Culver's Lake

Culver's Lake (formerly Round Pond) is located in Frankford Township, in Sussex County, New Jersey. Fed by Lake Owassa and Bear Swamp, Culver's Lake is the source of the West Branch of the Paulins Kill (also known as the "Culver Brook"). In the late 19th and early 20th century, the lake was used for seasonal recreation. Today, it is a private year-round community owned and operated by the Normanoch Association, a homeowners' association.

The lake has a surface area of approximately 555 acres and a shoreline roughly six and a half miles long. It has a maximum depth of 50 ft and is located at an elevation of 830 ft above sea level. It is located near the Culver Gap, a wind gap in Kittatinny Mountain, and where the Appalachian Trail intersects with U.S. Route 206.

Culver Gap near Culver's Lake in Sussex County, New Jersey, was an important route through the Kittatinny Mountain from about 10,000 years ago to present. The gap is more than 400 feet (120 m) below the top of the mountain. Lenape Native Americans used the gap to hunt and trade on both sides of the mountain. Early settlers from Pennsylvania used the water drop from Culvers Lake to Branchville for a wide assortment of mills. Turnpikes followed the route of Lenape trails through the gap.

The lake is named for a local clergyman, the Reverend Jabez Collver (1731-1818), who led the Congregational Church in Wantage Township, New Jersey. On September 14, 1774, he purchased 163 acres of land east of Kittatinny Mountain near the lake. However, after the American Revolution, Collver fled to Ontario, Canada after the American Revolution due to his loyalist sympathies.
