Deep Streams

• A deep stream is simply an

extension of the pond itself. By

adding a deep stream to a pond,

you allow the fish from the pond

to swim to other areas that would

otherwise not be possible. One

important construction technique

you will need to master, is a

double-seam.

Excavated soil from pond & stream

Otherwise, do a combination of deep stream with fast upper stream.

Fig. 15-1 An often overlooked part of stream construction is the thickness of your

waterfall stone. Water will eventually seep through the foam joints if the pumps

are off for prolonged periods of time. The water will slowly seep around the thick

stone, resulting in water loss equal to the thickness of the stone.

Fig. 15- If your only option is a thick waterfall stone, use the above method.

Fig. 15-3 By using a thin stone, the situation can be easily remedied.
