In 2005, the Asia Paranormal Investigators team led by Charles Goh came across an abandoned reservoir while they were searching for the lost tomb of a Japanese naval engineer at the foot of Mount Faber. Goh first believed that it was an abandoned swimming pool due to the remnants of a diving board and bathing area at that time. The site was not fenced and there was an old sign hanging from a tree that cautioned visitors not to swim or fish in the reservoir.
