Based on Platonymous's Swim (Almost) Anywhere proof-of-concept, this mod lets you jump into the rivers, lakes, ponds, and oceans of Stardew Valley.


  • Toggle jumping into water using J (customizable)
  • Jump in and out of water by pushing towards the water's edge.
  • Jumping into water puts on your swimsuit, jumping out takes it off.
  • Toggle wearing swimsuit on land using K (customizable).
  • Use tools while swimming and in swimsuit.
  • Travel by water between the mountain, town, beach, and forest by swimming to the map edge.
  • Dive under the ocean and mountain lake using H (customizable).
  • Play with rainbow-coloured fishies and hermit crabs under the sea and big fishes in the mountain lake.
  • Collect resources and treasure from the ocean, mine minerals and artifacts from the mountain lake.
  • Oxygen depletion while underwater is based on player's max stamina (multiplier available in config file) - also, bubbles. 
  • There is rumoured to be special gear hidden in the depths that might improve your swimming and diving...

Artifact spots in the mountain lake look like lily pad shadows... but there's no lily pad above!

To dive, you must have TMXL Map Toolkit installed.

You should install JSON Assets as well, just... because.

You can now create your own Swim Mod Info content packs that add dive info, underwater features, and edge warps to maps! Info on creating Swim Mod Info content packs is here.


Big thanks to Platonymous for the base code of this mod, and the rest of the core Stardew modding community for their great work on SMAPI etc.

Thanks to LemurKat for offering to let me use East Scarpe as the showcase map for the Swim Mod Info API! The underwater map for East
Scarpe is in the optional files, and you'll need the beautiful Escape to East Scarpe as well.

Also grateful to Concerned Ape for SDV and pardeike for HarmonyLib.

Big fish sprites belong to whtdragon and were borrowed from here. Thanks for making them freely available!

Thank you also to those who provided translations! Send translations via discord, please!
