Near-record ⁠low water levels on the Danube River have disrupted tourism this week, leaving cruise vessels stranded north of ​Budapest, suspending sightseeing trips and dealing a ​blow ⁠to the economically important sector.

Data from Hungary's Water Authority showed the Danube's water level in Budapest fell on Thursday morning to within 8 centimeters (3.15 inches) of the record low set eight years ago, although levels are expected to rise next week.

Hungarian sightseeing operator MAHART-PassNave said the decline was part of a longer-term trend and that, despite efforts by shipping companies and ports to adapt, water levels were increasingly falling ⁠below ⁠operational limits.

"River cruise vessels are currently still able to enter Hungary, but several ships are stranded or waiting in ports because of the low water levels," MAHART-PassNave Chief Executive Laszlo Somodi said late Wednesday.

Somodi said international river cruises had become by far the most economically important segment of Hungary's shipping industry as tourism expanded, carrying about ⁠600,000 passengers annually and generating wider economic benefits.
