A BETTER INLET
(91) You can also build a sluice in the trench to control the flow
of water into the pond.
(92) This sluice has a wall on each side of the trench
and a floor set into the bottom of the trench. There are slots in
the walls to hold wooden boards or a screen.
(93) Boards are put into the slots to keep water out
of the pond or taken out to let water in. When you are filling the
pond, put in a screen to keep out wild fish.
(94) You can build a sluice from wood, or if you know
how to build with bricks or blocks, you can use these.
(95) The drawings below show you how to build an inlet sluice using
wood.
