Scott Falls Dam is a dam on the West Branch Musquash River near Musquash, Saint John County, New Brunswick, Canada. The dam is part of the water-retention infrastructure of the Musquash watershed, which was developed for hydroelectric generation during the early 20th century.

History The New Brunswick Electric Power Commission developed its first hydroelectric project on the Musquash River. The dam and powerhouse were completed in the spring of 1922 at a cost of $2 million. In 1972, the Musquash hydro plant was sold to the Province of New Brunswick for water-storage purposes.

The provincial government continued to maintain and rehabilitate infrastructure throughout the Musquash watershed. In 2010–11, the Department of Natural Resources spent approximately $525,000 on the system, including studies of the remaining structures at Scott Falls. More than $15 million had been spent on rehabilitation of the watershed's infrastructure since 1999.

In 2023, Fisheries and Oceans Canada identified Scott Falls Dam as a restoration project near the Musquash Estuary Marine Protected Area that could improve habitat connectivity in the watershed.
