In Lower Saxony groundwater remains at a very low level for the time of year in many parts of Lower Saxony. According to a report by NDR on 12 November 2026, the Lower Saxony Water Management, Coastal Defence and Nature Conservation Agency has so far seen no recovery. Data from the state confirm the difficult situation at some monitoring stations. They also show how carefully the figures need to be interpreted.
Citing the agency, NDR reports that levels were very low at 76 of 161 monitoring stations, while a previous record low was breached at a further 39. The agency recorded stable or still-falling levels. Its publicly available station data are labelled as unchecked raw data.
One example is the monitoring station at Schweringen I in Nienburg district. On 11 November 2026, the agency classified the level there as “below the lowest recorded value”. At the Ohr 1 monitoring station in Hameln-Pyrmont district the classification also showed that the lowest recorded value had been breached on that day. At Bakede II in the same district, the level was rated as very low.
The classification applies to the individual location and its seasonal comparison series. According to the agency, current readings are compared with statistical thresholds calculated for each month using long-term measurement series. The reference period is generally 1991 to 2020. A low reading therefore does not necessarily mean that the absolute lowest level since measurements began has been reached at every location.
Low groundwater levels are not unusual in autumn: supplies need time to replenish after the warm season. However, according to the NDR report, the agency has seen extreme situations more frequently in recent years and points to climate change. Water use also plays a role alongside weather conditions. Drinking water supplies, agriculture and industry all depend on available resources.
The effects vary by location. Low groundwater levels can also have an impact on bodies of water. Prolonged water shortages are a stress factor for forests: according to Lower Saxony State Forests they can affect tree vitality and growth. However, current groundwater levels alone do not point to widespread tree deaths in the immediate future, a spokesperson told NDR.
Recovery depends on more than a few days of rain. Water has to seep into the ground and replenish groundwater supplies. How quickly this happens depends, among other things, on local conditions and further rainfall. The monitoring data provide a picture of how levels are changing; according to the agency, they do not in themselves determine whether water may be abstracted.
