Classification of ponds based on source of water

Diversion ponds
These ponds are made by bringing water (diverting) from another source like stream or river. Channels are dug to carry the water from the source to the pond.

Diversion ponds can be made in a number of ways. Sometimes a pond is dug in flat ground can be made by slightly enlarging a natural depression of the land. Number of ponds wall depending upon the topography of the land and the drainage system used. A pond dug in flat ground often requires four walls; a pond built in a natural depression may not. In these ponds the direct entry of water can be avoided.

When a series of diversion ponds is built, they are built in two ways.

• Rosary system
• Parallel system
