Harrison Bay State Park is a state park in Hamilton County, Tennessee. It sits roughly 4.1 km (2.5 mi) S of Lakesite.
Harrison Bay State Park is a 1,200-acre (4.9 km2) state demonstration park developed by the Tennessee Valley Authority in the 1930s along the shores of Chickamauga Lake. Opened in 1937, the bay gets it name from the now partially submerged town of Harrison, Tennessee. It was built at the same time as Booker T. Washington State Park. The park has a 4.2-mile (6.8-km) hiking path around the lake and has facilities including a playground, a golf course, tennis courts, a restaurant, a campground, and a marina.From the Wikipedia article “Harrison Bay State Park”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
State parks often protect a signature feature — a gorge, lake or overlook — that is best in early morning before visitors and harsh light arrive.

Milky Way & night sky
From Harrison Bay State Park, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.8 hours on a moonless night), and the core peaks around 26° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 20.03 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 47% average cloud cover) and February as the cloudiest (68%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
