Beginning to worry about my "tick"
Maybe you can get it from somewhere else, namely Beijing! A fair few others on the forum may get this "tick" on the back of this as well.
• Part 22 (TH-01), Old Beijing City comprises: (1) an urban section of the canal (0.5 km), which is an archaeological site; (2) the upper lock of Chengqing; (3) the lower lock of Chengqing; (4) Shixha Lake
So I'm pretty confident it is this area here
. The southern lake is translated as Shicha(i) Lake so seems to be the one in question. There is also a lock on the Western side leading to 0.5km of dried canal bed (running along Dongbanqiao Rd/ Beihe Hutong). Perhaps more importantly this batch of lakes is identified
as the northern terminus of the Grand Canal.
From zooming in a lot on the map in p185 of ICOMOS evaluations
for this year puts it in that area as well. So I think we have a winner, also seems I was on the right lines with my snuffling out a pre-emptive visit
Shichai Lake and Hui Hai Lake link together there and are a pretty popular night spot (when I visited it felt like it was being developed as a sort of travellers hang out a la Khoa San Road
with a night market and lots of slightly soulless Western bars
being built or newly opened). It has also been famous for a fair while back for its restaurants selling Peking duck. It is also a short stroll from the Drum and Bell towers, and just north of the Forbidden City and Belhai park.
If all that is right and it gets inscribed we will also have a new connection of sites within walking distance: Temple of Heaven> Forbidden City> Grand Canal.
Hope that brings a few more to the visit counts of people :)
