suggestions for flooded subterranean cavern complex (any edition)

Okay so my heroes will soon embark on a quest involving flooded ruin chambers. Specifically, the ruins are Thassalonian (from Paizo's Golarion world), but I'm asking generally: do you know of any cool atmospheric dungeons with the "flooded" theme?

I want to use any dungeon map you find for the following adventure seed:

Wisher's Well. This landmark consists of a 30-foot-tall stone tower with an interior that drops away into a 100-foot-deep shaft ending in a deep pool of water. All manner of monsters dwell in the flooded chambers below, including a tribe of skum, reactivated "ancient Thassilonian guardians" and a slightly larger tribe of faceless stalkers who have been surgically altered to breathe water.

The main thing I would like not having to do from scratch are the dungeon maps. Monsters and Pathfinder 2 stats I can manage.

So any flooded dungeon you found atmospheric, moody and cool (AD&D, 3E, whatever) would be appreciated! Crisp clear color maps would be most welcome! :)

I do not have any instant solution for you, but just take any normal dungeon you like and proclaim that it is submerged now. What would be perfect would be 2 level dungeon with the lower level submerged but not all of the "dry" areas of the upper levels reachable without a dive.
Connect the lower level to your large pool somewhere and there you go. If you retcon anyway that should not be a problem.

Temple of the Ooze in Out of the Abyss is actively flooding when the characters enter; the goal is to escape before it floods completely.

Tomb of the Nine Gods in Tomb of Annihilation has partially flooded areas. Actually, iirc there are more than one partially flooded dungeon in ToA.

I don't think it's very extensive, but I seem to recall some partially-submerged sea caves featuring in the early Sasserine section of Savage Tide. They featured some nasty waterlogged zombie variants who could unhinge their jaws for a vicious bite attack.

UK3 aka Chapter 6 the Final Enemy in Ghosts of Saltmarsh. Two of the floors are flooded.

If you have any of the 4E online Dungeon Magazines, The Last Breaths of Ashenport adventure has a dungeon beneath the temple that is dedicated to Dagon that has some watery parts (and some dry parts). Probably not flooded enough for what it seems you are looking for, but it does have a bunch of water-demon-creature type encounters in it. There's also a full color map for it (although if you used it as-is, you'd need to photoshop out the numbered circles from it.)

The Hidden Shrine of Tomoachan is part flooded.
I ran that for a group out of the Tales from the Yawning Portal 5e adaption and it was great fun.

It loses something with the tournament clock removed, but just the inability to rest because of the toxic air is a great motivator.

The ironically-top level of the Ghost Tower of Inverness?
I found it memorable, for the reversed gravity - and of course, the Ixitxachitls….

While maps from Dungeon magazine scans are too poor quality to be useful, I could of course use the proper 5E maps. But I have already run (parts of) HSoT.

Thanks thou'

Thank you but I don't like 4E maps - they focus on a single encounter at a time.

Maybe I should clarify that the ideal map to me is a clear crisp color map of an entire dungeon level (sized much like a level of the Yawning Portal; that is, rather large) - Mike Schley levels of quality. Despite being clear, it also has this green-blue tinge to indicate the submerged parts (where you need waterbreathing).

The map as a whole is sufficiently bright and clear and of high-resolution to be imported into my Paint.Net program and shown on my television to my players, including zooming in. (I usually add a layer of gray I can erase as the players progress, revealing each part of the map as they go)

I probably wish for the impossible :)

I googled around, but most/all color maps I could find that are clearly "submerged" are unfortunately ruined by heavy dark smudges of blue. They're simply too dark, too color-heavy. Utility must always trump aestethics. That is, while it's important a map looks good, the aesthetics must always take a back seat to clarity.

Here's an example of what I'm searching for. Note the clear colours popping out on-screen. And, of course, the clearly submerged left half :) It's dark, but hopefully not too dark!

One suggestion was Ruins of Azlant, a Pathfinder Adventure Path. The Cathedral of Amaznen is half-submerged, and the map is reasonably clear while showing it as such. Shame there's so little of it - those maps cover only a few rooms, and they are curiously featureless.

True enough. There is a "wide shot" map of the entire cave system (the one I said you'd have to photoshop the numbers out of)... but if you were to expand it up to a larger size for use on a TV it'd probably pixelate too much. That and the fact that the water parts aren't most of the caverns, only specific areas. So not what you need.

The only other idea I have at this point is to somehow get ahold of some photoediting software that allows you to change tint. You could then maybe take a normal dungeon map and select certain sections to raise the blue and green values to make them look underwater. No idea how feasible that would be for you (nor how expensive)... but I've watched my wife use her Photoshop Elements enough times to know that kind of stuff is possible. Good luck!
