is the most popular utilization of the river.{{cite web |title=Au Sable River |url=https://www.rivers.gov/river/ausable#:~:text=Recreation&text=is%20permitt...-,It%20may%20just%20be%20the%20finest%20brown%20trout%20fly%2Dfishing,at%20some%20of%20the%20campgrounds. |website=rivers.gov |publisher=National Wife and Scenic Rivers System |access-date=24 March 2025}}

The main stream of the river is formed at {{coord|44|48|21|N|84|45|29|W|region:US-MI_type:river_source:GNIS|name=Au Sable River (source)}}{{cite gnis|1619052|Au Sable River}} in Frederic Township in Crawford County by the confluence of Kolke{{gnis|629846|Kolke Creek}} and Bradford Creeks,{{cite gnis|621843|Bradford Creek}} which both rise in Otsego County. The river flows south then turns east through Grayling, where it is joined by the East Branch Au Sable River at {{coord|44|39|55|N|84|42|13|W|region:US-MI_type:river_source:GNIS|name=East Branch Au Sable River (mouth)}}.

The Au Sable continues eastward and is joined by the South Branch Au Sable River at {{coord|44|39|23|N|84|28|06|W|region:US-MI_type:river_source:GNIS|name=South Branch Au Sable River (mouth)}} in South Branch Township.

The Au Sable then flows mostly east through Oscoda County, then south and east through Alcona County and Iosco County. The river's watershed also drains portions of Montmorency County and Ogemaw County.

Most of the main branch of the Au Sable flows through or adjacent to the Huron-Manistee National Forest. {{convert|23|mi}} of the river, from the Mio Pond downstream to the Alcona Pond, was designated as a National Wild and Scenic River on October 4, 1984. The watershed provides habitat for bald eagles and the endangered Kirtland's warbler. Five percent of the land in the watershed is National Forest and 29% is state forest.

The Grayling species of fish was once abundant in the Au Sable River, although the species has been extirpated in Michigan since 1936.{{cite web|url=http://www.michigan.gov/dnr/0,4570,7-153-10364_18958-53612--,00.html|title=Michigan Grayling Only a Memory|publisher=Michigan Department of Natural Resources}}{{cite journal |title=Fish Distributions and Habitat Associations in Manistee River, Michigan, Tributaries: Implications for Arctic Grayling Restoration |author=Goble, C.

Brook trout were released into the river in the 1880s and proved stronger than the Grayling.

There have been many attempts to bring the Grayling back to the area, but none have been successful. The city of Grayling, Michigan was named after the once plentiful fish. Brown trout is the current main catch.

Activities include paddle sports (kayaking and canoeing), fishing, primitive camping, backpacking and hiking. There are several "developed" campgrounds as well as primitive campgrounds.

It is a designated trout stream, and many canoe liveries exist along the river, which offer paddling trips from a few hours to as long as a week. Impoundments of five of the six dams on the Au Sable create lakes that are used for power boating, water skiing and sail boating.

In addition to brown, rainbow and brook trout in the river, there are perch, muskellunge and walleye, large and smallmouth bass, northern pike and bluegill in the dam ponds. Salmon and steelhead trout are popular during spring and fall spawning migrations.
