Description
Upstream, the ultimate river upgrading mod!
Tired of the old small thin and sometimes waterless rivers vanilla offers? Upstream is the answer! Upstream is a river overhaul mod that removes the old vanilla river generation and replaces it with new endless and wider rivers. With 2 vast configs, the 1st letting you pick and choose what river biomes(modded and datapack!) go in which biomes(modded and datapack!), the 2nd letting you control the wideness, generation frequency, and much much more! So what are you waiting for? Try it out!
