The Floodgate key (formally Watergate Key, Dam Key) is a key item in Dragon Quest II. It was stolen from Slewse by Rogue Fastfinger.


The key can be acquired by finding Rogue Fastfinger in the village of Burrowell. Rogue is hiding in a secret passage within his prison cell. By probing the back of the cell, the secret entrance can be found. Rogue gives up the key when talked to by the heroes.


The Floodgate key has only 1 specific usage. It is used in Slewse to open the floodgate located in the northwest corner of town. Opening the floodgate causes the river to flood, providing access by Ship to the Tower of the Moon.
