Biohazard Cleanup Near Harrison Bluff Harrison, TN

Harrison is an unincorporated census-designated place (CDP) in Hamilton County, Tennessee, within the Chattanooga metropolitan area.

The community developed near Vann's Ferry, a Tennessee River crossing established by the prominent Cherokee trader and planter James Vann, and the settlement was known in its early days as Vann Town.

The town was named for President William Henry Harrison.

Harrison became the Hamilton County seat in 1840, and the seat moved to Chattanooga in 1870.

When the Tennessee Valley Authority completed Chickamauga Dam in 1940, much of the old town of Harrison was flooded by Chickamauga Lake, and submerged building foundations and roadbeds are still visible around Harrison Bay at low water.

Harrison Bay, the lake embayment beside the CDP, is named for the flooded town.

Harrison Bay State Park, a roughly 1,200-acre park developed by the TVA in the 1930s on the Chickamauga Lake shoreline, is described as Tennessee's first state park.

The 2020 census counted 7,902 people in Harrison, up slightly from 7,769 in 2010.

The 2020 census counted 3,132 households and 2,321 families in the CDP.

Harrison is also home to the Bear Trace golf course, a Jack Nicklaus-designed course, and the TVA's Skull Island recreation area.
