Many of the quests in Arc Raiders can be straightforward, while others can take players multiple runs to figure out what they have to do. The Water Trouble quest that players can pick up from Celeste falls in between those two.
It's not that complicated and time-consuming to complete, but finding the Flood Access Tunnels can be difficult, especially if players haven't visited the surrounding area before. The guide below offers a step-by-step walkthrough of the quest and the rewards that are associated with it in Arc Raiders.

Water Troubles Quest Guide in Arc Raiders
The quest is for the Dam Battlegrounds map, and you can run a free loadout if you don't want to risk losing your items. After you load into a match, make your way to the Red Lakes Balcony, which is located around the middle of the map, near the Control Tower. If you are on the balcony, then go down any of the ladders here, and if you are already down, then simply head northwest. You will spot a tunnel that you can climb up and enter.

With the first objective completed, make your way inside the Flood Access Tunnel, where you will have to sample the water. There is no need to go above the zipline or anything, as the water is right in front of you, near the pipe that is submerged in the polluted water. Interact with the water, and this will complete the quest.
With the quest completed, you can either run straight to the extraction point near the Testing Annex if that is up, or you can loot the Control Tower and Research & Development.
R&D has a lot of medical loot and trinkets that you can fetch a good price if you sell them once back to the main menu.
The extraction points can have multiple Wasps or Hornets roaming around, so always hide inside a building or bushes while the elevators arrive on the topside. Once you have successfully extracted, go to the Vendors tab and claim the following rewards from Celeste:
- Mechanical Components x3
- Simple Gun Parts x3
- Steel Spring x3
