In the Separate Ways DLC expansion for Resident Evil 4, players navigating Ada Wong's story encounter various unique optional requests from the Merchant. One of the most interesting assignments is the Lord of the Waterway request, which requires finding and catching a gigantic mutated fish hidden in the deep sewers. Completing this objective yields valuable Spinels and Pesetas that help significantly with gear upgrades.
Starting the Lord of the Waterway Request
Players can accept this side mission in Chapter 5 after reaching the dark subterranean drainage channels. The request note is posted near the Merchant's shop right before entering the flooded tunnels. Reading the blue note provides initial instructions to locate and harvest the massive creature living beneath the facility.
Draining the Water and Navigating the Tunnel
Before you can reach the target creature, you must solve a brief environmental puzzle to clear the flooded passage. Locate the control valve nearby and interact with it to drain the water from the lower floor. Once the area is drained, drop down into the newly opened pathway and crawl through the small opening under the hives.
Finding and Catching the Big Fish
The giant fish swims in a small pool located at the end of the narrow crawlspace. Utilizing a Biosensor Scope attached to a rifle makes identifying the shadowy silhouette much easier in the dark water. For a detailed walkthrough of the area layout, check out this Lord of the Waterway Location guide to pinpoint the exact spot. Once spotted, shoot the fish with any firearm to catch it and add it to your inventory.
Claiming Your Merchant Rewards
After acquiring the creature, travel back to the nearest Merchant shop to sell the fish. Delivering the fish fulfills the request conditions automatically, granting you 8,000 Pesetas alongside 8 Spinels. These rewards can then be exchanged for high-tier weapon upgrades, treasure maps, or exclusive items.
