Captivating narrative history of a small man-made lake in Pennsylvania. The owners and function are traced back to William Penn land grands, including information about the people who owned, created and worked the associated mill. The authors trace its ownership and function through its 150 years as a functioning mill pond, as it transformed to a summer colony for half a century, to the vibrant year round community that exists today. The influence of external events such as technology, war, political and environmental movements and their impact are traced alongside the lake's history.
