Lake Musconetcong (329 acres​​)

Lake Musconetcong

We start this list of the biggest lakes in New Jersey with Lake Musconetcong. Lake Musconetcong is like that cool, off-the-radar spot that locals might not brag about too loudly for fear it’ll get overrun with out-of-towners. Sitting pretty at 329 acres, this lake straddles the border of Morris and Sussex counties and is a stone’s throw away from Hopatcong State Park. Originally crafted in the mid-19th century as the Stanhope Reservoir, Lake Musconetcong served as an additional water source for the Morris Canal – a waterway that was the GPS of its time for transporting coal and other goods.

Over time, as the canal fell out of use, the lake shifted from industrial MVP to recreational VIP. These days, Lake Musconetcong is where you go to drop a line and hope for a fishy nibble, paddle around in a kayak, or just chill on the shore. In the winter, when it’s colder than a polar bear’s toenails, ice fishing aficionados take to the frozen waters.

Green Pond (465 acres)

Don’t let the name ‘pond’ fool you; New Jersey’s Green Pond is a 465-acre spring-fed glacial treasure that is more a lake than it is a pond. Located in Morris County, this lake has glacial origins and spring-fed sources which contribute to some of the clearest waters you could find in this part of the country.

Interestingly, the lake used to be an iron mining hotbed in the 19th century, however, those days are long gone and today, it’s one of the most beautiful relaxation spots in New Jersey. In the summer, the lake also offers a lot of water activities and fishing (mainly for trout and bass).

Now, it’s a favorite for anglers dreaming of the big catch, sailors looking for that perfect gust, and paddlers wanting serene waters with a side of scenic views.

Swartswood Lake (520 acres)

Union Lake new jersey

Union Lake, a substantial 898-acre man-made reservoir, is snuggled in the southern part of New Jersey, specifically in the town of Millville. However, despite being man-made, it’s still one of the biggest lakes in New Jersey. Dating back to the 1790s, when it was just a tiny reservoir created by damming the Maurice River, Union Lake has evolved into a significant aquatic feature after 1868, when the Millville Manufacturing Company built a new dam, beefing up its size considerably.

Lake Tappan (1,255 acres​​)

Each day, it dutifully releases up to 13 million gallons downstream to the Oradell Reservoir, a neighbor that lies entirely within Bergen County. Located at a modest elevation of 56 feet, Lake Tappan is a recreational hotspot, where the locals and visitors alike can indulge in a bit of fishing or boating.

Greenwood Lake (1,920 acres​​​​)

Greenwood Lake

Greenwood Lake straddles the border of New York and New Jersey, laying in the Town of Warwick, New York (Orange County), and West Milford, New Jersey (Passaic County). It’s a lake with quite the backstory, originally known as “Quampium” by the Munsee Native Americans and later renamed “Long Pond” by European settlers in the 18th century, who were drawn to the area for farming and ironmaking.

The lake we see today is the result of several modifications over the years. Around 1765, Peter Hasenclever of The American Company dammed the lake to enlarge it for water power used at the Long Pond Ironworks. Then, in 1837, it underwent another transformation when the Morris Canal & Banking Company built a new dam at its current location to supply water to the Morris Canal. This expansion not only increased the lake’s size but also created new geographical features like the East Arm and Chapel Island.

Lake Hopatcong (2,500 acres​​)

Lake Hopatcong

Last but not least, we round up this list of the biggest lakes in New Jersey with the largest lake around- Lake Hopatcong. Lake Hopatcong is a true gem nestled in the state’s northern highlands region. Covering about 4 square miles, this lake is a significant landmark, straddling the border between Sussex and Morris counties. Initially, it was created by damming and flooding two smaller ponds, the Great Pond and Little Pond, along with the Musconetcong River, which serves as its natural outlet.

Back in the day, Lake Hopatcong was a buzzing resort destination, drawing vacationing New Yorkers who sought a respite from the city’s hustle and today, it’s transformed into a predominantly suburban residential area, but its allure still remains…
