It could be one of your worst nightmares.

You’re enjoying a summer day in the water when you feel something brush past your leg. You turn, and there’s a snake.

While the chances of that scenario playing out are highly unlikely, there is a good chance the waters you enjoy playing in are also inhabited by snakes.

The danger level might not be as high as Florida’s, but it’s still something to be aware of when you go into the outdoors.

Here’s a look at the snake-infested lakes and ponds in Delaware, according to worldatlas.com.

Nanticoke River

The Nanticoke River runs 64 miles from southern Delaware to the Chesapeake Bay, winding through marshlands, forests, and farmland along the way. The habitat is perfect for the Northern watersnake. The snakes are nonvenomous, but they will defensively strike if you corner them or try to hold them.

The Brandywine

This is where you need to be very careful. The Eastern copperhead is a confirmed and documented presence, and a small group exists at Alapocas Run State Park along the water near Wilmington. The snakes won’t chase you, but if you step too close or don’t see them, they will strike. You should watch your step near log piles and rocky outcrops.

Millsboro Pond

Millsboro Pond is the home to perch, black crappie and frogs, which is the perfect food for snakes including northern water snakes, plain-bellied water snakes, queen snakes and common ribbon snakes.

The Eastern copperhead lives in southern Sussex County, which includes the pond. However, sightings are rare. It’s something to watch out for when you are at the pond.

Lums Pond

The pond, located in Lums Pond State Park, has numerous varieties of snakes. However, the inlets and small islands are perfect for northern water snakes to bask in the sun. The snakes thrive on fish and amphibians and benefit from the surrounding forest and wetlands.

One snake to watch for is the ringneck snake. It has a mild venom and its teeth have trouble puncturing human skin, but for those with venom allergies, you should treat it like any other venomous species.

Trap Pond

Trap Pond, located in Trap Pond State Park, is noted for its cypress swamp. The bald cypress trees and the tree’s root structure provide a great hiding place and basking spot for eastern garter snakes and northern water snakes.

Silver Lake

Located in Dover, Silver Lake is lined with trees and vegetation, making it a great place for snakes. The northern water snake is seen here, but eastern kingsnakes are also occasionally seen in the wooded areas of the lake.

Garrison Lake

Garrison Lake is a popular spot in Kent County for fishing and boating. The marshy areas and dense vegetation are perfect habitats for northern water snakes, eastern garter snakes and eastern rat snakes. The wetlands are attractive to snakes due to the abundance of prey and the availability of cover.

Red Mills Pond

Red Mills Pond, located near Lewes, has a rich biodiversity supporting numerous amphibians and small mammals, which attract snakes. Among the snakes you may see in and around the pond are the northern water snake, eastern ribbon snake and eastern ribbon snake.
