Thanks for your feedback! I’m actively working on the mod and things are changing quickly. I suppose you’re referring to version 0.0.2 — since then, some changes have been made, but the main idea remains the same.
The mod takes full control over lake tiles. Once a pump is placed, it initializes the lake as an equal-depth pool of 1000 liters per tile. As the water level drops, the tile type changes according to these thresholds:
700+ – deep water
500 – water
200 – deepwater-green (shown as gray-blue)
5 – water-green (shown as yellow)
< 5 – sand-1 🙂
Regarding compatibility with The Shallows mod: in principle, it should be possible to support it. I’d need to introduce a different bottom-depth parameter. That should be fairly straightforward, though I’m a bit concerned about shallow areas depleting too quickly. Still, I’ll give it a try.
As for the sand behavior: yes, that’s intentional. After water turns into sand, a small amount of water remains in the sand. I agree it feels a bit inconsistent visually, and I’m still experimenting with how to make this look and play more coherent.
