Harrison Bay | John A. Patten Island Tennessee River

John A. Patten Island in Harrison Bay is a primitive, wooded retreat that seems far from civilization but is only a half an hour paddle from the busy, suburban neighborhoods of eastern Hamilton County.

The island can be accessed by canoe, kayak and SUP from launches at nearby Harrison Bay State Park.

The 100 acre island and its sister islands are all that remain of the town of Harrison, which was flooded by the Tennessee Valley Authority (TVA) when Chickamauga Lake was formed in 1940.

In addition to seeing a wide array of wildlife, visitors to the island can also see remnants of the old town, especially during the winter, when road beds and house foundations are exposed by the low lake level.
