When the Wetlooker.com site was rebuilt in 2019 a number of earlier sets had to be withdrawn for technical reasons.
This set was by way of a preview of the forthcoming Amateur section when it was posted on the main site in May 2016, the separate amateur section being launched later that year. Along with the now-deleted set vo-g3 which followed, these were shot around the same time as amateur sets in the series starting at c249 and which are still available.
The location is a flooded quarry, on the edge of Nikopol (Ukraine). This city has been a notable "wetlook hotspot" (wetspot?) for a few years now.
