The spawn areas are raised areas that go far to the right. The entire way to the middle of the stage is a ramp that slopes down with few instances of flat land. Few barriers are located on the ramp. After dropping from the spawn region, it is possible to jump down into a lowered area with a tree that has two entrances to the middle. The middle is very open and has one block in the center as cover.
Ranked Battle terrain
In Ranked Battles, specifications for the terrain or placement of objects are different between the modes; these changes create new paths or new objects to take cover behind.
The Splat Zone is in the middle of the stage. The stage is unchanged.
The Tower starts in the middle of the stage, replacing the block normally there. Two small blocks are added around the Tower. The Tower goes left then forward into the opposing team's side. It then goes up the ramp all the way to the goal.
|Splatoon 3 checkpoints:|
|Checkpoint||Location||Timer (Seconds)||Progress Amount|
|1||The first checkpoint is located just before the tower enters the opposing team's side.||6.5||88||75||13|
|2||The second checkpoint is located halfway up the ramp leading to the enemy's base.||7||34||21||13|
The Rainmaker is located on the block in the middle. The checkpoint is found when just entering the opponent's side. The goal is located on the first drop from the opponent's spawn area. A ramp is added there for access. Small uninkable blocks are added near the block in the middle.
The Clam Basket is located halfway up the ramp. The area below the basket is now flat instead of being a ramp. The tree on the flank area is removed and replaced with an inkrail, allowing easier access to the clam basket. The block in the middle of the stage is replaced with a Bumper.

- This is the only multiplayer battle stage in Splatoon 3 to be set at sunset rather than midday.
- Brinewater Springs is said to let anyone use their services for free during a Splatfest; however, Frye suggests that most have been unable to take advantage of this, due to jellyfish booking every nearby inn solid.
