The lake has a lot to offer. People enjoy boating and fishing in its deep, cold waters. Its shores have small towns like Aurora and Union Springs.

Cayuga Lake is also a place for learning and culture. It's home to Cornell University and Wells College. This brings a lot of art and good food to the area, especially in Ithaca, where the motto is "Ithaca is Gorges."

Where is Cayuga Lake?

Cayuga Lake is in the middle of the Finger Lakes region in New York. It runs through Tompkins, Cayuga, and Seneca counties. Many towns border the lake, including Ithaca, Lansing, and Seneca Falls.

The city of Ithaca sits at the southern tip of the lake. It's the biggest town in the area and is known for its colleges and gorges. This is where most of the water from creeks flows into the lake.

The northern end is very different. It is a large, shallow marshland. This area is part of the Montezuma National Wildlife Refuge, which is an important spot for migrating birds.

About the Lake's Water

The lake was carved by glaciers, which is why it's so deep. This depth affects everything from its temperature to local industry.

Cayuga Lake is very deep, with a maximum depth of 435 feet. Its average depth is about 180 feet. This makes it the second deepest of the Finger Lakes.

The water in Cayuga Lake is very cold. Summer surface temperatures can feel nice, but the deep water stays around 39°F to 49°F all year.

Strong winds can cause the warm surface water and cold deep water to mix. This can make a swimming spot suddenly become dangerously cold. Cornell University actually uses this cold deep water to cool its campus buildings.

Cayuga Lake is a freshwater lake. But it has more salt than other Finger Lakes. This is because it sits on top of a huge underground salt deposit.

This salt deposit is why the Cargill Salt Mine is there. The mine operates 2,300 feet below the lake's surface. It has become a source of environmental concern.

Environmental Alert: The Cargill Salt Mine, located 2,300 feet below Cayuga Lake, poses a significant risk. A potential mine collapse could permanently contaminate the freshwater lake with salt, jeopardizing the drinking water for 100,000 people and harming the region's $3 billion tourism and agricultural economy.

People worry about the mine collapsing. A similar mine collapsed in 1994. If this mine collapsed, it could permanently fill the freshwater lake with salt.

A collapse would ruin the drinking water for 100,000 people. It would also hurt the region's $3 billion tourism and farm economy. Because of this, the state is looking into the mine's safety.

Things to Do at Cayuga Lake

Fishing on the Lake

Cayuga Lake has great fishing all year for many types of fish. Anglers come from all over to fish here. The lake is known for its coldwater and warmwater species.

Record-Breaking Catches: Cayuga Lake is famous for its trophy bass fishing. It is home to the current New York State records for both Largemouth Bass (12 lbs 6 oz, caught in 2024) and Smallmouth Bass (9 lbs, caught in 2022).

The lake is known for its huge bass. Two state records were recently caught here.

The bass are getting so big because of an invasive fish called the Round Goby. Gobies have become a huge food source for predator fish. This has helped them grow to record sizes.

Boating and Rentals

With almost 100 miles of shoreline, boating is a popular way to see the lake. There are many public boat launches and private marinas available.

Is it Safe to Swim in Cayuga Lake?

Yes, the lake is usually clean and safe for swimming. But it's a large, natural lake, so you need to be careful. The water is generally good quality and is even a source of drinking water.

About Harmful Algal Blooms (HABs)

The biggest water quality problem on the lake is Harmful Algal Blooms, or HABs. They usually appear in late summer when the weather is hot and the water is calm.

Critical Pet Safety Warning: Harmful Algal Blooms (HABs) can be lethal to dogs. The toxins can cause rapid liver failure and death, and there is no antidote. Always check water conditions before letting pets near the lake and keep them out of any water that looks suspicious. "When in doubt, stay out!"
