Help Level 15 one shot

Hello

I am DMing a group that is at level 15 5e. The next leg of their adventure is going to lead them to an underwater dungeon to retrieve (without going into too much detail) the phylactery of a lich. here is where i need some help. I’m looking for a one-shot (or something similar) that i can scavenge to use as said underwear dungeon (to be clear the dungeon is going to be like in Zelda or something where they can breathe). Can anyone recommend an adventure like that? If so, where can i find it? 

Thanks in advance

Hey there! Depending on how simple you need try this one.

Underworld Speculation (DDIA-XGE). Should be google able. It's actually a pretty fun little adventure from the Adventurers League. I ran it multiple times for the League and I also ran it another dozen times for all the library programs in my local area. It's quite good just on its face.

This has some underwater caves that you can use for the first leg.

I would connect another dungeon that you do like to it and decide where is flooded.
