During the 1940s, the Army stored radioactive materials in connection with the
Manhattan Project in igloos E0801 through E0811, on the south end of the Depot. Despite no formal confirmation from the Department of Defense, it is known that during the cold war the depot held the largest stockpile of Army nuclear weapons in the country. The Army
RADCON team performed a survey on these igloos during the week of May 13, 1985. In 1978 the
United States Coast Guard opened a
Loran-C transmitter station on the base. It closed in 2010, made obsolete by GPS. The depot was a major employer in the region. It was linked to the outside world by the airfield,
railroad lines and highways (
NY-96 and
NY-96A). The depot was not included in any of the 1990s Base Realignment and Closure plans. After the 1995 base recommendations, the Army announced that the base would close. The Seneca County Industrial Development Agency filed suit in federal court. The lawsuit ended when the Army agreed to provide the same benefits to the community as were available to those in the formal closure process. The depot formally shut down on September 30, 2000. In August 2002, The Glen Region of the Sports Car Club of America (
SCCA) began using the airfield for
autocross racing competitions, but site availability after August 2011 is not yet determined. In early 2007, the Cornell 2007 DARPA Urban Challenge Team began using the depot's private roads to test its autonomous vehicles. Some warehouses are leased to The Advantage Group, which runs a storage and shipping business. Much of the housing at the depot has been sold to private developers and is now available as part of the area's civilian housing stock. Much of the railroad track and outer yards are being used for railroad car storage. As of 2008, no customers ship by rail. The depot's former airfield is slated for use as a
New York State Police training center. In early 2007, Cilion announced plans to build an
ethanol plant on a portion of the former depot, but the project languished and appears to have died in the face of rising costs for corn and public concern about the wisdom of the project. An article dated July 20, 2009 in the Watertown Daily Times stated that the Fort Drum-based
10th Mountain Division (Light Infantry) would soon start using the depot for combat training. A portion of the southern end of the base was transferred to New York State and used for the construction of Five Points Correctional Facility, a maximum security prison. Land also was transferred to Seneca County for the construction of a county jail and sheriff's office. == Demonstrations against nuclear weapons storage ==
