Top 5 Most Snake-Infested Lakes in New Hampshire: A Guide to Coexisting with Nature

New Hampshire, a state known for its scenic beauty and abundant lakes, may not immediately come to mind when thinking of snake habitats. With cooler climates compared to southern states, New Hampshire harbors fewer species of snakes. However, the state’s lakes and rivers are home to a vital species, the Northern Water Snake (Nerodia Sipedon), which plays a crucial role in maintaining a healthy ecosystem.

Let’s explore some of New Hampshire’s most snake-populated lakes and why these snakes are nothing to fear.

Understanding New Hampshire’s Snake Population

New Hampshire is home to 11 native snake species. While some, like the garter snake, are common and found throughout the state, others, such as the timber rattlesnake, are rare and now receive state protection. Five of these species—including the timber rattlesnake, eastern hognose snake, northern black racer, smooth green snake, and ribbon snake—were identified as high-priority for conservation in New Hampshire’s 2005 Wildlife Action Plan.

Despite their presence, snakes remain poorly studied, with limited information on their distribution and life history. To address this, the New Hampshire Fish & Game Department runs the Reptile and Amphibian Reporting Program (RAARP), where sightings can be reported after proper species identification. To help with this, the department has compiled detailed information and photographs for all native snakes in the state.

Unlike southern states like Texas or Florida, where reptiles thrive in warmer temperatures, New Hampshire has a modest snake population, with only 11 species found within its borders. Among these, the only venomous snake is the Timber Rattlesnake, which is known for its mild disposition and rarity in biting humans. The more commonly encountered snake in New Hampshire’s lakes and rivers is the Northern Water Snake. These non-venomous species ( Source) thrive in semi-aquatic environments and contribute to the ecosystem by controlling pests and invasive species. (Source: WideLife.nh.gov)

1. Squam Lake: A Tranquil Habitat for Snakes and Wildlife

Location: Central New Hampshire, Lakes Region

Wildlife: Bald eagles, great blue herons, loons, lake trout

Squam Lake, known for its serenity, is the second-largest lake in New Hampshire. This peaceful fishing spot is home to a variety of wildlife, including the Northern Water Snake. These snakes are often seen along the water’s edge, hunting frogs, small fish, and occasionally birds. Visitors to Squam Lake can enjoy the beauty of the lake while knowing that the presence of water snakes is a sign of a healthy, balanced ecosystem.

Nearby, West Rattlesnake Mountain offers hiking opportunities, and while the Timber Rattlesnake has been spotted in the area, it poses little threat to humans due to its reclusive nature.

2. Lake Winnipesaukee: New Hampshire’s Largest Snake Habitat

Location: Central New Hampshire

Wildlife: Moose, birds, fish, reptiles

Lake Winnipesaukee, the largest and most popular lake in New Hampshire, is a prime habitat for the Northern Water Snake. With over 260 islands and an abundance of natural resources, the lake is an ideal hunting ground for these snakes. Tourists and locals alike may spot these snakes moving between islands, preying on small mammals, birds, and insects. Although Lake Winnipesaukee is bustling with human activity, the snakes here contribute to maintaining a balanced ecosystem.

3. Ossipee Lake: A Snake Haven with Minimal Human Interference

Location: Northeast of Lake Winnipesaukee

Recreation: Camping, fishing, hiking

Ossipee Lake’s relatively undisturbed environment makes it a perfect habitat for the Northern Water Snake. With few towns along its shores, the lake offers snakes a safe hunting ground. The snakes are often spotted along the shores, basking in the sun or swimming in search of prey. The lack of urban development around Ossipee Lake allows these snakes to thrive with minimal disruption from human activity.

4. Massabesic Lake: Where Snakes and City Life Coexist

Location: Eastern Manchester, New Hampshire

Activities: Kayaking, sailing, hiking (swimming prohibited)

Massabesic Lake, despite being close to Manchester, is home to a healthy population of Northern Water Snakes. The lake provides drinking water for the city, and while swimming is prohibited, visitors can enjoy kayaking, hiking, and sailing along its shores. These snakes are an essential part of the ecosystem, helping to control the population of small fish, amphibians, and other prey species. Their presence is a clear indicator of the lake’s ecological health.

5. Piscataqua River and Great Bay: A Unique Estuarine Habitat

Location: Portsmouth and Newmarket, New Hampshire

Wildlife: Eastern hognose snake, aquatic birds, fish

The Piscataqua River flows into the Great Bay Estuary, creating a mix of saltwater and freshwater habitats that are home to the Eastern Hognose Snake. Although venomous, the Eastern Hognose’s venom is harmless to humans, and they primarily prey on amphibians. In this region, Northern Water Snakes have been observed along the western shores of the estuary, contributing to the rich biodiversity of the area.

Why Snakes Are a Sign of a Thriving Ecosystem

While snakes may evoke fear for some, their presence in New Hampshire’s lakes is a positive sign for the environment. Predatory snakes, especially the Northern Water Snake, play a crucial role in controlling invasive species and maintaining the balance of native ecosystems. The term “infestation” may sound alarming, but these snakes are not a danger to humans and are vital for the health of New Hampshire’s waterways.

How to Safely Observe Snakes in New Hampshire

For those interested in spotting snakes in the wild, it’s important to follow a few safety tips:

• Keep a safe distance: While Northern Water Snakes are non-venomous, it’s best to observe them from afar.
• Don’t provoke: Like most wildlife, snakes will only act defensively if they feel threatened.
• Respect their habitat: Avoid disrupting the natural environment, as snakes are vital to the health of local ecosystems.
