Description

1. Ponds are usually located on land with a gentle slope. The vast majority of freshwater is raised in ponds. Water is taken from a lake, bay, well, or another natural source and is directed into the pond.
2. The water either passes through the pond once is discharged or it may be partially replaced so that a certain percentage of the total water in the system is retained and recirculated.
3. They are rectangular or square-shaped, have well-finished dikes and bottom slopes, and do not collect run-off water from the surrounding watershed. It is important that sufficient water is available to fill all ponds within a time and to maintain the same pond water level.

You should be able to drain the pond completely when the fish are to be harvested.
