Indian Lake, Ohio, formerly known as Lewistown Reservoir, was named by European-American settlers because several tribes lived in the region and found the area to be an ideal spot for both hunting and fishing. It was originally a group of small lakes and wetlands across 640 acres of land that later was built into a reservoir to collect water for the Sidney Feeder to the Miami and Erie Canal. After railways made the canal system obsolete, Indian Lake remained.
The lake has since become a destination for boating and fishing enthusiasts. It is the host for several major fishing tournaments each year as well as weekly contests held by local bass clubs. In the winter, ice fishing and snowmobiling have become greatly popular in the area.
Indian Lake has numerous islands across the center of the lake, a large wildlife area, many inlets and bays, and boasts over 30 miles of shoreline.
