Gatun Lake (Lago Gatún) is one of the world's most remarkable artificial lakes, spanning 166 square miles in the heart of Panama. Created in 1913 by damming the Chagres River, Gatun Lake Panama forms the centerpiece of the iconic Panama Canal, carrying massive ships 21 miles across the Isthmus of Panama.
At 85 feet above sea level, this engineering marvel was once the largest man-made lake in the world. Today, it serves as both a crucial component of global maritime commerce and an extraordinary destination for eco-tourism, fishing, and wildlife observation.
The creation of Gatun Lake represents one of humanity's greatest engineering achievements. When American engineers took over the Panama Canal project in 1904, they made a revolutionary decision: instead of digging a sea-level canal like the French had attempted, they would create a massive lake in the middle of Panama.
The Gatun Dam, completed in 1912, was the largest earthwork dam in the world at the time. By flooding the Chagres River valley, engineers created a shortcut that eliminated the need to excavate through miles of difficult terrain. The lake reduced the canal construction by over 40 miles of digging.
When Gatun Lake was completed in 1913, it claimed the title of the world's largest artificial lake - a record it held for decades. This wasn't just about size; the lake represented a completely new approach to canal engineering. Previous canal projects had attempted to cut channels at sea level, but the Americans realized they could use the natural topography of Panama to their advantage.
The lake's unique design allowed ships to be lifted to 85 feet above sea level, then carried across the continental divide, before being lowered back to sea level. This "lake in the sky" concept was so innovative that it influenced major engineering projects worldwide.
The filling of Gatun Lake was as impressive as its construction. Once the Gatun Dam was completed in 1912, engineers simply closed the spillway gates and let nature do much of the work. The Chagres River, along with its tributaries like the Pequeñà and Trinidad rivers, began backing up behind the massive earthwork dam.
The lake filled gradually over six months, reaching its operational level by mid-1913. As the waters rose, they covered approximately 164 square miles of tropical rainforest, creating the vast inland sea that exists today. The original plan called for the lake to operate within a 5-foot range between 82 and 87 feet above sea level, and this system continues to function over a century later.
When the Chagres River was dammed, entire villages and vast tropical forests disappeared beneath the waters. The hilltops that once rose from the jungle floor became the islands you see scattered across Gatun Lake today. Occasionally, visitors can still spot the ghostly remains of submerged trees rising from the lake's depths - silent witnesses to the forest that once covered this land [6].
The flooding created something unexpected: one of Central America's most important wildlife refuges. The newly formed islands became perfect habitats for animals displaced by the rising waters. Over the past century, Gatun Lake Panama has evolved into a biodiversity hotspot where rainforest wildlife thrives just minutes from one of the world's busiest shipping lanes.
Gatun Lake is home to an extraordinary variety of wildlife, making it one of Panama's premier destinations for animal observation. The lake's numerous islands serve as protected habitats where animals live undisturbed by human development.
Monkey Species You'll Encounter:
The tropical rainforest surrounding Gatun Lake Panama hosts over 400 bird species, making it a world-class birding destination:
The lake and surrounding rainforest teem with life:
American crocodiles are commonly present throughout Gatun Lake, particularly in shallow shoreline areas [3]. The Smithsonian Tropical Research Institute advises: "Stay out of the water and you should be fine" [1]. Crocodile sightings are regular features of wildlife tours, but visitors should always observe from boats and follow guide instructions.
Gatun Lake has earned international recognition as one of the world's premier peacock bass fishing destinations. These spectacular fish, introduced in the 1950s, have thrived in the lake's warm, nutrient-rich waters.

Swimming is officially prohibited throughout Gatun Lake by the Panama Canal Authority and Smithsonian Tropical Research Institute due to multiple safety hazards including American crocodiles, heavy ship traffic, and water quality concerns [1]. No designated swimming areas exist anywhere in the lake system.
Gatun Lake remains one of the world's largest artificial lakes by surface area, though it no longer holds the top spot it claimed for decades after 1913. Today's largest artificial lakes include massive reservoirs like Lake Kariba (Africa), Lake Bratsk (Russia), and Lake Nasser (Egypt), but Gatun Lake Panama maintains its historical importance as the first truly large-scale artificial lake created for navigation.
What sets Gatun Lake apart from other large artificial lakes is its unique dual purpose: it simultaneously serves as a crucial shipping waterway and a pristine wildlife sanctuary. While other artificial lakes were created primarily for hydroelectric power or water storage, Gatun Lake was designed as a functional part of a transportation system - making it one of the most actively used large artificial lakes in the world.
The lake's maximum depth of 85 feet might seem modest compared to some deeper artificial lakes, but this depth was precisely calculated for optimal ship navigation. The relatively shallow depth also contributes to the lake's warm water temperatures year-round, creating ideal conditions for the diverse fish populations that make it a world-renowned fishing destination.
