How do you build a small raised pond?

Correspondingly, how deep should a raised pond be?

First, measure the area. Bigger ponds are better because you will have more space for fish. But you can put in a smaller pond in if you're short on space. For a standard rectangular pond, I would aim for 1.5m x 2m, and 1m deep (50cm underground & 50cm above ground).

Secondly, how do you build a raised pond with sleepers? Very quick & simple, with very little tools needed.

1. Chose where you want to put the raised pond.
2. Lay the railway sleepers on the ground.
3. Fasten them together.
4. Stack and fix a second layer (if you want the raised pond to be higher)
5. Attach Pond liner.
6. Fill with water.
7. Fill with fish!

How deep should a koi pond be?

A pond for goldfish or water lilies need be only about 2 feet deep for zones 5 or greater. Ponds built in colder areas may need more depth to keep the pond from freezing solid. Ponds built for koi should be close to three feet or deeper to allow these larger fish enough space.
