 A mysterious occurrence at a lock in Scotland has left residents and archaeologists mystified. An ancient sites not seen by humans for 750 years have been revealed. Described as being a threat to Scottish heritage, according to the independent water levels in a freshwater Scottish lock, mysteriously reached a 750 year low earlier this year. According to archaeologists, studying the remains of an ancient settlement on a man-made island. Researchers at Lake Vaugh in the Cangorns collected and carbon-dated timbers which had been covered by water since the 13th century to reveal the water levels reached a historic low in May 2019. However, what remains unclear is what caused the lock to drain. It is a spring-fed lock with no other major water inlets or outlets. In May the water levels had fallen by 1.4 meters. It was like someone had pulled a plug, according to locals, and took until July for the lock to regain its usual level. According to researchers, the radio carbon dating we took came from a timber that was just about 15 centimeters below where the water level was in May. So what that says to me is that sometime in the last 750 years, the level had dropped to maybe as low as that point before, but no lower. Locals have previously blamed Scottish water, suggesting boreholes have drained the aquifers supplying the lock. But this has been rejected by the company, which said their activities three miles upstream were too far away to affect it. The Scottish Environment Protection Agency has suggested the lock had suffered due to a relatively dry winter. Whatever is going on, it is weird and nobody seems to know. Maybe a dry winter in 2018 followed by a summer heatwave of 2018 in the UK are to blame, but then again, maybe not.
