I will post pictures if anyone wants them, but lemme just tell you what I did.
Started a new area, built a base near the mountain.
I noticed a small hole near base, figured I needed to farm (Still haven't yet =P)
Using buckets, I brought the water from the closest water source to the hole, and made a small pond.
Then, I dug a river and filled it to the other water source.
Then, I wanted a huge waterfall, so, close to the original base, I dug out a river to my pond, then up at the top, I made a small spring and a river leading to the waterfall.
After I was finished, I dug out behind the waterfall and made a small cove, which is my base now.
