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 1,377 ponds, tanks, lakes and other water bodies in Jalpaiguri district. 292 of them (21%) were not in use and 0 had been encroached upon. Jalpaiguri has the 19th most ponds of the 21 districts in West Bengal the census counted.
292 of 1,377 water bodies (21%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Jalpaiguri pumps out 12% 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 1,330 ponds in Jalpaiguri district, out of 1,377 water bodies in all. That is the 19th most ponds of 21 districts in West Bengal counted by the census.
The 1st Census of Water Bodies counted 9 lakes and 6 reservoirs in Jalpaiguri district, along with 15 tanks.
292 of the 1,377 water bodies (21%) were not in use when counted: dried up, silted, cut off from their catchment, polluted or built over. 0 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, Jalpaiguri district pumped out 12% of the groundwater that can safely be taken out each year ("safe").
