The Bloomin Bog Water Gardens

STREAMS:

A stream can flow anywhere you want and may contain planting niches, or just stone. Streams are often used to join two ponds together, or to take water from a bottom pond to the top of a waterfall.

A stream requires a rubber liner, underlay, and sand for cushioning and liner protection. Try to use just one piece of liner for the stream, but if you have to make joins, start at the bottom of the water course and generously overlap each piece in the direction of the water flow. To prevent leakage, seal all joins with rubber seaming tape.

The liner must be secured at the edges with soil or rocks, and must always be higher than the water level.

The following tips may be helpful:

Mark out the run of a stream using wooden pegs and knock them into the ground so that all their tops are level. Use a spirit level to confirm the level of the land.
For the best effect, a stream should be laid to a gradient of between 10 and 30 degrees.
A stream bed needs a drop of about 2ins every 10ft to ensure a downhill flow.
The careful position of rocks in a stream bed can create interesting flow patterns.
Size the pump according to the pond’s volume, the length of the stream, and the desired flow rate (see chart on page 11).
Splashing water from a stream will contribute to evaporation.
