I would like to create a creek or spring that isn't very deep where sims can splash around. Maybe knee deep if your are an adult.
I'm trying to create a story, where my kids sim can go to a creek, outside the community, with an abandoned water mill on the side. Maybe creating as its own destination or town but isn't a town, more like a secluded area. If not possible, is it possible in either sims 3 or 4?

In Sims3, sims can walk through the 'ocean' when it's shallow, if I remember correctly. That might work?

Only way to do this is to make it like a swimmable lake, but with it not being as wide as a lake your animations might look a bit off! https://modthesims.info/t/245795

Or else you could make a two tile pool and use the curve pieces to make it look like a Creek, gets some dirt walls and floor for inside pop foliage around it and use the invisible get in/out pool object so there's no ladder https://modthesims.info/d/608173/in...s-swimming.html
