Link can reach the Floodgate Keeper's House immediately upon entering Spool Swamp from the Holodrum Plain. Once inside, Link can speak with the Floodgate Keeper. After finding out that Link wants to reach the Swamp, the Floodgate Keeper confesses that he has lost the Floodgate Key to open the floodgates.
At the bottom-right corner of the house, there is a small lever and Link can strike it with his Sword. This causes it to lower the water within the house, as well as the small pond just outside. Inside the house, lowering the water reveals the Floodgate Key. After acquiring the Key, Link can speak with the Floodgate Keeper once again and he gives Link a hint that he must use the passage outside to reach the keyhole that opens the floodgates.
After Link has acquired the Floodgate Key, he can speak to the Floodgate Keeper within the house and he asks Link if he has opened the floodgates. He gives Link a hint that the vines get so overgrown in the Summer. This information is useful in figuring out how to enter the third dungeon of the game, the Poison Moth's Lair.

- ↑ "Did you open the floodgates? The vines there get so overgrown in summer!" — Floodgate Keeper, Oracle of Seasons.
- ↑ "Link! Are you all right? Actually, I am the nurse of Hyrule's Princess Zelda. And Din's no dancer either. She is actually the Oracle of Seasons who wields control over the forces of nature. Zelda has mystical powers that told of a curtain of shadow drawing around Din. I was instructed to take her to Hyrule in secret." — Floodgate Keeper, Oracle of Seasons.
