Culver's Lake (formerly Round Pond) is located in Frankford Township, in Sussex County, New Jersey.

[1] The lake has a surface area of approximately 555 acres (225 ha) and a shoreline roughly six and a half miles long.

Early settlers from Pennsylvania used the water drop from Culvers Lake to Branchville for a wide assortment of mills.

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.
