Alouette River, Brook in Pitt Meadows, Canada.

The Alouette River is a waterway in Pitt Meadows that flows westward from mountain sources toward populated areas. It joins the Pitt River and connects to the broader regional river system.

The river was officially renamed in 1914 to avoid confusion with another regional waterway that shared its previous name. This change reflects how the territory was organized by early settlers and officials.

The name Alouette, French for "lark", was chosen in 1914 because it sounds like the river's former name, Lillooet, which it replaced to avoid confusion with the larger Lillooet River. The river holds British Columbia Heritage River status.

The Alouette River leaves Alouette Lake and runs west to join the North Alouette River, then continues west to enter the Pitt River at Pitt Meadows. Part of the lake's water is diverted through a pressure tunnel to a powerhouse at nearby Stave Lake, so flows below the dam vary. The river holds British Columbia Heritage River status.

Part of the Alouette's water is diverted through a pressure tunnel to a hydroelectric plant at nearby Stave Lake, so the river below Alouette Lake carries less than its full flow. The Alouette holds the status of a British Columbia Heritage River.
