- There are 1.3 million alligators inhabiting the state of Florida, based on an annual census of 50 sites across the state.
- Biologists estimate the size of an alligator in the water based on the distance between the eyes. Adult male alligators can measure up to 14 feet long and weigh around 1,000 pounds.
- Lake Okeechobee, which has a surface area measuring 730 square miles, is the largest lake in Florida, as well as the most alligator-infested lake in the state.
An 11-foot alligator caused a traffic jam just northeast of Orlando on April 27, 2022. Cars backed up as the alligator made its way across State Road 417. The Seminole County Sheriff’s Office thought the gator probably came from Lake Jesup, which has a reputation as being a very alligator-infested lake.
However, that begs the question, what is the most alligator-infested lake in Florida? What other lakes have massive 11-foot alligators? Is there a lake near you that is alligator-infested? Let’s find out!
Who Counts Alligators?
Every year the Florida Fish and Wildlife Conservation Commission works with scientists and biologists to count the number of alligators in the state. The annual alligator census is taken at 50 different sites throughout the state.
The numbers are used for a variety of purposes, first to see how the once American Alligator population is doing. 40 years ago the alligators were hunted to the point of being endangered. It is a huge success story that there are now more than 1.3 million alligators in Florida!
Today, the state issues a number of alligator hunting permits to keep their numbers in check. The data from the annual census is used to determine how many permits to issue each year.
What Other Animals Share the Same Habitat As Alligators?
Alligators are found in freshwater habitats such as swamps, marshes, and wetlands, as well as in slow-moving rivers and lakes.
They are native to the southeastern United States, specifically in the states of Florida, Georgia, Alabama, Mississippi, North and South Carolina, Louisiana, and Texas. In China, alligators are found in the Yangtze River region.
Other animals that share the same habitat as alligators include:
- Various species of fish, such as catfish, gar, and bass.
- Turtles, such as the box turtle, the mud turtle, and the red-eared slider turtle.
- Snakes, such as the cottonmouth, the water moccasin, and the diamondback rattlesnake
- Birds, such as herons, egrets, ibis, and roseate spoonbills.
- Various species of mammals, such as raccoons, otters, and muskrats.
- And many other species of insects, amphibians, and invertebrates
It is important to note that alligators are apex predators and have a significant role in maintaining the balance of the ecosystem they live in.
How Do You Count Alligators?
Alligators are counted at night. Sound like a scary job? It is! Scientists go out in airboats at night and count the red-glowing eyes of the alligators. They use the distance between the eyes to estimate the size. Any alligator over 9 feet long is considered a “bull” alligator.
Adult male alligators can get to be 14 feet long and weigh around 1,000 pounds. Remember that counts are not exact and some sources vary from year to year. An Orlando News Station posted a map of the lakes in Florida with the alligator counts. Check out this interactive map of alligator counts, including the number of Bull Alligators.
Our list includes the lakes that have more than 100 alligators in this recent count.
What Are the Most Alligator-Infested Lakes in Florida?
The following lakes ranked highest in recent alligator counts. Remember that these are exact counts of alligators and total population estimates are higher. For example, estimates of Lake Okeechobee alligator populations stretch as high as about 30,000 alligators while estimates for Lake Jessup’s population reach 13,000.
It’s also worth noting this list is a total count of alligators in different lakes. Lake Jessup’s alligator count is especially notable for how small it is. The lake has just 25 square miles of surface area, yet it contains thousands of alligators. It’s estimated to be among the densest concentration of alligators for a large lake in America, although Lake Okeechobee has more alligators thanks to its massive size (730 square miles).
#5 Lake Kissimmee
- Alligator count: 2,065
- Area of Florida: South-Central
- County: Osceola County
If you want to try to see an alligator for yourself you should visit Lake Kissimmee State Park. Remember to always keep your distance from wildlife. It is recommended to stay at least 60 feet away from alligators. Use the zoom feature on your camera to catch the best photos. Do not risk getting too close to an alligator. They can react quickly and attack with little warning if you get too close.
#4 Lake Jesup
- Alligator count: 2,414
- Area of Florida: Central
- County: Seminole County
Some estimates of alligators in Lake Jesup are as high as 13,000, so this is definitely one of the most alligator-infested lakes in Florida. It is a 16,000-acre freshwater lake along the St. John’s River. Some of the locals joke about not being able to skip a rock in the lake without hitting an alligator in the head!
#3 Lake George
- Alligator count: 2,660
- Area of Florida: Eastern
- County: Volusia County
Lake George is a shallow lake on the St. John’s River, considered the second-largest lake next to Lake Okeechobee. Alligators thrive in this lake and along the banks of the river. During the cooler winter months, you may see alligators basking in the sun along the shoreline. Because they are cold-blooded reptiles they need to regulate their temperature by adjusting to the environment.
#2 Orange Lake
- Alligator count: 2,732
- Area of Florida: Central
- County: Alachua County
Orange Lake is a 19.61 square mile lake (12,550 acres), the largest lake in north-central Florida. If you are an angler you will know that Orange Lake is a good place to catch Bluegill, crappie, sunfish, and largemouth bass. It is right next to Lake Lochloosa which has a recent count of 338 alligators. It is likely that males travel between the two lakes looking for mates during the mating season.
#1 Lake Okeechobee
- Alligator count: 9,308
- Area of Florida: South-Central
- Counties: Glades, Hendry, Martin, Okeechobee, and Palm Beach
Lake Okeechobee is the largest lake in Florida. It has a surface area of 730 square miles. Biologists performing the alligator census break the count into different regions of the lake due to the large size. This lake is not only home to most alligators it has more than 40 native fish species and a variety of birds like egrets, herons, and ibises.

- Honorable Mention: Alligator Lake: 47, central, Osceola County: Although Alligator Lake did not have more than 100 alligators in the recent count, they have to be mentioned for their namesake alone. It is a semi-rural lake so it is not as touristy as GatorWorld for sure. People live on Alligator Lake! I am not a realtor, but that would be a hard sell for me. You could book a room at the Lakeside Inn and Café in St. Cloud, Florida if you feel like spending some time in an alligator-infested lake in Florida!
How Long Do Alligators Live?
The typical alligator can live between 30 and 50 years. Some of these ancient animals can live close to 80 years, though this is often the animals in captivity. The oldest living alligator lives in the Belgrade Zoo in Serbia and is supposed to be over 85 years old!
Alligators are often safe from predators except for humans and occasionally other alligators. Humans do a lot of damage to alligators, from hunting to habitat loss and contamination from pesticides and fertilizers that cause an alligator’s demise.
Interestingly, alligators have no finite life span. This is called negligible senescence or coined “biologically immortal.” These organisms do not exhibit the signs of biological aging; they just continue to grow in size. However, they obviously don’t live forever. If they didn’t experience disease, accidents, or rarely another large predator that sped along their death, a lack of food is another large reason. They might have a harder time hunting, lose teeth along the way, or the area does not offer the resources they need, so the alligators pass away from starvation.
