Description

# Underground Rivers **Underground Rivers** is a worldgen mod that adds underground rivers to your world. ## Description Tectonic has underground rivers as a feature, but this mod adds them to vanilla terrain with no other changes. They're a complete rewrite from the ground up, meaning there's better entrances and more variation then ever before! Underground Rivers relies on the [Lithostitched](https://modrinth.com/mod/lithostitched) mod for compatibility purposes, making the mod work with other worldgen mods like Biomes O Plenty, Nature's Spirit, and even Terralith!
