SWIMMERS were left in amazement after a gigantic hole appeared in the middle of a U.S. lake. Onlookers questioned whether they had come across a supernatural whirlpool or a portal to hell as the mysterious hole appeared in Lake Berryessa, the seventh-largest manmade lake in California. However although looking like a natural phenomenon the giant hole is in fact a manmade spillway known as a “Glory Hole.” The tunnel is used to drain the lake to stop if from overflowing. In 1997 swimmer Emily Schwalek died after being pulled down the spillway. It was reported the 41-year-old was seen swimming towards the gaping hole and spent 20 minutes gripping onto the edge before dropping out of sight. Last year the Lake Berryessa reservoir reached full capacity for the first time in 11 years, causing widespread amazement. (SD-Agencies) |
