This page of the Resident Evil Village guide contains the walkthrough of the large reservoir location on the way to Moreau. In the following guide, you will learn how to avoid the attacks of the giant fish, how to get through the flooded area, where to get the crank and how to solve the Sluice Gate Controls puzzle.
Exploring the initial part of the reservoir
You'll be able to fully explore the reservoir after you've found the boat key in the cave and have used it to start its engine. The game, unfortunately, will not allow you to swim around the entire reservoir limitlessly, as you will encounter numerous barriers very quickly.
Eventually, you must enter a dark cave with a small pier. Mooring the boat will lead to an important cut-scene involving characters from the beginning of the campaign.
Moreau will inform you that from now on, you'll have to avoid being devoured by a giant fish swimming in the reservoir. Get to dry land quickly.
Soon after you begin exploring the snowy surroundings, you will reach a gatehouse. It contains the Sluice Gate Controls, but due to a power outage you will not be able to solve the puzzle right away. While exploring, you'll also come across a typewriter and the Duke - this is his new temporary location while you're in the Reservoir area.
Getting the crank
A drawing on the wall inside the building is a hint - you will have to reach the nearby Windmill and use the crank to guarantee power supply to the Gatehouse and activate the sluice gate controls.
There is another path leading from the watchtower - start exploring it. It will lead you to the first windmill.
Trying to interact with the Windmill Turntable mechanism will end with the crank getting broken and you'll be forced to find a replacement crank.
Use the ladder inside the windmill. You will reach an area with partially flooded buildings.
Bring the platform down in the spot marked in yellow. Starting here, you must avoid being devoured by the giant fish. This means running across floating platforms at the right moments, preferably right after the monster has swum under such a spot. Sprinting will help you get to the new stable ground as quickly as possible, where the giant fish can't reach you.
Keep moving forward and remember that you don't have to rush anywhere if you are standing on a stable object. In order to avoid being eaten, stay in a safe place and wait until the giant fish swims under the spot where you're supposed to go.
In the meantime, shoot at the structure marked in yellow, as shown in the picture. This will allow you to move on.
Ethan will get to a larger building and here, you'll have ti push the carriage shown in the picture.
Reach the metal box. After opening it, the main character will be able to pull a yellow lever.
You're about to solve an environmental mini-puzzle in which you must pull levers and make the platforms temporarily resurface. Start by pulling the blue lever (picture 1). Run to the right and pull the orange lever along the way (picture 2).
Ultimately, you must reach the white lever (picture 1). Your task will be to get to the right area visible in the distance. You can try to run there in one go, but it is risky - if the platform falls down with Ethan standing on it, then you will die. It will be safer to pull levers of other colors again along the way. Picture 2 shows your destination - the blue, orange and white platforms must form one long platform.
Once again, you'll have to run across wooden footbridges floating on the water and avoid being eaten by the giant fish that is hunting Ethan. Don't rush and take advantage of the fact that you can stop for a moment once on a stable ground. This will make it easier for you to wait for the fish to swim away.
Ethan has to reach the next carriage and push it.
You will reach a new large wrecked building. There is another carriage to push.
Jump down and when you reach a new slimy barrier, get rid of it any way you can. A new path will lead you to a ladder. On the higher platform, there is an interactive lever.
Move forward, destroying the new slimy barrier along the way. In one of the next areas, you have to hit the padlock shown in the picture to get the ladder down.
Go upstairs to get to the Windmill Turntable mechanism. You will find a crank that the main character can pick up. Use the crank on the mechanism right away.
Solving the Sluice Gate Controls puzzle
Take advantage of the new ladder and after climbing up, you have to slide down the rope.
Land on the platform of a new windmill. Use the newly acquired crank on its mechanics. This will restore the power supply.
You can head back to the Gatehouse watchtower. Once inside, have a look at the previously unavailable Sluice Gate Controls. There is a puzzle associated with the sluice. A hint regarding solving it can be found in a note located to the right of the control panel (the note rotated 90 degrees to the right).
The solution to the puzzle is shown in picture 2. You have to press the panel buttons of different colors until each one changes its color to the right one:
- First horizontal row - blue, white, orange
- Second horizontal row - white, orange, black
- Third horizontal row - orange, blue, blue
You can now pull the lever and drain the water from the tank, thus completing the puzzle.
