I'm probably not the first to suggest this but this game really needs better water. My suggestion would be to take a page from 2006s "Wildlifepark 2".
Essentially you place a water source and a drain. Then you run a liquid physics simulation, doesn't even need to be a good one. Have the water for the simulaton spawn from the water source and increase the amount of water spawned until the water surface reaches the height of the drain and then freeze the simulation at that point. And have objects like rocks, walls, roofs, etc, be impermeable to the water. It would be nice if the simulation would automatically recognize when the water is flowing downhill or falling straight down in a waterfall and add corresponding effects but those can just be added by hand later so that's a nice to have but not neccesary. Water surfaces created this way would not just look much more natural, one could even make really nice loking waterfalls without having to cheat with effects, it would become possible to build full underwater structures, it would become possible to alter a water surface without having to first delete the water and then fiddle around with the terraforming tools until you can place it again, you would no longer have to fully plan out your water surface before actually placing the water and so much more.
PLEASE! I don't care wether that comes as a dlc or just as part of the regular updates but please. I'm tired of this crappy water.
