Oneida Lake, the largest lake in New York State, which is found about 10 miles north of Syracuse, is the fifth most polluted lake in the United States, according to Discover Amazing Animals.

"Algal blooms and rooted vegetation hampered the recreational use of Oneida Lake, prompting the state to add the lake to its list of impaired waters under the Clean Water Act in 1998. Excess nutrients, particularly phosphorus, from agricultural, urban, and suburban runoff fueled algal blooms in the lake," Discover Amazing Animals states.

With a surface area of about 80 miles, Oneida Lake is the biggest lake in New York State. The lake is about 21 miles long and 5 miles wide. It flows through four New York counties: Madison, Oswego, Oneida and Onondaga counties, according to the DEC.

While researching the lake, I was pretty surprised to find "Why does Oneida Lake smell?" as the most popular question on Google. The Oneida Lake Association provided the following answer:

Odors of algae, vegetation, and fish mix together, saturating the air with a rich blending. Midges and related aquatic insects rise from the lake's depths and clouds of them hover above you while their body casings, discarded in the hatching process, punctuate the surface of the water below.

Oneida Lake is a relatively shallow natural lake with an average depth of 22 feet.

Onondaga Lake in Central New York is considered the most polluted lake in America.

"The most polluted lake in the United States is Onondaga Lake in Central New York. It’s not only one of the most polluted lakes in the country but also ranks among the most polluted lakes in the world," Discover Amazing Animals writes about Onondaga Lake. "For years, raw sewage was thrown directly into the lake, resulting in high nitrogen levels and algae blooms."

Swimming was banned in the lake in the 1940s and fishing was banned in the 1970s due to mercury contamination. Officials recently said the lake is now safe to swim in. Fishing resumed in 1986.

"Because of pollution control efforts (which began in the 1970s) and more recent cleanup work, the lake is now the cleanest it has been in over 100 years," the DEC states.

Onondaga Lake is found in Central New York, near the edge of Syracuse. The lake covers 4.6 square miles. It's about 1 mile wide and 4.6 miles long.
