this mod introduces real flowing rivers, with a true current, to Minecraft 1.7.10. These rivers are generated in the world using custom non-decaying flowing blocks and are much larger than anything the player could create using buckets. They originate in multiple sources and flow down the terrain through slopes and waterfalls, joining together into wider rivers until they reach the sea (or the old-style sea-level static rivers, if those exist in your world).
Keep in mind this is still an alpha release. Rivers are fairly short and don't always appear in ideal places, but this will improve in time. Please see the FAQ section below for explanations of various known issues, including tips on finding a river. Let me know of any other bugs you encounter or suggestions you may have.
Note: the vanilla Minecraft terrain generator has low average altitudes, which makes for rather flat rivers. For best results, consider using a custom terrain generator capable of higher average elevations, such as ATG or RWG
