Aqua Laguna is an annual high tide that takes place in Water 7. It engulfs the lower part of the city with a huge wave. Every year during the Aqua Laguna everyone is evacuated from the lower parts of Water 7. After each Aqua Laguna, part of Water 7 sinks. This causes the city to constantly receive repairing. Oda explained in an SBS that this came from the Acqua Alta (High Water in Italian), a similar phenomenon (but much less important) that happens in the Adriatic sea, and so in Venice, where it is an important problem due to the fact that the city itself is on the Venetian lagoon.
Since the Aqua Laguna is becoming more and more violent every year, the ground level of Water 7 is sinking day by day. To counter this, after the raid on Enies Lobby, mayor Iceburg decided to convert Water 7 into a ship, in order to prevent the city from being destroyed.
Anime and Manga DifferencesEdit
In an anime filler episode, it was shown that on the roofs of the houses in the lower part of the city lies salt from All Blue, as the Aqua Laguna carries water from all of the world's seas. This salt improves every dish, and Sanji stockpiled it before leaving. However, this is non-canon.
- ↑ SBS One Piece Manga - SBS Volume 38 - Fan question: Hello, Oda-sensei!!! I have a question. On TV, they were saying how the "City of Water" Venice has a high tide called the "Acqua Alta", which forces all the townspeople to wear long boots!! Is this what the Aqua Laguna in Water 7 is modeled upon?.

- ↑ One Piece Anime - Episode 319, the salt left by Aqua Laguna is said to be from the All Blue.
