Water via trigger or jass possible?

[NRN_R_Sumo1]

Hello, this is my first post on the forums.
to keep it simple and not a tonne of reading for a single question and (hopefully) an explaination or direction for a tutorial..

Is it possible to set water in the editor via triggers? I am making a terrain generator for a wilderness survival map and I have the terrain looking pretty good, but I'd really love to be able to toss around some lakes or ponds, rivers or canyons would be great but those would seem a tad difficult for me at this point.

I dont know much Jass, but if I need to learn a little more than I know I am completely fine with that.

help pwetty pwease?

Alright, I figured out a system for it and I feel silly now.

I randomly generate the land rather than the water, and it works out great.

Solved.

(just a little sample of the swampier areas, its actually pretty good looking in most parts due to tweakings)
