Flood mod
by Jumedista
Flood Mod adds a controllable flood event that players start and stop with commands, raising water in a large area around a chosen point.
What it does
A flood begins five blocks below the player's position and spreads upward over a 250 by 250 block area around the starting point. The water rises in new levels roughly every 30 seconds until it reaches a maximum height, and the mod keeps track of every block it places. Anyone standing in the flood, players and mobs alike, is in contact with the water and takes drowning damage over time.
A stop command ends the event at any moment, and a separate command clears the generated water so a new flood can be started later. The mod is meant for temporary world events, custom scenarios and survival challenges that leave the rest of the world unchanged. It is described as lightweight and suited to servers, and it keeps the original Minecraft experience intact between events.
Flood Mod is released for NeoForge 1.21.1 only, and the latest file, 1.2.0, was published on 2026-07-19. Installation is required on both the client and the server, because the environment is client and server. The code is not open source: the mod is released under All rights reserved.
Key features

Large flooded area

Gradual rising water
New water levels are added about every 30 seconds until the flood reaches its maximum height.
Cleanup command
A separate command clears the generated water, so later floods begin from a clean area.
