Top 5 The Most Snake-Infested Lakes in New Hampshire

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)
