Lake Hydra, originally known as Dutch Springs, began as a limestone quarry operated by the National Portland Cement Company starting in 1933. For decades, the site produced cement, with pumps running constantly to keep the spring-fed quarry dry. When operations ceased in the 1970s, the pumps were shut off and the quarry naturally filled with water, creating a clear, spring-fed freshwater lake over 50 acres in size and reaching depths of over 100 feet.

​

In 1980, the flooded quarry was repurposed into a scuba diving facility, becoming one of the most popular inland dive sites in the Northeast. Over the years, a wide range of underwater attractions were added—sunken vehicles, a school bus, aircraft, and training platforms—making it an ideal site for diver certification and recreational exploration.

​

After a brief threat of closure in 2021–2022 due to planned warehouse development, the site was saved through community efforts and acquired by new owners. It was rebranded as Lake Hydra and continues to operate as a premier destination for divers and dive instructors across the region.
