Carnegie Lake, stretching across parts of central New Jersey, owes its existence to an unusual encounter: a conversation between a painter and Andrew Carnegie. Built in the early 1900s for Princeton’s rowing team, the lake quickly became more than just a training site. Locals fish here, paddle, or stroll along the quiet banks. Pollution has taken its toll, but efforts to clean the water are ongoing.
