More than four-fifths of shallow groundwater monitoring sites and springs in Bavaria recorded low or very low water levels on 21 August, underscoring how recent rainfall has done little to replenish depleted aquifers. The current 81 percent figure marks a sharp deterioration from the same period in 2021, when only 19 percent of sites were affected, though it exceeds the 66 percent recorded during the severe drought year of 2022.
Persistent heat has compounded the strain. The town of Kitzingen in Lower Franconia has logged 51 days with temperatures reaching 30 degrees Celsius or above this year, while Hof in Upper Franconia recorded 18 such days.
On major waterways, Rhine levels have risen modestly, approaching normal flow at Maxau and climbing toward 80 centimetres in Rhineland-Palatinate. Yet the Federal Institute of Hydrology' six-week forecast indicates no meaningful relief on inland waterways before early October.
