Around the year 1910, the Delaware, Lackawanna and Western Rail Road Company was building a new section of rail known as the 'Cutoff', which lead to the creation of Lake Lackawanna.   The lake was created by a dam built by Salmon Brothers, Inc of Netcong for the Richmond Hill Investment Company. An unconfirmed rumor is that engineers were inspecting the top of the railroad fill and made comments that the valley would be an excellent place for a lake. The Richmond Hill Investment Company became involved and the purchase of the land was completed. The Civil Engineer, A. L. Colston surveyed the land and produced a development map dated 1910. The building of the dam was also completed in 1910.

In 1925, The Lake Lackawanna Investment Company, Inc. (LLIC) was formed to serve as a land development company. Over the years that followed, over 300 pieces of land were subdivided off the original LLIC property and developed as residences on Lackawanna Drive, Lake Drive, Reis Avenue, Brown Drive, Lubbers Trail, Heminover Street, Richmond Road, Carpenter Road, and Partridge Road. Unfortunately, many details of the founders and early residents have been lost to to time. We welcome any information that anyone can share.

Today, the lake is 117 acres, and there are over 300 residents who live in the community. The lake has 6 coves and 3 islands. The bigger island is named Snake Island and the smaller island is named Turtle Island, so named because of the big rock behind it that looks like a turtle with its back and head sticking out of the water.  The last island is a private island with a home on it.
