[XND] Watermill Tweaks Mod

Author of the [XND] Watermill Tweaks Mod: mlie

[XND] Watermill Tweaks Mod enhances the vanilla watermill generator by turning it into a more nuanced and dynamic power source. It introduces temperature- and season-based power variations, increases base output, and adds a new river-related incident, making watermills more interesting and strategic compared to other power generators.

This is an update of XeoNovaDan’s mod.

[XND] Watermill Tweaks Features

  • Increased base power output: Watermill generators now produce 1400W instead of the vanilla 1100W.
  • Temperature-based variation: Power output is reduced at extreme temperatures to simulate viscosity changes and evaporation.
  • Seasonal variation: Power output increases by 20% in spring, 10% in fall, and decreases by 30% in winter.
  • River type scaling: Cold temperature thresholds vary depending on whether the map has creeks, rivers, large rivers, or huge rivers.
  • New incident: Turbulent Waters: A rare event that boosts watermill output by 50% while gradually damaging generators due to debris and stress.
  • Environmental weighting: Turbulent Waters is more likely on large and huge rivers, and on maps with high rainfall.

Temperature mechanics

Power production is reduced below 0°C (32°F) and above 50°C (122°F). At 60°C (140°F), output is halved, and at 90°C (194°F) or higher, production stops entirely. Cold thresholds vary by river size.

Technical details

  • Powered by the Harmony Patch Library.
  • Includes improved in-game descriptions and letter text when turbulent rivers are active.
  • Adds support for Vanilla Furniture Expanded – Power.

Compatibility notes

  • Can be safely added to existing savegames.
  • Removing the mod mid-save may cause issues if Turbulent Waters is currently active.
  • Designed to work with all other mods.
  • No known hard incompatibilities.

If you encounter issues, test with only [XND] Watermill Tweaks Mod and its requirements enabled. If the problem disappears, reintroduce other mods gradually. Always provide a full output log and clear reproduction steps using the Log Uploader. For best support, use the Discord error-reporting channel. Do not report issues via discussion threads. If you find a fix, please submit it to the GitHub repository. Use RimSort to manage your load order.
