Aqueducts
The Aqueducts mod provides an innovative solution for transporting water over long distances in the Minecraft world. Instead of traditional methods that may be limited by the game's mechanics, aqueducts allow you to create extensive water channels for various needs.
Although the water in aqueducts is not a full-fledged source in the classical game sense, it retains many practical functions. You'll be able to freely place and navigate boats along such channels, as well as collect water for potion-making and operating various pipe systems.
It's important to note that this mod changes some basic water mechanics - buckets don't exist here, and the ability to create new water sources by connecting two existing blocks is disabled.
