Upgrade each section of the dam individually to increase your earnings. As you progress, unlock a bustling dock in the upstream lake after constructing Dam 2. Once the dock is unlocked, you'll automatically acquire a fishing boat. Send the fishing boat out to the lake, catch fish, and transport them to the dock for additional profits. Use diamonds to unlock new fishing boats and expand your fishing fleet. Dive into the tranquil world of "Dam Builder" and witness your empire grow along with the expanding dam!
