What Canal allows a navigable water route from New York City to the Great Lakes and was created shortly after Blackstone River Valley?
Blackstone River Valley National Historical Park Blackstone River Valley National Historical Park is a National Park Service unit in the states of Rhode Island and Massachusetts. The park was created for the purpose of preserving, protecting, and interpreting the industrial heritage of the Blackstone River Valley and the urban, rural, and agricultural landscape of that region. The Blackstone River Valley was the site of some of the earliest successful textile mills in the United States, and these mills contributed significantly to the earliest American Industrial Revolution. The subsequent construction of the Blackstone Canal, a few years after the successful completion of the Erie Canal, helped to sustain the region's industrial strength.
Tocks Island Dam controversy A 1950s proposal to construct a dam near Tocks Island across the Delaware River was met with considerable controversy and protest. Tocks Island is located in the Delaware River a short distance north from the Delaware Water Gap. In order to control damaging flooding and provide clean water to supply New York City and Philadelphia, the U.S. Army Corps of Engineers proposed building a dam. When completed, the Tocks Island Dam would have created a 37-mile (60-km) long lake between Pennsylvania and New Jersey, with depths of up to 140 feet. This lake and the land surrounding were to be organized as the Tocks Island National Recreation Area. Although the dam was never built, 72,000 acres (291 km²) of land were acquired by condemnation and eminent domain. This incited environmental protesters and embittered local residents displaced by the project's preparations when their property was condemned. After the Tocks Island Dam project was withdrawn, the lands acquired were transferred to the oversight of the National Park Service which reorganized them to establish the Delaware Water Gap National Recreation Area.
