About Geist Reservoir
Geist Reservoir was built by the Indianapolis Water Company, damming Fall Creek northeast of downtown Indianapolis in 1943 to secure the growing city's drinking supply, a project that flooded the small settlement of Germantown and forced its residents to relocate. The reservoir covers about 1,900 acres across Marion, Hamilton and Hancock counties and is mostly shallow, only about 10 feet deep outside the 48-foot hole near the dam. Once purely a utility lake, it now carries heavy residential development along its shore in the Fishers and Indianapolis suburbs, along with water skiing and fishing traffic.
