"The Casiquiare river, also known as the Casiquiare canal is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America. As such, it forms a unique natural canal between the Orinoco and Amazon river systems. It is the largest river on the planet that links two major river systems."

"Isa Lake in Yellowstone National Park is believed to be the only natural bifurcated lake in the world to drain backwards into two oceans. Its western drainage is to the Atlantic Ocean via the Firehole River, while its eastern drainage is to the Pacific Ocean via the Lewis River."
