The short answer
Read the map board before you explore. It stands near the spawn beach, opens with E, and labels the island as home, the surrounding shallows as reef, and a distant landmark as old wreck, with a straw icon marked slurp! and a handwritten note about something rusted under the sea.
Pair that board with the depth gauge post at the shoreline, which is marked 0 m at the waterline and continues down past -40 m. Together they are the game's own answer to where am I and how far down have I got.
Place names the game uses
| Target | Label | Where it appears | Evidence |
|---|---|---|---|
| Coastal Shallows | Coastal Shallows | HUD line: Next: Coastal Shallows at -1 m | Observed in the HUD on a fresh save |
| Home | home | Centre of the map board, drawn as the starting island | Observed on the map board |
| Old wreck | old wreck | Upper edge of the map board | Observed on the map board; also named in the official description |
| Reef | reef | Ring around the island on the map board | Observed on the map board |
How the depth gauge works
The gauge is a wooden post at the shoreline with painted marks at 0, -10, -20, -30 and -40 metres, and a flag that sits at the current water level. As you drink, the flag drops. It is a physical version of the number in the top right corner of the HUD.
The HUD also states the next milestone outright. On a fresh save it reads Next: Coastal Shallows at -1 m, so the first unlock is one metre of drop away, not a hidden threshold you have to discover.
What the island does as the water drops
- Rocks you swam past become walkable paths.
- Chests and treasure appear in the newly exposed sand.
- Ground that was deep water becomes somewhere you can stand.
- The map board's own note hints that something is rusted under the sea, which is the game pointing at the wreck rather than at a secret.
Map questions
How do you read the map in Drink the Ocean?
Stand at the board near your spawn point and press E. It opens a hand-drawn map with home, reef and old wreck labelled, and closes when you interact again.
What does the depth gauge measure?
The current sea level, marked from 0 m at the original waterline down past -40 m. The flag on the post drops as you drain the ocean.
Are there other areas beyond the reef?
The official description says the water eventually drops far enough to reach the shipwreck and whatever is below it. Anything past that point was not observed in this research pass.
