Baie D'Urfé
A large water feature beside a new pool;
before, the customer had tried to build it himself, but the liner has to under the rocks to make it work.
Photoshop
worked photo to show how it could look;

So we had to tear it apart and rebuild; a waterfall with a pond and a bog.
Here you can see the echo chamber:
again, I also had to build a small mountain behind it to justify having a waterfall and stream
building the stream above the waterfall;
I use 2x8 to frame the stream;
what it looks like from a distance;
Next we enlarge the pond on the other side;
the customer puts a wrench in the works, they want to increase the size of the patio between the pool and the pond. That means getting large heavy flat rocks (for stability) and building a wall (for security) in the water. You will get the feeling that the water flows under you. This side of the pond is more than 4.5 feet deep. He wants to snorkel in it!
Finished, the pond is a bit cloudy but that will clear up in a few days
The customer has already put in more than a dozen koi and goldfish 1 day after filling, only the bridge is missing;
a day or 2 to clear-up the pond and voila:
The plans are now to add another pond to this one on the other side of the Gazebo and bridge.
