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 2,701 ponds, tanks, lakes and other water bodies in Lohardaga district. 203 of them (8%) were not in use and 10 had been encroached upon. Lohardaga has the 17th most ponds of the 23 districts in Jharkhand the census counted.
203 of 2,701 water bodies (8%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Lohardaga pumps out 15% 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.

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, Lohardaga district pumped out 15% of the groundwater that can safely be taken out each year ("safe").
