History
Flood of 1965
In July 1965 a devastating flood occurred, which became part of regional history as a once-in-a-hundred-years flooding and is remembered by locals as the "Heinrichsflut" (Henry's Day Flood). After heavy rainfalls from July 15 through to 17 (more than 135 L/m
2), basements were flooded. In the village of
Wewelsburg a bridge collapsed, an Army sapper unit had to be brought in for disaster relief. Streets turned into river beds, railway and bus traffic had to be stopped, 16 people died. As a consequence of the flood, which also took in the tributaries of the Alme and the Lippe river itself, the "
Wasserverband Obere Lippe" (board for basin management of the upper Lippe river) was founded, one of whose aims is to prevent or mitigate any damage that may be caused by further floods mainly by way of building
detention basins.
Flood of 2007

On August 22, 2007, the Alme river burst its banks around the town of
Büren, after heavy rainfalls of some 70 L/m
2 in the course of one night. In the village of Weine the flood level exceeded that of 1965. Even though the flood was less sweeping in effect than the "Heinrichsflut",
[see paragraph above or entry "Heinrichsflut" on German Wikipedia] schools in Büren had to finish early and send the pupils home, some streets became impassable. 220 local firefighters supported by emergency response units of
THW,
DLRG and
DRK were deployed to clear out flooded basements or to protect houses in low grounds by stacked
sandbags.
