Switch thirsty crops, water by drip
Where most water goes to fields, moving from paddy and sugarcane to millets, pulses or maize, and from flood to drip or sprinkler irrigation, saves more than any recharge can add.
Groundwater level in Goalpara
33%Safe
Groundwater use is within safe limits here. That is the 2025 stage of groundwater extraction: water pumped out in a year as a share of what rain and other sources safely put back. Up 18 points since 2017.

Each point is one CGWB assessment. Over-exploited means more water leaves the ground than comes back, so the water table keeps falling. Hover over or tap a point to see why it moved.

| Year | Stage | Pumped out | Safe limit | Category | What changed |
|---|---|---|---|---|---|
| 2009 | 26.0% | 266 million m³ | 1.0 billion m³ | Safe | First assessment in this series. |
| 2013 | 12.0% | 128 million m³ | 1.1 billion m³ | Safe | Pumping down 52% (266 → 128 million m³). Safe limit up 8% (1.0 → 1.1 billion m³). Main reason: less water was pumped out, mostly for irrigation (244 → 105 million m³). A swing this large usually comes partly from revised estimates (a new well count or changed district boundaries), not only from changes on the ground. |
| 2017 | 14.5% | 122 million m³ | 839 million m³ | Safe | Pumping down 5% (128 → 122 million m³). Safe limit down 23% (1.1 → 0.8 billion m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 18.5% | 119 million m³ | 645 million m³ | Safe | Pumping down 2% (122 → 119 million m³). Safe limit down 23% (839 → 645 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2022 | 20.8% | 124 million m³ | 595 million m³ | Safe | Pumping up 4% (119 → 124 million m³). Safe limit down 8% (645 → 595 million m³). |
| 2023 | 21.2% | 124 million m³ | 587 million m³ | Safe | Pumping up 0% (124 → 124 million m³). Safe limit down 1% (595 → 587 million m³). |
| 2024 | 21.3% | 125 million m³ | 584 million m³ | Safe | Pumping up 0% (124 → 125 million m³). Safe limit down 0% (587 → 584 million m³). |
| 2025 | 32.7% | 174 million m³ | 532 million m³ | Safe | Pumping up 39% (125 → 174 million m³). Safe limit down 9% (584 → 532 million m³). Main reason: more water was pumped out, mostly for irrigation (100 → 148 million m³). A swing this large usually comes partly from revised estimates (a new well count or changed district boundaries), not only from changes on the ground. |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

Ponds and lakes in Goalpara
120 of 9,007 water bodies (1%) are not in use: dried up, silted, built over or polluted. Bringing them back is one of the cheapest ways to recharge groundwater.

What will fix it here
Groundwater here is in balance. Keeping it that way means recharging as the area builds up and paves over.
Revive village ponds and johads
Desilting old ponds and opening their feeder channels restores natural recharge. A one-hectare pond that soaks in a metre of water over the monsoon puts back about a crore litres.
Rooftop rainwater recharge
Pipe roof water through a silt trap and filter into a recharge pit or an old borewell. Every 100 m² of roof puts back tens of thousands of litres a year, right where the pumping happens.
Recharge pits and shafts in open land
Parks, campuses, warehouse yards and road sides can take recharge shafts that reach past the clay layer, so runoff that floods streets goes down to the aquifer instead.
Check dams and contour trenches
On sloping or rocky land, small dams on seasonal streams and trenches along contours slow water down long enough for it to sink in.
Treat and reuse wastewater
Treated water from a sewage treatment plant can run flushing, gardens, cooling towers and construction, which today often draw on borewells.
Frequently asked questions
What is the groundwater level in Goalpara?
In the 2025 Central Ground Water Board assessment, Goalpara (Assam) pumped out 33% of the groundwater that can be safely taken out each year, which puts it in the "safe" category. That is 18 points higher than in 2017.
Is groundwater in Goalpara over-exploited?
No. At 33% of the safe yield, Goalpara is safe, though recharge is still needed as demand grows.
How can groundwater be recharged in Goalpara?
Rooftop rainwater harvesting into recharge pits or old borewells, recharge shafts in open land, reviving ponds, check dams, treating and reusing wastewater, and moving farms to drip irrigation and less thirsty crops.
How many ponds and lakes are there in Goalpara?
The first Census of Water Bodies counted 9,007 water bodies in Goalpara, including 8,867 ponds. 120 of them were not in use.
