History
Indigenous history
Indigenous people began using the river area for fishing and hunting at least 6,000 years ago. By 1600, the inhabitants were mostly
Mohicans and may have numbered 30,000.
The river's name is derived from the
Mohican phrase ''"usi-a-di-en-uk"'', translated as "beyond the mountain place" or "river of the mountain place".

"History of the Housatonic Valley."
Accessed 2015-10-1. It is referred to in the deed by which a group of twelve colonists called "The Proprietors" captured the land now called
Sherman and
New Fairfield as "Ousetonack".
Samuel Orcutt, a 19th-century historian, explained the term's pronunciation as "more properly...Howsatunnuck" and also noted an early spelling in the form of "Oweantinock".
Prior to the 18th century, the river was alternatively known as the Pootatuck River. Accounts differ on the origin of this name, with some claiming that Pootatuck is an Algonquian term translating to "river of the falls"
while others relate the term was eponymous, reflecting the name of the tribe that had their principal village along the river in the area of
Newtown, Connecticut.
"Pootatuck River" eventually came to refer a lesser tributary in the Housatonic watershed which empties into the Housatonic River at
Sandy Hook, Connecticut
Sandy Hook is a village in the town of Newtown, Connecticut, United States, founded in 1711. It was listed as a census-designated place prior to the 2020 census. According to the United States Census Bureau in 2021, it has a population of 9,1 ...

The river passes through land that was formerly occupied primarily by native people of
Algonquian lineage, typically living in villages of two to three hundred families housed in hide wigwams.
These native inhabitants burned the forests along the Housatonic Valley in the autumn to keep the underbrush down, a practice which was customary throughout Connecticut prior to European settlement.

One notable native was

Schaghticoke tribe, who still hold a portion of the former reservation on the west side of the Housatonic River, in what is now called the town of

[
English settlement of the northern Housatonic Valley began in 1725 in Sheffield, Massachusetts.] By 1734, Mohicans established the Indian Town of Stockbridge, which grew over 15 years but then failed, with land pressures increasing.
Industrialization
The river has been a source of power for paper, iron, textiles, and electricity industries. At Great Barrington, a grist mill built by David Ingersoll in 1739 used the river for power. The paper industry grew using the river's power from circa 1800.
The river was dammed with the advent of industry. In 1900, there were 30 dams on the river in Pittsfield. Many have been removed, but many remain, such as the Woods Pond dam in Lenox, Columbia Mill dam in Lee, Willow Mill dam in South Lee, Glendale dam in Stockbridge, and Rising Pond dam in Great Barrington, Massachusetts

This is estimated to be about 11,000 pounds of PCBs.][ Former filled oxbows are also polluted.]
Birds, such as ducks, and fish that live in and around the river contain significant levels of PCBs and can present health risks if consumed.
;"Rest of River" settlement agreement
Negotiations regarding how to clean up the contaminated areas south of Pittsfield had continued for many years since the initial Superfund site designations, involving GE, EPA, local governments, citizen groups and other stakeholders. In February 2020 EPA announced a settlement agreement involving GE, EPA and most of the concerned parties, to remove contaminated sediment from the river. Highly contaminated soil would be removed and shipped to federally approved facilities outside the state, while less-contaminated soil would be placed in a new specially designed landfill in Berkshire County.
Following a public comment period, EPA issued a permit in December 2020 for the final cleanup phase. In 2021 two of the citizen groups that were parties to the settlement filed an appeal of the permit, criticizing the design of the planned landfill. In February 2022 the US Environmental Appeals Board (EAB) denied the permit appeal. Following the EAB ruling, EPA has continued to design the new PCB disposal facility and has conducted public meetings in 2022. Two citizen groups appealed the EAB decision to the First Circuit Court of Appeals, and in July 2023 the court rejected the plaintiffs' challenge.
