Great Lake

The Hogwarts Lake is a large body of water located to the south of the castle. It is about half a mile in diameter and the Hogwarts plumbing network drains into it. It is home to a Giant Squid, grindylows, and a colony of Merpeople. The lake was also used as the site of the Second Task of the Triwizard Tournament. The Slytherin common room is beneath the lake, accessed through an entrance in the school dungeons. The Chamber of Secrets is also thought to be beneath the lake.

The lake is very often cold, but Viktor Krum is known to have swam in it, apparently not affected by the low temperature. (Although this is probably due to the fact that his school, Durmstrang, is located in a place that is even colder.) Harry Potter, Fleur Delacour, and Cedric Diggory also swam in it.

In 1997, Albus Dumbledore was laid to rest in a white tomb on the shores of the lake following his death in the Battle of the Astronomy Tower.
