A set of 3 objetcs (CAW enabled) to build that beautiful stream you have ever dreamed of:
- a 20x20 water lake (shiftable, under Decor misc, 0§);
- a stream section, 9x18 (shiftable, under Decor misc, 0§);
- a riverbed boulder, 12x8, two variations (shiftable, under Rocks, 1§).

“Moveobjects on” cheat is required to place them, because, for being shiftable, they should need a wall for their placement.

The two water objects are cloned from the distant river in Shang Simla (the chinese scenery of World Adventures EP, so you need it for them to work).

Sims will walk through the water objects of the stream, so it’should be better (if built ingame and not in CAW) to border the stream with rocks, fences or other objects, so this will block their path.

In CAW, the stream section and the below boulder, can be placed with identical coordinates and angle.

The other boulders in the picture come from this set at TheSImsResource.
Sounds, steam and splash effects are added using few fog emitters (a useful shiftable version is available at MTS) typing “waterfall_2_short” for the waterfall effect, and “waterfall_1_shortsplash” for the steamy effect at the end of the stream
