John & Yvonne from Oklahoma City, USA, had a swimming pool 38ft x 18ft and it was four feet deep at the shallow end and twelve feet deep at the other end, and they decided that they would convert this to a pond with the idea of having a few koi.
Most of this text was written by John, and the scanned photographs sent by e-mail shows his progress with this project.
There will be two 3,000 gals/hr pumps with 3 filters (two submersible and one biological), and when the water leaves the filters they will be going to various waterfalls.
This project has got John so exicited he just can't stop working, and he even comes home from work during his lunch break to work on the pond.

The photo on the left shows the pool before construction of the pond, and a saw has been used to cut slots into the bottom in numerous places to allow drainage. The original pool had a fibreglass shell and was much easier to do than if it had been concrete. On the left is the first of the dirt (soil) being put into the pool.

The machine John used to move the dirt, and this gives a good idea of just how much dirt was needed. Approx 155 tons or 300,000lbs.

The pool has been filled with dirt, and now the digging out of the ponds is taking place.
