Why Lohit's ponds matter for its groundwater
0.4%Safe
Lohit pumps out 0.4% of the groundwater that can safely be taken out each year (2023, 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.
Bringing a pond in Lohit back
Most ponds that are not in use can be revived. The work is the same in a village or a city sector:
Desilt
Dig out the silt that has sealed the bed, so water soaks into the ground again instead of evaporating.
Reconnect
Clear and line the channels that bring rain in, with a silt trap before the pond; divert sewage away from it.
Recharge
Add recharge shafts or wells in the bed where the soil is tight, so water reaches the aquifer faster.
Protect
Fence or plant the banks, mark the boundary and hand upkeep to the panchayat or residents' body.
