The river has a rich history, dating back to the 18th century when it was used for logging and milling. It is also known for its role in the Battle of Plattsburgh during the War of 1812. The river is fed by several smaller streams and has a significant hydroelectric potential. There are several dams on the river, including the Rainbow Falls Dam, the Flume Falls Dam, and the Ausable Chasm Dam. These dams provide hydroelectric power and help regulate the river's flow. The Ausable River is also a popular destination for recreational activities such as fishing, kayaking, and hiking. In addition, the river supports local agriculture, including apple orchards and dairy farms.
