Trout Brook, known in older sources as Stone Bridge Creek, is a river that is located in Warren County, New York. The river, located in the eastern Adirondack Mountains, is a third-order tributary which flows 15.7 miles (25.3 km) southeast into the Schroon River, just south of Schroon Lake.^[1] The river has three branches, and is stocked with 1,300 yearling brook trout by the New York State Department of Environmental Conservation.^[3]

The river is most notable for running through the Natural Stone Bridge and Caves, a series of marble solutional caves which was formed by the river over the course of 14,000 years.^[4] The river briefly becomes a subterranean river around the caves, resurfacing after 200 metres (660 ft) underground.^[2]
