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 1,941 ponds, tanks, lakes and other water bodies in Khunti district. 497 of them (26%) were not in use and 37 had been encroached upon. Khunti has the 19th most ponds of the 23 districts in Jharkhand the census counted.
497 of 1,941 water bodies (26%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Khunti pumps out 28% of the groundwater that can safely be taken out each year (2025, Central Ground Water Board), which the board rates safe. Working ponds are a large part of what keeps it there, by letting rain soak back into the ground.
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 1,740 ponds in Khunti district, out of 1,941 water bodies in all. That is the 19th most ponds of 23 districts in Jharkhand counted by the census.
The 1st Census of Water Bodies counted 12 lakes and 41 reservoirs in Khunti district, along with 54 tanks.
497 of the 1,941 water bodies (26%) were not in use when counted: dried up, silted, cut off from their catchment, polluted or built over. 37 had been encroached upon.
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.
In the 2025 Central Ground Water Board assessment, Khunti district pumped out 28% of the groundwater that can safely be taken out each year ("safe").
