Newest reservoirs in
The year that a reservoir was first filled to the reservoir’s normal elevation – or the year that a natural lake was first dammed – is the determining factor in the age of the body of water. A large reservoir can take more than a year to fill after its dam is first closed. You can find many of the the world’s newest reservoirs on LakeLubbers in the comparison table below.
