I have a question: Are there any worldgen settings that particularly encourage the formation of lakes and rivers over oceans, besides the obvious minimum ocean settings?

[TeDDD]

I would also like to know this.  Decrease drainage?  Increase rainfall?  I want me some Freshwater Lakes.

[NRN_R_Sumo1]

fresh water lakes are too rare in my oppinion.
But then again I come from southern ontario where we are surrounded by the worlds largest fresh water lakes..

No you're right, there are usually only 0-1 freshwater lakes per world....

There are a lot more than that irl.

irl theres only one world and every other planet doesnt have water at all

IRL there are billions of stars with planets circling them, the universe does extend past pluto you know?  This means that it is not only possible but probable that there are many other planets very similar to ours, lakes rivers and all...

As for water on other planets in our solar system, well science has proven there is water on quite a few of the other orbital bodies circling the sun, google europa for one example...

Try messing with the [RIVER_MINS:300:280], how many puny fish-happy streams are around.
Less streams and lower drainage might give lakes. Hopefully evil lakes with zombie swans and pelicans.

Trying medium region... put bias on low drainage. From 70 rivers to 12 rivers: no luck.
From 70 rivers to 90 rivers: two lakes. With elven names.
180 rivers: two puny lakes and one frozen lake-like glacier next to main glacier. And.. looks like a freshwater sea far south.

Increasing low-drainage mesh thingy. From 8-6-1-1-1 to 1000-6-1-1-1. Got TEN tiny lakes where the mountains surround a valley.
North edge, a huge light-blue (probably freshwater) sea.
Roll world again: got 8 lakes. Thick river bumps into north edge, makes lake. I see. The edges of the world are tall cliffs.
Roll world again: zero lakes, 3 seas.
Roll world again: zero lakes, one huge sea.
Roll world again: zero lakes, one huge sea.
Roll world again: four lakes nestled by mountains, two seas.

Increase mountain peak count: change from 5 to 20. Seven lakes, zero seas.
Eight lakes, two seas. Seven lakes, three seas. Zero lakes, huge sea.
Zero lakes, two small seas, one huge low desert. Six lakes, one big half-frozen sea.

So, cold areas and scorching areas hurt your sea and lake formation. One might want a everywhere-temperate world with even rainfall for lakes.
(changes rainfall variance to 55 and temperatures to 45-65.) 3 lakes, 1 huge sea.
(78 variance, 50-65) no lakes, giant central desert, neat. Roll: 2 lakes, 5 seas. Roll: 0 lakes 2 seas.
(change to 70 mountain peaks) 2 seas, central mountains. 1 sea and 1 desert ex-sea. Sweet evil forest in the big desert.
(temperatures to 40-55) 3 small seas, 1 ex-sea.

(several changes) Whoa, the world has a central very evil mountain range. 3 seas. Gotta go view that very-wide rivermouth.
(embark with 8x8 area to see wide river) 24-wide river at z-level -7. -2 Level's river drops in a grand waterfall to the -7 river! Impressive. And had a cavern collapse at start. 72 fps and everybody idles except the carp. This place is too peaceful. (normally 320+ fps at 3x3 embark)

Check your rooms screen. Frame one cave-ins are fairly rare; they almost always happen in the presence of a (the rest of the text is indecipherable)

I concur. I enforce this on all my world gens and almost always end up with dozens of freshwater lakes (and massive rivers with awe-inspiring waterfalls). I suppose if you also enforced Tomitapio's medium temperature, low drainage, and high rainfall rule it would increase the frequency of lakes (and swamps) drastically. Or maybe just elves...

Then, if you force extra mountain peaks, caves, and volcanoes, you could get some truly interesting gens.

[TeDDD]

Excellent.  Thanks for the replies and suggestions.

On medium or large region?

[Dora Feddy]

I usually get a good variety of lakes when I gen a large region. I don't even mess with any parameters.

Most of the lakes are probably going to be small one tile areas on the regional map, and larger lakes tend to be nestled in large mountain ranges.
