Who insures lake and high-value homes in New Hampton, New Hampshire? Portsmouth Atlantic Insurance. We are independent, we shop more than 40 carriers, and we place homes on Pemigewasset Lake, Lake Waukewan, Lake Winona and the hills above the Pemigewasset River. This is a quiet corner of the Lakes Region with private wells, wooded lots and a hydro dam on its western edge, so a good policy here starts with rebuild cost, water exposure and how often the house is lived in.
Key facts
- New Hampton had 1,175 housing units in 2020, 227 of them vacant, according to the 2024 Pemigewasset River Corridor Management Plan; in a Lakes Region town that largely means seasonal homes.
- Pemigewasset Lake covers about 250 acres in Meredith and New Hampton (Lakes Region Planning Commission, 2008).
- Lake Waukewan covers 953 acres with 8.1 miles of shore, and New Hampton holds about 1,949 acres of its watershed (Waukewan Watershed Management Plan).
- FEMA calls the Pemigewasset River corridor one of the most flood prone areas in the state, as quoted in the 2024 corridor plan.
- For New Hampton homes we look at Andover for houses up to about $1.5 million, Hanover to $2 million, National General, Openly to $5 million, and Chubb or Cincinnati above that; each underwriter makes its own decision.
Where New Hampton’s lake houses are
New Hampton sits west of Meredith and east of the Pemigewasset River, with Bristol, Hill and Bridgewater across the water. Route 104 runs through the village toward I-93 at Exit 23, which makes the town one of the easier Lakes Region drives from Concord and points south. The town’s own description places New Hampton near the geographic center of the state, about 35 minutes north of Concord, with the Ayers Island generating station inside town lines.
The lake homes split into a few distinct groups, and carriers see each one a little differently.
Pemigewasset Lake
A 250-acre lake shared with Meredith, ringed by cottages and newer year-round houses, with wetlands along parts of its shore.
Lake Waukewan, west shore
The New Hampton side of Meredith’s drinking water lake, where state watershed rules limit septic and land use near the water.
Lake Winona
A 154-acre lake with about 3.1 miles of shore, split between New Hampton and Center Harbor, with both year-round and seasonal homes.
Hill and river lots
Larger houses on Beech Hill, near Sky Pond and on the bluffs and flats above the Pemigewasset.
A camp on Winona and a new house with a view over the Pemi valley may both be worth well over a million dollars to rebuild, but they raise different questions. The lake house is about docks, winter vacancy and water quality rules. The hillside house is about the length of the driveway, the distance to water for the fire engine and how the roof handles snow load.
Living beside a hydro dam and a busy river
The Pemigewasset forms New Hampton’s western boundary, and the Ayers Island Dam holds it back near the Bristol line. The 2024 corridor plan lists Ayers Island among three High Hazard Class dams on the river, a category for dams whose failure or mis-operation would likely cost lives. That label is about consequences, not about the dam’s condition: the same plan reports that the license issued in 1996 runs to 2036, that LS Power bought the dam in 2022, and that the former owner spent several million dollars in 2011 reinforcing it against earthquakes.
For a homeowner, the more everyday issue is how the river moves. The 2008 Bristol and New Hampton tributaries plan says the impoundment can raise or drop the river several feet within hours, depending on the season and runoff, and that the banks can be steep and very sandy. Those two facts together explain why riverbank lots need care. Water rising onto a lawn is a flood claim, while a bank that slumps away under a deck or shed is erosion, which most home and flood forms treat narrowly or exclude.
What the corridor plan says about flooding
The 2024 plan says flooding on the Pemi has followed spring runoff and ice jams but has also come at other times of year, and that the September 2011 floods from Tropical Storm Irene caused substantial erosion and property damage along the river. It also notes that all eleven towns on the river advisory committee, New Hampton included, have floodplain ordinances that meet FEMA guidelines, which is what lets property owners in those towns buy NFIP flood insurance.
The protected corridor is wide. State law defines it as 1,320 feet from the normal high-water mark, or out to the edge of the 100-year floodplain if that is farther. A house a quarter mile from the river can still sit inside it, so we check the map rather than guessing from the view.
Lake Waukewan and the drinking water rule
Lake Waukewan is Meredith’s main water supply, and that gives its watershed a set of rules that most Lakes Region lakes do not have. Under Env-Dw 902.24, no new septic system or privy may be built within 125 feet of the lake, and barns or pens for horses, cattle and other animals may not be kept within 200 feet of the lake or its wetlands. Existing septic systems that work may stay, but a failed one must be replaced under current state standards.
The rule also says that a change from seasonal to year-round use, or an expansion of an existing use, has to meet its requirements. That is worth knowing before you insulate and winterize a camp. After a fire, rebuilding may require a new septic design or a different footprint, and those costs are what ordinance or law coverage is meant to help pay. We ask about the age and location of the septic and whether the house has been converted, because both affect the rebuild figure.
Water levels on Waukewan change by about 12 to 15 inches a year, and the management plan says the lake is drawn down each spring for flood control. Docks, boathouses and shoreline walls take that movement plus ice every winter. Docks are often covered only up to a set limit under the home policy, so a large permanent dock or boathouse may need to be scheduled or written separately.
Pemigewasset Lake and Lake Winona
Pemigewasset Lake is the largest lake in the Bristol and New Hampton tributaries watershed, and wetlands are more common around it than in the rest of that area. Harper Brook, Dry Brook, Magoon Brook and Hoyt Brook are the named New Hampton streams in that watershed. Low lots near the inlets and outlet are the ones we watch for standing water and wet basements.
Lake Winona is smaller and more secluded. The Waukewan plan describes its shores as developed with both year-round and seasonal homes, and it notes that about half the Winona shoreline is zoned one-acre minimum in New Hampton, while the Center Harbor half is zoned at a five-acre average. Two small islands in Winona have structures on them. Island cabins are hard to insure because fire crews cannot reach them by road, so expect fewer options and closer questions.
Any lot within 250 feet of these lakes also falls under the state’s Shoreland Water Quality Protection Act, which governs tree cutting, impervious surfaces and building near the water. Like the Waukewan rule, that can raise the cost and time of a rebuild, and the rebuild figure on your policy should allow for it.
Fire, wells and winter in a rural town
Most New Hampton homes have private wells. The 2008 regional plan notes that the New Hampton Village District was working toward a larger municipal water supply, but outside the village a house relies on its own well and septic, and fire crews often bring water by tanker. Carriers look at the distance to the fire station, the nearest year-round water source and whether the driveway can take a heavy truck in March mud.
The town’s 2009 hazard mitigation plan, posted on its hazard mitigation page, rated flooding, dam failure, wildfire, blizzards, ice storms and nor’easters among the moderate risks for New Hampton. In practice, the claims we see in towns like this come from ice dams, frozen pipes after an outage, tree limbs on roofs and water in basements. A standby generator, a remote temperature sensor and an automatic water shutoff valve are the upgrades that underwriters notice most on a seasonal house.
Our guide to snow and ice damage covers roof loads and ice dams in more detail.
Second homes and rentals
Seasonal use runs deep here. The corridor plan counts 235 vacant units in New Hampton in 2010 and 227 in 2020, while occupied homes rose from 848 to 948, which suggests some camps became year-round homes over the decade. Whether yours is lived in all year or closed for the winter changes the policy. Many forms limit coverage after a house has been unoccupied for a set stretch, and some require proof of regular checks or heat.
Short-term rentals add another layer. Tell us how many weeks you rent and whether guests use boats, rafts or a dock. Our second-home insurance page explains vacancy wording, and an umbrella policy is often the simplest way to raise liability limits for a lake house with guests.
Carriers we compare for New Hampton homes
A Waukewan cottage or an older farmhouse valued up to about $1.5 million often suits Andover. Hanover takes New Hampshire homes to $2 million, and we quote National General alongside both. When the rebuild figure climbs past that, Openly can go to $5 million, while Chubb or Cincinnati step in for the largest properties and for scheduled jewelry and art. Hagerty is where collector cars go. Rental use, wood stoves, island cabins and long vacancies are judged differently by each company; see our carrier selection process for how we sort that out.
Flood is quoted two ways: the federal program, written for us by Selective, and private flood from Neptune, Aon Edge, Flow Flood or Beyond Floods. Private plans can sometimes offer higher building limits or contents coverage that fits a finished lower level better. Read more on our flood insurance page.

Frequently asked questions
Is New Hampton part of the Lakes Region?
Yes. New Hampton is a Belknap County town between Meredith and Bristol, with the Pemigewasset River along its western edge and Interstate 93 crossing at Exit 23. Its lakes are smaller and quieter than Winnipesaukee: Pemigewasset Lake, which it shares with Meredith, the west side of Lake Waukewan, half of Lake Winona, and ponds such as Jackson Pond and Sky Pond. Carriers treat most homes here as rural Lakes Region houses on wells and septic.
My camp on Lake Waukewan is in New Hampton. Are there special rules?
Yes. Waukewan is the main drinking water supply for Meredith, and a state rule, Env-Dw 902.24, applies across its watershed in Ashland, Center Harbor, Holderness, Meredith and New Hampton. It bars new septic systems within 125 feet of the lake and says a change from seasonal to year-round use must meet the rule. That matters for insurance because a winterizing project can change both what you rebuild after a loss and what a carrier wants to know.
Does the Ayers Island Dam affect my homeowners policy?
Not directly, but it shapes the river you live beside. The 2024 Pemigewasset River corridor plan lists Ayers Island, on the Bristol and New Hampton line, as a High Hazard Class dam, and a 2008 regional plan says the impoundment can move the river level up or down several feet within hours. A home policy does not cover rising water from any source, so homes near the river or its backwaters should be checked for flood coverage.
Do I need flood insurance if my house is not near the Pemigewasset?
It depends on the lot. Low ground along the town’s brooks and lake inlets can take water in heavy rain, and the town’s 2009 hazard plan used a photo of Sky Pond Road after the August 2008 rains on its cover. We look up the parcel on the FEMA map and still quote flood when a house sits low, has a finished basement or relies on a single road. Options include NFIP coverage through Selective and private policies from Neptune, Flow Flood, Beyond Floods and Aon Edge.
Who writes larger lake homes in New Hampton?
Several do. Andover writes up to roughly $1.5 million here, Hanover to $2 million, and National General is in the mix too. Above those levels we turn to Openly, which goes to $5 million, and to Chubb or Cincinnati for the very largest lake houses. Whoever underwrites the file decides after looking at the house, the lot and its use.
I rent my lake house for part of the summer. Does that change anything?
Yes, and it should be raised before a quote. Many carriers limit short-term rentals or need them disclosed, and guests on a dock, raft or boat add liability. We may suggest a higher liability limit plus an umbrella, and we will tell you which carriers accept rentals at your level of use.
