Waterfall Limit
by TiTi
Waterfall Limit caps how tall natural waterfalls and lavafalls can grow, so vertical fluid columns stop before they reach the ground far below.
What it does
When a vertical flow goes past the height limit set in the config, the fluid disappears there and a puff of smoke rises from the spot, similar to vanilla evaporation. Oceans, rivers, canals, lava lakes and lava pools are left alone, and the terrain generation the author describes stays natural-looking.
The limit is set in a TOML config file, and the mod is lightweight, aiming at minimal performance impact. Players on a multiplayer server get the same behavior, so the server and every player need the mod. Waterfall Limit is published for NeoForge only, across 11 release versions 1.21.1 – 1.21.11, and the latest file is version 1.0 for 1.21.11. The code is released under the MIT License, so it is open source.
Key features
Height-limited vertical flows
Natural waterfalls and lavafalls stop once they exceed a configurable maximum height, which prevents endless fluid columns.
Exposed-flow detection
Only vertical fluid columns surrounded by air on four horizontal sides are targeted, leaving other water and lava untouched.
Evaporation particles
When a flow reaches the limit, smoke particle effects appear in the style of vanilla evaporation.
TOML configuration
The maximum height is adjusted through a TOML config file, so server owners can tune it for their world.

How it compares
Tyr's Fluid Void Stuff is a NeoForge mod for 1.21.1, open source under the GNU General Public License v3.0 only, and either side can run it, so it works on a client alone, a server alone or both. Lavaflow is open source under the GNU Affero General Public License v3.0 or later and covers Fabric, Forge and NeoForge for 1.21.4 – 1.21.11, where only the server needs it. Mountain World is a NeoForge server-side only mod for 1.21.1 under All rights reserved, so it is not open source.
