Silver Lake Dam : ウィキペディア英語版 | Silver Lake Dam
Silver Lake Dam is located off Silver Lake Road, just outside the village of Woodridge, New York, United States. It was built in the 1840s to regulate Sandburg Creek, which provided water to the summit of the Delaware and Hudson Canal 10 miles (16 km) to the southeast. In 2000 it was listed on the National Register of Historic Places. The body of water it created eventually became known as Silver Lake, an attraction for visitors to the many Jewish summer resorts in Woodridge and neighboring communities. In the early 21st century the village of Woodridge, which owns the dam, has been working to repair it due to a leak. ==Description==
As built, the dam is a stone structure, with large mortared slabs encasing a dry rubble interior. It is long, wide along the top and rising above the water level on the downstream side. There was a centrally located spillway wide by 2 feet (50 cm) deep. Two cast-iron waste pipes controlled by large gate valves in the top of the dam next to the spillway went through the bottom of the dam.〔
