Follow our live coverage for the latest news on the coronavirus pandemic. The massive Morning Glory Spillway in the Lake Berryessa reservoir in northern California was originally designed to funnel away water after unusually big storms, and was only expected to flow a couple of times per century when heavy rains filled the lake to capacity. But recent dramatic video and photographs show the circular spillway, known by locals more colourfully as the "glory hole", flowing for the second time in two years, after the brimming lake became too big for its banks. The compelling sight of the metre-wide, metre-long drain in full flow after record recent rains in the area is also reportedly inspiring locals to wax lyrical about what it reminds them of when the water's really pouring through it. According to the Guardian , some said water coursing through the spillway's "bell mouth" looked like a toilet being flushed. More generous descriptions were that it resembled a giant whirlpool or a beautiful inverted fountain in the lake, which is a popular haunt for boaters and swimmers.
Monticello Dam - Wikipedia
Record-breaking rainfall has caused water to flow into the manmade hole in Lake Berryessa 70 miles west of Sacramento for the first time in nearly a decade. Officially called the Monticello Dam Morning Glory Spillway, the hole is designed to keep the dam from overflowing. It works sort of like a sink drain. But instead of the drain being at the bottom of the lake, it sits at the top. When the water rises to a certain level it flows over the top and into the foot-wide, foot-long pipe into a river below.

The Glory Hole at Lake Berryessa
Monticello Dam is a foot 93 m high concrete arch dam in Napa County, California , United States , constructed between and Lake Berryessa is currently the seventh-largest man-made lake in California. Water from the reservoir primarily supplies agriculture in the Sacramento Valley downstream. The dam is noted for its classic, uncontrolled morning-glory-type spillway.
The California floods saw the Oroville dam overflowing , while elsewhere in California excess water became a sight not often seen in this arid part of the western United States. Two years later in February , after a series of storms hit northern California, the epic sight returned to Lake Berryessa. This singular drainage system shaped like a funnel is located in the Monticello Dam, built between and in the Berryessa Valley, in Napa Country.
