A staff member, identified as Li, told Beijing Youth Daily newspaper that they had hired a professional cleaning company and brought in 180 garbage collectors to keep the lake and its vicinity neat and tidy.
The sheer amount of sightseers, many with the habit of littering, compromised the cleaning efforts, despite shifts lasting up to 16 hours a day.
The management of the tourist spot has been broadcasting via loudspeakers announcements reminding tourists to dispose of their trash in designated areas.
The video was widely shared on Chinese social media, with netizens expressing shock at the situation.
"As a local, I really cannot bear this. The Caka Salt Lake, which has been known as 'the mirror of the sky; for years, is now a sewage ditch and has been polluted," a Weibo user who goes by the name @-Zst-dophinDaaijiege bemoaned.
