John A. Patten Island

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

Located in Harrison Bay, 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 range of wildlife on the island, including deer, turkey, waterfowl, eagle and osprey, adventurers can also see remnants of the old town, especially when road beds and house foundations are exposed by low lake levels in winter.

The island can be accessed by canoe, kayak and SUP from launches at Harrison Bay State Park to the east and north.

WARNING: There are no trails on John A. Patten Island, so a compass is highly recommended.
