Kettletown State Park is the public shoreline on Lake Zoar, and for the second summer in a row most of it is closed. The state's own park page, updated August 17, 2026, opens with a warning box about the August 2024 flood, and everything a buyer on the Southbury side of the lake needs to know about the park this year is in that box and the rules below it. Here it is, quoted as printed, with what each line means for someone buying near Georges Hill Road rather than camping there.
Every figure and rule below is from the Connecticut State Parks page for the park. Where this site has already quoted the state's Lake Zoar launch entry or written about the lake for a second home, the post that did so is linked.
The closure, in the state's words
The warning box reads: "Please be aware that the park sustained flood damages as a result of the unprecedented heavy rainfall event in August 2024. The campground and surrounding areas, including the Pomeraug, Crest and Brook Trails are closed, and will remain closed for the 2026 season. A reopening date has not yet been determined. The day-use areas, including the Miller Trail as well as the youth group campsites, are open per scheduled park hours." Lower on the page the campground listing still carries the line "2025 Season: Closed due to flood damage."
Two things follow. The park's lakeside campground has now missed two seasons, and the state has not set a date for a third. And the phrase the state chose, "unprecedented heavy rainfall event," is worth carrying into any conversation about a Lake Zoar shoreline property: the same storm that took out a state campground reached private shoreline too, and flood insurance on a lake house is not priced by flood zone anymore explains why that history matters more than a map.
The park in the state's words
The page describes "over six miles of trails traversing a range of terrain, scenic overlooks of picturesque Lake Zoar on the Housatonic River, a shaded picnic area, and a lakeside campground," and places the park "on the eastern shore of Lake Zoar, the fifth largest freshwater body in the state," at 605 acres. The address is 1400 Georges Hill Road, Southbury. Hours are "Open Daily (8:00 a.m. to Sunset)." The Know Before You Go rules are three: "An alcohol ban is in place at Kettletown State Park," buses seating 30 or more need a permit, and "No swimming allowed."
The history the state prints is the lake's history. The area was Pootatuck land, and "in 1919, their original village was submerged when the Housatonic River was dammed to produce hydroelectric power, creating Lake Zoar." The park's name comes from a local legend that early colonists traded one brass kettle for the right to hunt and fish here. That 1919 dam is the Stevenson Dam, and the reservoir it made is the third FirstLight lake this site covers in Lake Zoar for a second home.
The campground on paper
The page gives two counts, both printed here as the state prints them: the overview says the campground "offers 61 partially wooded and open sites," and the details list "55 RV/Tent Sites" plus "6 Rustic Cabins." Sites include a picnic table and fire ring; the maximum trailer or RV length is 28 feet; six people and a 14 day maximum per site; cabins are two room, with a double bed and two bunk beds, on a two night minimum, Friday and Saturday only. The campground rules repeat the park's: alcohol prohibited, no pets, swimming not allowed. Amenities are bathhouses with showers and a dumping station free for registered campers. Youth group camping has three sites for up to 60 campers each, open to qualified youth groups by advance reservation, and the warning box says those youth sites are open in 2026. Daily rates for residents and non-residents, the cabin processing fee, occupancy tax and deposit are printed on the page and change by season, so they are not repeated here.
Boating, fishing and the trails
- Boating. The park page's boating section is empty apart from its heading, and the campground and park rules say no swimming. The state's trailered launch on Lake Zoar is not at the park; it is the Southbury launch at 210 Scout Road, quoted with its 60 spaces and the Stevenson Dam distances in every state boat launch on the lakes this site covers.
- Trails. Of the named trails, the William Miller Trail, blue blazed, is the one the state says is open; the Pomeraug, Crest and Brook Trails are closed for 2026. The geology note sends you down the Miller Trail about 500 feet to "a large, lumpy brown boulder at the edge of the trail," a glacial erratic carried in from the Pomperaug Valley.
- Winter. "Ice fishing; weather dependent," which is the whole winter section, and a reminder that Lake Zoar is a river reservoir with a drawdown schedule of its own.
Pets and fees
Pets are allowed on leash in the picnic areas and on the hiking trails, and not permitted at the beach or the campground. Parking is free for Connecticut registered vehicles; out of state vehicles pay a daily fee that differs between weekdays and weekends, with a season pass option, and campsite fees are charged separately. The amounts are on the state's page.
What this means for a buyer on Lake Zoar
- The campground is not a factor in 2026, and the state has not said when it will be. Georges Hill Road carries day use traffic only this year. When the campground reopens, 61 sites and six cabins from late spring to fall come back with it; ask the seller what the road was like in a normal summer.
- No swimming at the park means no public beach on this stretch of the lake. A Lake Zoar listing's water access is whatever the deed and the FirstLight permit say, not the park next door.
- The flood is a fact about the lake, not just the park. August 2024 closed a state campground for at least two seasons. Ask for the property's history in that storm before the inspection, not after.
- The launch is in Southbury, the park is in Southbury, and the rulebook is FirstLight's.Candlewood, Lillinonah or Bantam puts Zoar's neighbors side by side.
The flood notification system below the Stevenson Dam
Checked September 4, 2026. FirstLight's June 26, 2026 water safety statement, issued with the Housatonic River Valley Stewards at the start of the summer season, adds a fact that belongs beside the park closure. In the Housatonic River Valley, the statement says, "heavy rainfall often brings high water levels and heightened river flows on the river, which can cause flooding in low-lying areas, particularly in Lower Housatonic communities," and the public should "avoid the river during periods of heightened flows until river conditions return to normal." It then says: "To support the Lower Housatonic community's need to anticipate and respond to high flows that could potentially bring flooding, FirstLight launched a flood notification system for the communities downstream of the Stevenson Dam, which issues emergency notifications when flows exceed a certain threshold and flooding is possible."
The Stevenson Dam is the dam that makes Lake Zoar. A buyer on the lake is upstream of that system, not in it, but the same statement is the owner's own description of how the river behaves after rain, and the Lake Zoar Authority's chair is quoted in it calling water safety "a shared responsibility among boaters, shoreline communities and the Lake Zoar Authority." Read with the state's account of the August 2024 flood above, it is the second document this year from a public or owning body that treats high water on this reservoir as a recurring event rather than a one time one.
