The Seneca Army Depot

Known for its unique white deer population, the Seneca Army Depot used a white buck in the Army base insignia.

The Seneca Ordnance Depot was one of 4 US military munition storage facilities constructed just prior to US involvement in the second World War. In 1940, the (Franklin) Roosevelt administration was preparing for full American involvement in WWII and established 4 new military supply bases that would provide munitions to defend the country's Atlantic coast in the North East and South East and our Pacific coast in the North West and South West areas of the US. The Seneca Ordnance Depot, later renamed the Seneca Army Depot, was the US Military's primary Munitions Supply Base for the Northeastern United States for more than 50 years.

From December, 1941 through the end of the cold war in the early 1990's, the Seneca Army Depot would supply nearly all of the ammunition and military supplies that were sent across the Atlantic to support our troops in WWII, the Korean Conflict, Vietnam War, first Gulf War and every other overseas conflict prior to the announcement of the base closure in 1995. This meant everything from weapons and ammunition, bombs, missiles, grenades, jeeps, uniforms, equipment, etc., came from or through Seneca.

Workers at Seneca unload ammunition from rail cars to be stored in one of the more than 500 munition igloos until it is needed overseas.

July 20, 2020 Inactivation Ceremony

When the cold war ended in the early 1990's, the United States began to downsize their munitions stockpiles and consolidate the military's supplies into fewer Army Material Command facilities. In 1995, Seneca Army Depot was one of several such bases that found themselves on the US Military's Base Realignment and Closure (B.R.A.C.) List. The United States Army held their Inactivation Ceremony for the base at the Headquarters building on July 20, 2000, and on September 30, 2000, the Seneca Army Depot was officially closed.

By 2003, the Army had turned about 2/3 of the more than 10,000 acres of the former Depot over to the Seneca County Industrial Development Agency in hopes of finding suitable new owners of the property.  The remaining property stayed under the jurisdiction of the government while it was remediated and tested for contaminants so it could also be turned over to the County IDA in the future.

Some of the property was repurposed as a County Law Enforcement Facility, or sold to build Five Points Maximum Security Prison, a facility for troubled youth known as Kid's Peace, a housing development, fiber optics & data storage company, and several others.

In 2016, the Seneca County IDA put approximately 7,500 acres up for public bid. Part of the bid criteria included a plan for the unique wildlife at the Depot; specifically, the all white, white-tail deer. Seneca Falls business owner Earl Martin prepared and submitted the winning bid. Upon winning the bid, Mr. Martin set aside approximately 3,000 acres as a wildlife preserve which he called Deer Haven Park.

More than 500 munition storage igloos dot the landscape of the former Seneca Army Depot to this day.

Today, most of  the fences remain around the former Depot. It has been more than 20 years since the official inactivation and closing of the Seneca Army Depot and nature has begun to reclaim much of the land.
