Reservoir
Java mod listed for Minecraft 1.20. Downloads from the MC Java Mods app on Android.

This mod adds a practical new block designed to make large-scale water terraforming much easier in survival mode.
The Reservoir can be filled with water up to 8 times, with each stored level increasing its effective range (up to 8 blocks). When activated by a redstone signal, it releases its stored water into the surrounding area and beneath itself in a half sphere shape, filling the suitable spaces with water while stopping at terrain and waterlogging where expected.
The block preserves its stored water when broken, allowing a filled Reservoir to be picked up, transported, and reused elsewhere without needing to refill it.
This mod is intended to provide a convenient survival-friendly alternative to manually placing dozens or hundreds of water buckets while still feeling vanilla-friendly.
