Finger ponds use innovative techniques to enhance the natural productivity of wetlands and floodplains. The ponds (body of water smaller than a lake) consist of stretched artificial ponds 5 to 12 m long, extending into the wetland like fingers, hence the name. Finger ponds are excavated at the upstream edge of naturally occurring wetlands or floodplains and are lined with PVC plastic to prevent the water running out. They fill up during the flood cycle, and trap fish within them as the flooding recedes.
