Humans (and beavers) have been manipulating water flow for millenia, but it wasn’t until recently that we developed the materials we’d need to create enormous bodies of water. Once we did, we created some of the largest lakes and inland seas the Earth’s ever held. Here are eight of the largest man-made lakes in the world.
Williston Lake | British Columbia, Canada
70 Billion Cubic Meters
Williston Lake was formed in 1968 with the completion of W.A.C. Bennet Dam, blocking the Peace River and creating the largest body of freshwater in British Columbia. Besides being a huge source of electricity, the lake’s nice to look at. It’s bordered by the Cassiar Mountains to the west and the Rocky Mountains to the east, both being striking natural features. In fact, Williston Lake comes close to a fjord in some respects.
Krasnoyarsk Reservoir | Divnogorsk, Russia
73.3 Billion Cubic Meters
Besides its massive size (a size that’s earned it the informal name of the Krasnoyarsk Sea), the Krasnoyarsk Reservoir’s claim to fame is being the world’s largest power plant from 1971 to 1983. In 1983, it was unseated by the Grand Coulee Dam in Washington State. The reservoir and the dam also appear on the 10 ruble bill, meaning most Russians have at least seen the thing in a picture, if not in person. A final note on the dam is the fact that a substantial section of the river below it doesn’t freeze over, even though it’s in frigid Siberia. This is because the water’s moving much too fast coming out of the dam and for miles downstream.
Manicouagan Reservoir | Quebec, Canada
138 Billion Cubic Meters
The Manicouagan Reservoir is a perfect intersection of human engineering and natural phenomena. Human engineering produced the reservoir when the Daniel-Johnson Dam was built in the 1960s. The natural aspect concerns the reservoir’s unique ring shape. The shape was created by an asteroid impact roughly 214 million years ago. That means Manicouagan Reservoir is actually a flooded crater, similar to Crater Lake (except Crater Lake is far younger and a volcano). There’s a theory that the Manicouagan crater is actually part of a multiple impact event spanning modern day North America and Europe.
Guri Reservoir | Bolivar, Venezuela
138 Billion Cubic Meters
It doesn’t look like the publicity around the Guri Reservoir is entirely good. For one, apparently the Guri Dam generates more carbon emissions than the fossil fuel alternative, which is about as hard to do as you’d think. There have also been some substantial blackouts in the 21st century, and the reservoir has a tendency to fall below optimum levels for electrical production. Still, it’s a big lake, right?
Lake Volta | Ajena, Ghana
153 Billion Cubic Meters
Just like all the other lakes on this list, Lake Volta wouldn’t be around without a dam to fill it up. In this case, it’s Akosombo Dam, built between 1961 and 1965. Interesting to note about Lake Volta, before the dam was built, the Black Volta and White Volta rivers used to meet, but once the lake started filling in, that confluence was wiped away. It’s a navigable lake, which was probably part of the point of building the dam. With it, the trip from the savanna to the coast and vice versa got a lot easier.
Bratsk Reservoir | Bratsk, Russia
169 Billion Cubic Meters
As much as we hate to play into stereotypes, it seems like Russians really know how to handle the cold. The Bratsk Dam was built through Siberian winters, far away from the things needed to build it, including supplies, laborers and construction support. But they did it anyway and ended up with the Bratsk Reservoir to show for it. The reservoir is on the Angara River and just to show it’s not a one-off, there are four other power-producing facilities on the same river, with stations in Irkutsk, Ust-Ilim and Boguchany.
Lake Nasser | Egypt and Sudan
169 Billion Cubic Meters
The construction of the Aswan High Dam, and by extension the formation of Lake Nasser, came with some uniquely Egyptian challenges. Namely, the fact that a large number of historical sites would be submerged by the filling lake, with the tombs and temples of Philae and Abu Simbel at the greatest risk. Luckily, the Egyptian government didn’t plow ahead the way other countries have been known to. The Egyptians worked with UNESCO to move the sites to higher ground.
Lake Kariba | Zambia and Zimbabwe
180 Billion Cubic Meters
The impressive Lake Kariba is an excellent example of lake creation done right. The dam produces plenty of electricity for the surrounding area, and its existence has given rise to a thriving tourism industry and also increased biodiversity. There was a short five-year period when the rate of earthquakes increased, but that hasn’t stuck around. What has is the tiger fish, tilapia, catfish and vundu, all supporting a strong fishing industry. And the water. A truly awesome amount of water has stuck around. It’s closer to an inland sea than anything else.
