America’s lakes with the largest published alligator numbers are concentrated in Florida, led by Lake Okeechobee in a 2023 Florida Fish and Wildlife Conservation Commission (FWC) survey. That survey counted 24,678 alligators at Okeechobee, 15,404 at Lake Kissimmee, 11,881 at Lake Jesup and 11,544 at Orange Lake. These are Florida survey figures—not a definitive ranking of every American lake. “Alligator-infested” is informal shorthand for high reported abundance, not a measurement of danger. The counts also come from a particular survey period and method, so they should not be read as real-time totals.
Which lakes have the highest reported alligator counts?
The strongest lake-level figures available for this article are Florida-specific. In figures from an FWC survey conducted from May through August 2023, as reported by WKMG News 6, Lake Okeechobee had the largest reported count, followed by Lake Kissimmee, Lake Jesup and Orange Lake.

| Lake | Figure | Measure and year | Evidence note | Checked |
|---|---|---|---|---|
| Lake Okeechobee, Florida | 24,678 alligators | FWC survey count, 2023 | Largest figure in the cited survey report | November 2026 |
| Lake Kissimmee, Florida | 15,404 alligators | FWC survey count, 2023 | Second-highest figure in the cited survey report | November 2026 |
| Lake Jesup, Florida | 11,881 alligators | FWC survey count, 2023 | Third-highest figure in the cited survey report | November 2026 |
| Orange Lake, Florida | 11,544 alligators | FWC survey count, 2023 | Fourth-highest figure in the cited survey report | November 2026 |
| Lake Tohopekaliga, Florida | 5,716 alligators | Modeled population estimate, 2024 | Different year and method from the survey counts | November 2026 |
| Lake Hatchineha, Florida | 3,524 alligators | Modeled population estimate, 2024 | Different year and method from the survey counts | November 2026 |
The first four rows are one comparable set because they use the same reported 2023 survey source. The Tohopekaliga and Hatchineha figures come from the South Florida Water Management District’s 2026 South Florida Environmental Report, which describes modeled estimates for 2024. They provide useful current context, but they are not interchangeable with the 2023 night-survey counts.
Is Lake Okeechobee really America’s most alligator-filled lake?
Lake Okeechobee is the leading lake in the Florida survey figures cited here, with 24,678 alligators counted in 2023. The evidence does not establish that it is definitively number one among every lake in the United States, because no standardized, lake-by-lake national census was located.

Okeechobee is Florida’s largest lake, covering about 730 square miles, according to the FWC’s Lake Okeechobee management page. Its enormous area and extensive marsh and shoreline habitat help explain why a large count is plausible, but area alone does not produce a reliable population estimate. Counts depend on water conditions, survey coverage, visibility and the method used.
The 24,678 figure refers to the May–August 2023 survey period. It is not a live total, a guaranteed number of alligators currently present, or a count of every animal that uses the connected waterways around the lake. Treat it as a dated survey result.

Lake Kissimmee ranked second in the cited 2023 FWC survey, with 15,404 alligators. A separate official estimate shows why dates and methods matter: the 2026 South Florida Environmental Report gives a modeled 2024 population estimate of 16,186 for Lake Kissimmee.
Those two numbers do not mean the population rose by 782 animals. One is a 2023 survey count reported by a news outlet; the other is a 2024 model estimate. FWC explains that its monitoring models use night-light survey data and environmental variables such as water level and temperature, and that analyses have been revised over time. A modeled estimate can account for animals that a particular survey does not detect, while a raw count reflects what observers recorded under specific conditions.
Use the 15,404 and 16,186 figures as separate data points, always labeled by year and method. Combining them into a single trend would imply precision the underlying evidence does not support.

What do the Lake Jesup and Orange Lake numbers show?
The same 2023 survey figures place Lake Jesup at 11,881 alligators and Orange Lake at 11,544. Their close totals illustrate why a ranking needs a stated source: a different survey year, coverage boundary or analytical model could change the order.

Both lakes are in Florida’s alligator range and contain wetland habitat where alligators naturally occur. A high count says that many animals were detected or estimated in that lake system; it does not indicate that every shoreline has the same density or that visitors face a uniform level of risk.
What other Florida lake estimates are available?
The 2026 South Florida Environmental Report also lists a 2024 modeled estimate of 5,716 alligators for Lake Tohopekaliga and 3,524 for Lake Hatchineha. These values broaden the picture beyond the four lakes in the 2023 survey report, but they should remain in a separate category because they are model outputs from a different year.
Florida’s monitoring program covers about 140 alligator management units annually. A management unit may include a lake and connected waters rather than matching a simple shoreline boundary. Before comparing any two figures, check whether the geography is a named lake, a connected waterway or a larger management unit.
Why isn’t there a definitive ranking of all American lakes?
There is no single national dataset using one method, one year and one geographic definition for every lake occupied by American alligators. The current official lake-level evidence assembled here is Florida-focused, so a nationwide “top lakes” list would overstate what the data can prove.

The U.S. Fish and Wildlife Service describes the American alligator’s range as the Southeast, extending from the Carolinas to Texas and north to Arkansas. Lakes in those states may support substantial populations, but comparable, current lake-specific figures were not provided in the sources used here. Absence from this table does not mean absence of alligators; it means a directly comparable number was not available.
A 2023 ClickOrlando article relayed an older list attributed to A-Z Animals that placed Lake Okeechobee, Orange Lake, Lake George, Lake Jesup and Lake Kissimmee in its first five places. That list can help explain why readers encounter different rankings online, but it is not a current nationwide authority and should not replace dated FWC or water-management data.
What does “alligator-infested” actually mean?
In headlines, “infested” is informal shorthand for a place associated with many alligators. It is not a scientific category, and it does not mean a lake is inherently unsafe or that an attack is likely.
Alligators are native wetland predators. Their presence in a lake is expected across much of the Southeast, not a sign that a water body has suddenly become abnormal. Population abundance and personal danger are separate questions: a lake can have a large estimated population without a visitor encountering one, while a smaller population can still include an individual near a busy shoreline.
Does a high alligator count mean a higher attack risk?
No. A population estimate measures abundance; it does not calculate the probability of an encounter or attack. Risk depends on behavior, location, time of day, food availability, swimming practices, pets and whether people approach or feed animals.

FWC Alligator Management Program Coordinator Matthew Nichols summarized the practical approach in a June 24, 2025 agency release: “Because alligators can be found in nearly any waterbody in Florida, it’s safest to always assume they’re present.” That advice applies even when a lake is not on a high-count list.
How can visitors stay safe around these lakes?
FWC’s guidance is straightforward: keep your distance, keep pets away from the water’s edge, swim only in designated areas during daylight and never feed an alligator. Alligators are most active between dusk and dawn, so avoid entering or wading in natural water at those times.
- Choose a designated swimming area. Do not swim from an isolated shoreline, canal bank or boat ramp. Follow posted closures and local park instructions.
- Keep people and pets back from the edge. A dog investigating vegetation can attract an alligator; hold pets on a short leash and do not let them drink from or approach the water.
- Stay out between dusk and dawn. Low light makes animals harder to see and coincides with their peak activity.
- Never feed an alligator. Feeding is illegal in Florida and can teach an alligator to associate people with food, creating a dangerous habituated animal.
- Do not approach for a photograph. Use a trail, boardwalk or boat position that leaves a wide buffer. Compact binoculars can help with wildlife viewing from a distance, but they do not make an approach safe.
- Report a problem animal. If an alligator is unusually bold, repeatedly approaching people or occupying a recreation area, contact the appropriate Florida wildlife authorities rather than trying to move it yourself.
These precautions are behavior-based, not rank-based. They are appropriate at a small neighborhood pond as well as at Lake Okeechobee.

How should you compare alligator numbers from different sources?
Use five checks before deciding that one lake has more alligators than another:
- Metric: Is the number a raw night-light survey count or a modeled population estimate?
- Date: What year was the survey conducted or the estimate generated? The article publication date may be later.
- Coverage: Does the figure cover a named lake, connected waterways or a management unit?
- Geography: Are both locations in a dataset designed for the same state or region, or are you mixing a Florida survey with an unsystematic national list?
- Context: Does the source discuss population abundance, visitor use or safety incidents? Those are different measures.
Applying those checks explains the apparent contradiction between Lake Kissimmee’s 15,404 survey count and its 16,186 modeled estimate. They are not competing answers to the same question; they answer different questions with different inputs.

What should you take away from the current evidence?
Lake Okeechobee has the largest reported figure in the 2023 FWC survey set, followed by Lake Kissimmee, Lake Jesup and Orange Lake. Separate 2024 modeled estimates add Lake Tohopekaliga and Lake Hatchineha to the current Florida picture. None of these figures is a real-time census, and none supports a definitive ranking of every American lake.
The practical conclusion is simpler than the rankings: assume alligators may be present in suitable water across the Southeast, keep people and pets away from the edge, swim only where designated in daylight and never feed wildlife. The numbers are useful for understanding habitat and monitoring; they are not a substitute for cautious behavior.

Are alligators found outside Florida’s lakes?
Yes. The U.S. Fish and Wildlife Service places the American alligator’s range across the Southeast, from the Carolinas to Texas and north to Arkansas. The Florida figures are the best-documented lake-level numbers in this evidence set, not proof that other states lack large lake populations.
Can I use a lake’s alligator count to choose a safer vacation spot?
No. Counts describe abundance, not visitor risk. Check local park rules, designated swimming areas, recent advisories and time-of-day restrictions instead of treating a lower number as a safety guarantee.
Why do online lists put Orange Lake ahead of Lake Kissimmee?
Different lists use different years, sources and methods. The 2023 FWC figures reported by WKMG put Kissimmee above Orange Lake, while an older ClickOrlando article relaying an A-Z Animals ranking used another ordering; neither should be read as a standardized national census.
Are alligators active all year in Florida?
Activity changes with conditions, but FWC specifically warns that alligators are most active from dusk through dawn. Daylight does not make an undesignated swimming area safe, so follow posted rules and keep your distance at any time.
