Cancelled US dam project on Delaware River gave rise to national recreation area

A planned dam project on the Delaware River was scrapped after facing significant opposition. The cancellation was driven by environmental concerns and mounting financial costs associated with the project. Around 600 families were displaced from land that had been acquired in anticipation of the reservoir. Following the project's abandonment, the area was repurposed and eventually became the Delaware Water Gap National Recreation Area. The episode is regarded as a landmark moment in American conservation and land protection history.
