Although Nassau County was the primary residence of Theodore Roosevelt, the name was taken by another council in Arizona.

The reservation is operated by the Theodore Roosevelt Council, BSA and is located near Wading River, New York.

The reservation comprises 400 acres (1.6 km2) of camp located in the Long Island Pine Barrens and surrounds the 30-acre (120,000 m2) "Deep Pond".

The reservation ceased being used as a summer camp in 1976, but is still often used for troop, family, district and council events.

The property on which the reservation is located has a long and rich history, which begins with the Lenni-Lenape Indians.

The Sun Trail ran from Hudson River to the East Branch of the Delaware and was so-called because an Indian or scout could start running at sunup and reach the other end by sundown.

[7][8] In 1911,[9] the Orchard Lake Club was formed by New York City businessmen who purchased the property to enjoy the trout fishing and beauty of the woods.

[10] By the turn of the century, what is now the Al Nassau area of the reservation was then a small town consisting of five houses, a logging camp and a mill for the Resherif Lumber Company.

He used it as a private retreat until 1956 when the Nassau County Council bought the property with the help of a donation from Mr. Alfred H. Capery.
