Overview
- Instagram videos show unknown surfers placing a wooden ramp at night that briefly recreated a rideable wave before the structure was removed.
- Authorities stress that unauthorized riverbed modifications and night surfing are illegal, and surf groups call the ramp a short-term, unsanctioned workaround.
- Specialists from Helmut-Schmidt-Universität Hamburg conducted measurements, with preliminary analysis indicating a mix of reduced flow and a lowered riverbed is blocking wave formation.
- Municipal teams are testing water-supply adjustments and considering carefully managed gravel reintroduction, but no approved solution has been announced.
- The clandestine reactivation drew both praise and criticism, adding pressure on officials already exercising caution after an April fatality and restricted surfing hours.
