The Fourth Falls, also known as Upper Falls or Gooch's Falls, are the fourth of four waterfalls in Yarmouth, Maine, United States. They are located on the Royal River, approximately 0.4 miles (0.64 km) upstream of the Third Falls. The river appealed to settlers because its 45-foot rise in close proximity to navigable water each provided potential waterpower sites. As such, the four falls were used to power 57 mills between 1674 and the mid-20th century.[1]
Gooch Island stands to the east of the falls.
