Construction of this inverted V-shaped outerwork began in 1814. Traces of its shape are visible today. Surrounded by a dry ditch, the Water Battery mounted 24-pounder guns that provided an additional level of firepower to the fort.

The Water Battery underwent two major changes after 1872. The gatehouse and other buildings were removed and construction of earthworks to surround the fort began. Four platforms for 15-inch Rodman guns and three magazines were completed before the government interest and funding waned.

The Endicott System in the 1890s brought the construction of Battery White, the concrete structure that is visible now.

Ricochet Firing
Guns in the Water Battery could ricochet, or bounce, shot across the river surface and hit a ship near the waterline causing severe hull damage.
