WaterLevel

The WaterLevel proxy will add sound effects and blur if the player is inside any ladder beneath it; to make actual swimmable water, simply use a ladder volume. This will not add any visual effects to your water, however, which you will have to add yourself using other unity tools. Unity comes packed with some water assets which you can use for this purpose.
