First start by going to the landscaping tab, then select the pull tool.
Then make sure that the size of the tool is 11m.
Then go to the place you wish to have ur waterfall.
Make a lump in the land with the pull tool, insuring that it is not to high or to low.

Now use the ''Flatten to Foundation'' tool, and carry it over the lump.
Make sure that the circle is about 4 times bigger then ur tool's width.

Now we're building the lake part!
Go into landscaping and select the push tool.
Make a dent in front of ur circle mountain.
Then use the ''Flatten to Foundation'' tool and make a pond in the size you desire.
Now make a little cave into ur circle mountain form.
Now use the push tool and clean the edges of the cave. Then clean the inside aswel, to make a from that you're happy with.

Now go into the ''Barriers'' section.
Select the glass barrier.
Now put it at the entrance of the cave.
Then we're going to make it double the length.

Now select the landscaping tab.
Go to water.
Now select ''Rough Water''.
Now add water to the cave where the glass is.
Now lower the glass until its in line with the water's edge.
Now add the water into the pond.

Now go into the nature tab, and go to rocks.
Now choose the rocks you wish to use. (I always recommend that you use flat rocks, bc they work better.)
Now place them right against the glass barrier, insuring that they cover it, but make sure they don't stick out either.
Now decorate the edges of the hill and cave formation.
Now decorate the top of the round hill formation with ur desired items.

Ok, go into the ''Construction'' tab.
Now go to ''Effects''.
Now click ''Water''.
Now click the search bar and type in ''Top''.
Now select the 10cm top water.
Rotate it and place it ontop of the rocks covering the barrier.
Make sure that the water is in line with the rock barrier. (I suggest not to pause the game while you do this, bc the Water Effects won't show then.)
Now add multiple of this item, so that i covers the whole top.
(I forgot to screenshot the rest, so just read carefully.)
Now go to the search bar and type in ''Mid''.
Now select the 10cm one. (You can also use the 5cm one, bc sometimes the 10cm struggels to work.)
Now get the ''Mid'' ones, and place them or under or with the ''Top'' ones.
Add the ''Mid'' ones in a row, so that they cover the whole section.
Now go to the searchbar and type in ''Bottom''.
Now get the 10cm ones, and add them at the bottom of the rock barrier.
Make sure they go in a neat line across the barrier.
Now go to the search bar for the last time and type in ''Rapids''.
Now use ur desired one.



Now you can add and remove certain items and make it ur own!
