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 Davanagere
89%Semi-critical
Groundwater is under pressure 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. Down 4 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 | 90.0% | 500 million m³ | 557 million m³ | Semi-critical | First assessment in this series. |
| 2013 | 91.0% | 516 million m³ | 567 million m³ | Critical | Pumping up 3% (500 → 516 million m³). Safe limit up 2% (557 → 567 million m³). |
| 2017 | 93.0% | 614 million m³ | 661 million m³ | Critical | Pumping up 19% (516 → 614 million m³). Safe limit up 16% (567 → 661 million m³). CGWB changed its method in 2017 (GEC-97 to GEC-2015), so part of this change comes from the new method. |
| 2020 | 81.8% | 462 million m³ | 565 million m³ | Semi-critical | Pumping down 25% (614 → 462 million m³). Safe limit down 15% (661 → 565 million m³). Main reason: less water was pumped out, mostly for irrigation (582 → 435 million m³). |
| 2022 | 96.8% | 499 million m³ | 515 million m³ | Critical | Pumping up 8% (462 → 499 million m³). Safe limit down 9% (565 → 515 million m³). Main reason: less water soaked back in, from weaker rain, less canal seepage or more paved ground. |
| 2023 | 88.9% | 501 million m³ | 564 million m³ | Semi-critical | Pumping up 0% (499 → 501 million m³). Safe limit up 9% (515 → 564 million m³). Main reason: more water soaked back into the ground, from better rain, canals or recharge structures. |
| 2024 | 90.7% | 502 million m³ | 554 million m³ | Critical | Pumping up 0% (501 → 502 million m³). Safe limit down 2% (564 → 554 million m³). |
| 2025 | 88.6% | 512 million m³ | 578 million m³ | Semi-critical | Pumping up 2% (502 → 512 million m³). Safe limit up 4% (554 → 578 million m³). |
Million m³: 1 million m³ = 100 crore litres. 2009 and 2013 used the older GEC-97 method.

Ponds and lakes in Davanagere
374 of 387 water bodies (97%) 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
Most of the water here goes to farming, so using less on fields matters as much as recharge.
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 Davanagere?
In the 2025 Central Ground Water Board assessment, Davanagere (Karnataka) pumped out 89% of the groundwater that can be safely taken out each year, which puts it in the "semi-critical" category. That is 4 points lower than in 2017.
Is groundwater in Davanagere over-exploited?
No. At 89% of the safe yield, Davanagere is semi-critical, though recharge is still needed as demand grows.
How can groundwater be recharged in Davanagere?
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 Davanagere?
The first Census of Water Bodies counted 387 water bodies in Davanagere, including 25 ponds. 374 of them were not in use.
