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 4,680 ponds, tanks, lakes and other water bodies in Lucknow district. 954 of them (20%) were not in use and 493 had been encroached upon. Lucknow has the 17th most ponds of the 75 districts in Uttar Pradesh the census counted.
954 of 4,680 water bodies (20%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

Lucknow pumps out 68% 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 4,662 ponds in Lucknow district, out of 4,680 water bodies in all. That is the 17th most ponds of 75 districts in Uttar Pradesh counted by the census.
The 1st Census of Water Bodies counted 3 lakes and 1 reservoir in Lucknow district, along with 9 tanks.
954 of the 4,680 water bodies (20%) were not in use when counted: dried up, silted, cut off from their catchment, polluted or built over. 493 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, Lucknow district pumped out 68% of the groundwater that can safely be taken out each year ("safe").
