The 2026 heatwave that pushed temperatures above 40 °C across Germany, Belgium, the Netherlands and neighboring regions continued into late July, prompting stricter water‑conservation rules. German states widened bans on private water extraction for irrigation and other uses, with fines up to €50,000; the Dutch kept the Eefde sluices closed and urged residents to curb consumption. On 26 July Brandenburg an der Havel prohibited extraction of water from rivers, lakes, ponds and ditches for private use until 31 August, limiting garden irrigation to night hours and banning pool‑filling, with penalties of up to €50,000. The Main‑Spessart district followed suit on 24 July, issuing an Allgemeinverfügung that bans water take‑out from surface water bodies of order II and III while exempting the Main River.

The municipality of Amersfoort extended its free garden‑water‑advice programme to Hoogland, promoting rain barrels and permeable paving as drought persists. A water‑deficit of roughly 25 mm in the Groene Hart prompted warnings that livestock‑farm irrigation bans could follow, while Boskoop greenhouse growers face the prospect of using more saline water. In Germany, the town of Schönwald now relies on deep wells and urges leak‑fixes, rain‑water garden use and limits on pool filling. Near Koblenz, Rhine water temperatures hit 28 °C, surpassing the 25 °C barbel‑fish threshold and lowering oxygen levels; a passenger hotel ship recently ran aground. Austria’s Horn town began replacing up to 1,000 overdue water meters, a costly effort triggered by backlogs. River inflows at the Lobith gauge fell to a historic 715 m³/s, prompting a Level 2 water crisis on 25 July. Alpine glacier melt was cited as a key cause. The Rhine reached historic lows—40 cm in Düsseldorf and stagnant flow in Cologne—leading to navigation limits and grounding incidents. Fire risk stayed high, with field fires in North‑Rhine‑Westphalia and Saxony‑Anhalt damaging hundreds of hectares. The drought also deepened deficits in Swiss lakes, Greek Aegean islands and Norwegian groundwater, underscoring the broad, multi‑country impact of the prolonged Central European heatwave.
