Harrison Bay

Harrison Bay State Park holds the distinction of being Tennessee's first state park, established in 1937 as a Tennessee Valley Authority recreation demonstration area during the construction of Chickamauga Dam on the Tennessee River near Chattanooga. The 1,200-acre park encompasses approximately 40 miles of shoreline on Chickamauga Lake in Hamilton County, offering extensive water-based recreation just 25 minutes from downtown Chattanooga. The park was developed by the Civilian Conservation Corps, and several original CCC structures remain in use today as tangible reminders of the Depression-era work relief program that built much of Tennessee's park infrastructure. Beneath the waters of Chickamauga Lake lies the submerged town of Harrison and the last Cherokee campground in the area, villages ruled by Chief Joe Vann that were displaced during the removal era. Today the park features one of the most complete marina facilities on any TVA lake, a Jack Nicklaus-designed Bear Trace golf course, and extensive camping and trail opportunities along the scenic lakeshore.

Harrison Bay State Park's combination of lakeside forest, open meadows, and 40 miles of shoreline creates diverse habitat supporting a rich variety of wildlife adapted to both aquatic and terrestrial environments. Chickamauga Lake supports excellent fisheries for largemouth and smallmouth bass, crappie, sauger, catfish, and various sunfish species, making the park a premier fishing destination in the Chattanooga region. Great blue herons, great egrets, and osprey are common along the shoreline, and bald eagles have become regular residents of the lake as populations have recovered across the Tennessee Valley. Canada geese, mallards, and other waterfowl congregate in the bay during fall and winter migration, and the park's coves and inlets provide important wintering habitat for diving ducks. White-tailed deer are abundant in the park's forested areas, and wild turkeys, raccoons, and gray squirrels are regularly observed. The park's mature trees support nesting populations of various woodpecker species, and the shoreline attracts migrating shorebirds during spring and fall when water levels expose mudflats and sandbars. The lake's fish populations support a thriving community of piscivorous birds and mammals including belted kingfishers, mink, and river otters.

Harrison Bay State Park's vegetation reflects the Ridge and Valley physiographic province of East Tennessee, with the park's forests dominated by mixed hardwoods including white oak, red oak, tulip poplar, hickory, and sweetgum growing on the rolling terrain above the lake shoreline. Eastern red cedar is common on the drier, thinner soils near the lakeshore, and Virginia pine occurs on exposed slopes and ridgeline positions. The shoreline transition zone supports water-tolerant species including black willow, silver maple, and river birch that can withstand periodic inundation during high water periods on the managed reservoir. Understory plants include dogwood, redbud, and sassafras, with spring wildflowers including trillium, bloodroot, and violets appearing on the forest floor in March and April. The park's open meadow areas are maintained for recreational use but also support native grasses and wildflowers that provide nectar and habitat for butterflies and other pollinators. The fluctuating water levels of the managed reservoir create a dynamic shoreline environment where pioneer species colonize exposed mud during drawdowns and are submerged during high water, creating a continually changing vegetation pattern along the lake's edge.

Harrison Bay State Park is located in the Ridge and Valley physiographic province of East Tennessee, where folded and faulted Paleozoic sedimentary rocks create the characteristic parallel ridges and valleys that define the regional landscape. The underlying bedrock consists primarily of Ordovician and Silurian-age limestones and shales, deposited in tropical marine environments approximately 450 to 420 million years ago and subsequently folded during the Appalachian orogeny approximately 300 million years ago. Chickamauga Lake itself occupies a broad valley eroded along the trend of softer rock formations, with the Tennessee River exploiting the weaker limestone and shale beds as it carved its course through the region. The limestone bedrock contains abundant marine fossils and produces the alkaline soils that support the park's productive forests and agricultural surroundings. Chickamauga Dam, completed in 1940, impounds the Tennessee River to create the 36,240-acre lake that extends 58.9 miles upstream, fundamentally transforming the valley's hydrology and landscape. During winter drawdowns, remnants of the submerged town of Harrison become visible, including building foundations and old roadways that provide a poignant intersection of geology, hydrology, and human history.

Harrison Bay State Park enjoys a humid subtropical climate characteristic of the Chattanooga area in the southern Tennessee Valley, with long, warm summers and relatively mild winters that extend the outdoor recreation season from early spring through late fall. Summer temperatures frequently reach the low to mid-90s Fahrenheit with high humidity, making water-based activities on Chickamauga Lake the most popular warm-weather recreation. Winters are mild with average lows in the upper 20s to low 30s, and significant snowfall is uncommon though occasional ice storms can affect the area. Annual precipitation averages approximately 52 inches, well-distributed throughout the year with spring thunderstorms contributing the highest monthly totals. Chickamauga Lake's large water mass moderates local temperatures slightly, with cooler breezes off the lake providing some relief during summer heat. The lake's water temperature reaches the upper 70s to low 80s Fahrenheit by midsummer, creating comfortable conditions for swimming and water sports. Fall foliage in the valley typically peaks in late October to early November, later than higher elevation parks, with the lakeside forests providing scenic backdrops for golf and hiking.

The Harrison Bay area has deep historical roots extending thousands of years before European contact, with the Tennessee River valley supporting dense indigenous populations throughout the Woodland and Mississippian periods. The Cherokee established significant settlements in the area, including three villages ruled by Chief Joe Vann, one of the wealthiest and most powerful Cherokee leaders, that represented the last Cherokee campground in the immediate vicinity. The Indian Removal Act of 1830 and subsequent forced relocations devastated these communities, with the Cherokee removal along the Trail of Tears in 1838 marking the end of indigenous settlement in the area. The town of Harrison developed in the 19th century as a small river community, serving as an important crossing point on the Tennessee River and playing a minor role during Civil War operations in the Chattanooga area. The Tennessee Valley Authority's construction of Chickamauga Dam in the late 1930s fundamentally transformed the landscape, deliberately flooding the town of Harrison and surrounding farmland to create the massive reservoir that would provide flood control, navigation improvement, and hydroelectric power for the region. The displacement of Harrison's residents echoed earlier Cherokee removals, creating a layered history of communities displaced by larger governmental priorities.

Harrison Bay's establishment as a TVA recreation demonstration area in 1937, concurrent with the construction of Chickamauga Dam, made it Tennessee's first state park and a pioneer in the concept of combining water resource development with public recreation. The Civilian Conservation Corps constructed the park's initial facilities, and several CCC-built structures including stone shelters and infrastructure remain in active use today, representing some of the finest examples of Depression-era craftsmanship in the Tennessee park system. The TVA reclaimed a portion of its land in 1940 and signed a new state lease for 1,235 acres, and the park opened to the public in 1942, though full development was delayed until the 1950s. The park was initially segregated, reflecting the discriminatory practices of the era, and a separate facility was operated for African American visitors until desegregation. Major enhancements came with the opening of the Bear Trace at Harrison Bay golf course in 1999, an 18-hole championship course designed by Jack Nicklaus that stretches over 7,100 yards with panoramic lake views. The marina has grown into one of the most complete facilities on any TVA lake, with comprehensive services supporting the large recreational boating community on Chickamauga Lake.

The Bear Trace at Harrison Bay, an 18-hole championship golf course designed by Jack Nicklaus, is among the park's premier attractions, offering a challenging 7,100-yard layout with scenic views of Chickamauga Lake from multiple holes. The park's marina facility is one of the most complete on any TVA lake, providing boat launching, fuel, slip rentals, boat rentals, and fishing supplies for visitors exploring the 36,000-acre Chickamauga Lake. Several miles of hiking and biking trails wind through the park's forests and along the lakeshore, including a paved multi-use path suitable for walkers, joggers, and cyclists. The park's 40 miles of shoreline provide extensive bank fishing opportunities, and the lake's excellent bass, crappie, and catfish populations draw anglers year-round. Swimming is available at designated beach areas during summer months, and picnic pavilions and group shelters accommodate family reunions and community gatherings. During winter low-water periods, paddlers can observe remnants of the submerged town of Harrison, including building foundations and old road infrastructure visible beneath the shallow water. The park hosts seasonal events and tournaments, including fishing derbies and golf outings, throughout the year.

Harrison Bay State Park is located off Highway 58 in Harrison, Tennessee, approximately 25 minutes northeast of downtown Chattanooga, making it one of the most accessible lakeside parks in the region. The park features a large campground with 128 sites offering water and electric hookups, modern bathhouses, and a dump station for RV travelers. A group camp facility accommodates organized groups and retreats. The park does not offer cabins or lodge accommodations, but its proximity to Chattanooga provides abundant lodging options minutes from the park entrance. Day-use facilities include multiple picnic pavilions, group shelters, playgrounds, and a swimming beach with seasonal lifeguard service. The golf course pro shop offers equipment rentals, lessons, and a snack bar. The marina provides comprehensive boating services including fuel, pump-out facilities, slip rentals, and boat repairs. The park is easily accessible from Interstate 75 via Highway 58, and its location near Chattanooga's attractions including the Tennessee Aquarium, Lookout Mountain, and Chickamauga Battlefield makes it a convenient base for visitors exploring the greater Chattanooga area.

Harrison Bay State Park plays an important role in maintaining environmental quality along the shores of Chickamauga Lake, with its 1,200 acres of protected forest and managed shoreline providing buffer zones that filter runoff and protect water quality in the heavily used reservoir. The park's forests provide critical habitat for migratory and resident birds in a region where lakeside development has eliminated much of the natural shoreline vegetation along Chickamauga Lake. Water quality monitoring in the park's coves tracks nutrient levels, sediment loads, and algae growth that can affect both recreational water quality and aquatic ecosystem health. The park manages invasive plant species including privet, Japanese honeysuckle, and kudzu that can overwhelm native vegetation and reduce habitat quality for wildlife. The submerged cultural resources of the old town of Harrison and the Cherokee campground sites require ongoing consideration in lake management decisions, balancing recreational use with preservation of historically significant submerged landscapes. The Bear Trace golf course is managed using integrated pest management practices designed to minimize chemical inputs and protect water quality in the adjacent lake, recognizing the direct hydrological connection between the course and the reservoir.
