Much of the waters of the northeastern part of the United States can be linked back to the Chesapeake Bay and its basin. For instance, the Susquehanna River of New York provides half of the freshwater found in the Chesapeake Bay, which is the country’s largest estuary. As a result, the area is rich in native flora and fauna, including these five snakes found in the Chesapeake Bay Basin.

Where Is the Chesapeake Bay Basin?
The Chesapeake Bay borders several states: Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and the District of Columbia.
However, its basin can stretch much further. A river basin is the area of land that is drained by a river and that river’s tributaries. As a result, the Chesapeake Bay’s basin includes the area surrounding its headwaters, which can be found in New York, to the area around the bay itself.
Types of Snakes Found in the Chesapeake Bay Basin
Because this is such a large area, spanning up to five hundred miles in some directions, there are countless snakes to be encountered here. Here are some of the five most common snakes in the Chesapeake Bay basin.
1. Black Rat Snake
|Scientific Name||Pantherophis obsoletus|
|Lifespan||Up to 20 years|
|Size||3 to 8 feet|
|Appearance||Black, may appear with splotches of darker colors|
The black rat snake goes by many different names. These include black snake, black chicken snake, black coluber, western rat snake, or pilot black snake. Some of these names can make it difficult to know whether or not you’re dealing with a black rat snake. In fact, both the eastern indigo snake and the eastern racer can be called the black snake. There are one subspecies of black rat snake.
Because the black rat snake is a nonvenomous snake species, it has found other ways to protect itself from predators. Typically, it will try to flee from potential predators – including humans. However, it may also shake its tail. This, paired with its appearance, can mimic rattlesnakes. It may also release a foul-smelling musk, similar to other species of snakes.
|Scientific Name||Agkistrodon contortrix|
|Lifespan||Up to 29 years|
|Size||2 to 3 feet|
|Appearance||Diamond head with copper coloration in an hourglass pattern|
The copperhead snake bites more people in America each year than any other species of snake, including those in the Chesapeake Bay basin. However, this doesn’t mean they’re outwardly aggressive to people. Instead, thanks to their copper hue, they easily blend into the fallen leaves. As a result, it can be easy to accidentally step on one of these snakes, leading to a bite out of defense.
Copperheads are one of the few reptiles out there capable of undergoing a process known as parthenogenesis. This means that females are able to fertilize eggs and thus produce offspring without the help of a male copperhead.
Although they’re considered top predators in the snake world, copperheads can actually be fairly docile unless hunting or threatened. During hibernation, they share dens with other types of snakes, such as rattlesnakes and black rat snakes.
3. Eastern Garter Snake
|Scientific Name||Thamnophis sirtalis|
|Lifespan||Up to 10 years|
|Size||18 to 26 inches|
|Appearance||Various colors with three stripes running along the body|
The eastern garter snake is one of many different species of garter snake. They’re also one of the more common snakes in the Chesapeake Bay basin. They can be seen most in the southern regions of the basin.
Although they won’t live in water directly, the easter garter snakes are never too far from it. They prefer to live in moist areas, whether it’s the forests and grasslands surrounding lakes and rivers or even in suburban areas such as in ditches and flower beds. They are nonvenomous and will prefer to flee whenever they encounter a threat, including humans.
You can find eastern garter snakes year round, including in the winter on sunny days. They have a widely diverse diet of small prey, including mammals, insects, and amphibians. Some have even been known to eat fish.
Because they are common with a thriving population, the eastern garter snake isn’t protected in most areas. However, they are protected throughout the entirety of the state of Georgia.
4. Eastern Kingsnake
|Scientific Name||Lampropeltis getula|
|Lifespan||Up to 25 years|
|Size||3 to 4 feet|
|Appearance||Black with white or yellow bands|
While many other species of kingsnakes sport a red, black, and yellow pattern to mimic coral snakes, the same cannot be said for the eastern kingsnake. Instead, they have shiny black scales and thin white or yellow bands along their body. They can reach up to four feet long.
The eastern kingsnake can be found as far north as New Jersey. As a result, they’re a common snake in the Chesapeake Bay basin. They’re nonvenomous and, like all snakes, are more afraid of you than you are of them. As a result, if you happen to encounter one of these beautiful snakes while you’re out and about, don’t panic and keep your distance. The eastern kingsnake would much rather flee than try to confront you.
Like the eastern garter snake, the eastern kingsnake only lives on land. However, they prefer to live in damp areas and areas close to water.
5. Northern Water Snake
|Scientific Name||Nerodia sipedon sipedon|
|Lifespan||Up to 9 years|
|Size||2 to 5 feet|
|Appearance||Dark brown with light brown markings|
At a glance, the northern water snake resembles many species of venomous snakes, including the copperhead that is also found here. However, this is another one of the nonvenomous snakes found in the Chesapeake Bay basin. It can grow to be up to five feet long and live up to nine years in captivity.
The northern water snake is actually one of several subspecies of the common water snake. This subspecies is found in the northern regions of the United States, making it more common in the more northern areas of the basin. As a result, they may not be a common sight in the Chesapeake Bay itself.
Other Snakes in the Chesapeake Bay Basin
There is one more snake of the Chesapeake Bay basin that deserves a spot on our list — the adorable rough green snake! These little snakes can grow up to 32 inches long and have long, slim, bright green bodies covered in rough-looking scales with a creamy white belly. Rough green snakes are non-venomous and can be found in leafy trees and shrubs throughout the Chesapeake Bay basin. They prey on crickets and other insects, caterpillars, snails, spiders, and small frogs. They are the only tree-dwelling snake in the Chesapeake Bay region — and are known to jump from trees into the water to take a swim!
