Geist Reservoir, Water reservoir in northeastern Indianapolis, United States.
The reservoir spreads across 1,890 acres through Marion, Hamilton, and Hancock counties, reaching depths of 48 feet at its maximum point.
The Indianapolis Water Company acquired 5,727 acres in the 1920s and constructed a dam across Fall Creek in 1941 to form the reservoir.
The Indianapolis Sailing Club established a presence at the reservoir, making it a center for water sports and recreational activities.
The reservoir holds 6.9 billion gallons of water and serves as a primary water source for the metropolitan area of Indianapolis.
The former town of Germantown now rests at the bottom of the reservoir, submerged during its creation in 1943.
