Survey
Map the pond's full original area, its inlets and its catchment, and record encroachments and sewage outfalls.
The 1st Census of Water Bodies counted 55,734 water bodies in Kerala. 9,184 of them were not in use and 111 had been encroached upon. Pick a district below to see its ponds on a map, village by village.
9,184 of 55,734 water bodies (16%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Districts ranked by number of ponds. The bar shows ponds; the line under each name shows all water bodies and how many are not in use.
Ponds are one way rain gets back into the ground. See how hard Kerala is pumping its groundwater, district by district.
Most ponds that are not in use can be revived. The work is the same in a village or a city sector:
Map the pond's full original area, its inlets and its catchment, and record encroachments and sewage outfalls.
Dig out the silt that has sealed the bed, so water soaks into the ground again instead of evaporating.
Clear and line the channels that bring rain in, with a silt trap before the pond; divert sewage away from it.
Add recharge shafts or wells in the bed where the soil is tight, so water reaches the aquifer faster.
Fence or plant the banks, mark the boundary and hand upkeep to the panchayat or residents' body.
The 1st Census of Water Bodies (Ministry of Jal Shakti, counted in 2018-19, published 2023) counted 51,007 ponds in Kerala, out of 55,734 water bodies in all.
The 1st Census of Water Bodies counted 4 lakes and 63 reservoirs in Kerala, along with 848 tanks.
9,184 of the 55,734 water bodies (16%) were not in use when counted: dried up, silted, cut off from their catchment, polluted or built over. 111 had been encroached upon.
Palakkad, with 5,795 ponds and 5,988 water bodies in all, according to the 1st Census of Water Bodies.
A working pond holds rain long enough for it to soak into the ground and refill wells and borewells nearby. A silted or encroached pond sends that rain down the drain instead. Desilting, reopening inlets and adding recharge shafts in the pond bed are among the cheapest ways to recharge groundwater.
