flooding of an area to make the lake, a land area that might be used otherwise. The
more incised the stream, the smaller the lake.
3. Side Channel
This is an alternative to a dam and has the advantage of being simpler to construct
while providing a good degree of stream flow control. It is suitable for incised streams
with soil banks. Dig a trench along the bank parallel to the stream, starting at the
upstream end where water can enter. The trench should follow the contour, i.e. be
almost horizontal. Make the trench long enough so that when you have finished it is
around 1.5 meters above the water surface in the stream below. Excavate this area so
that the water can enter the trench, flow along it and exit back into the stream below.
Some modifications may be required to achieve the required flow rate. Try inclining
the trench floor in a downstream direction, or lining the trench with smooth material
such as a plastic tarpaulin to reduce friction.
SYSTEM INSTALLATION
After locating a suitable site and completing the earthworks (if any), your PowerPal is
ready for installation. To do this:
1. Connect the water intake canal (A) to the water outlet pipe (B). Insert the rubber
seal (C) at the connection point. Bolt the canal and pipe together. Note that the
connections should be airtight or performance will be significantly reduced.

Canal and pipe connection should be airtight.
Simpler than a dam, it is most suitable
for small villages or isolated houses. It
also avoids the worst of flooding as
most of the stream flow will follow the
main stream channel.
