Twin Branch Dam is the tallest dam with a hydroelectric power station on the St. Joseph River in Indiana. When it was first commissioned, it was called the Hen Island Dam.[2] The name Twin Branch Dame comes the Twin Branch Creek which empties into the St. Joseph River just above the dam.[3] The prior name for the dam, "Hen Island Dam," came from an island that used to be just below the dame where a riverboat resident used the island to raise geese and chickens.[3] There were two islands, one named "Hen Island" and the other "Goose Island". Both islands were taken by the river by the 1950s.[3]
