Ghost lake set to reappear as California hit again by rain

LOS ANGELES - A lake that dried up 80 years ago looked set to reappear as monster rainfall accumulated over California's wet winter season overwhelms the state's rivers.

Even as spring appeared in the northern hemisphere, there was no let-up for America's most populous state, with forecasters predicting another 10cm of rain and up to 120cm of snow over the mountains.

"Another significant event... on top of everything that has come before is going to cause some major problems," meteorologist Daniel Swain said on Twitter. 

In California's Central Valley, authorities issued evacuation orders for residents of communities in Tulare County, where a lake that dried up around World War II was set to reappear.

"Increasingly serious high water prospects in what is shaping up to possibly be a record Kings River runoff season have led the US Army Corps of Engineers (USACE) Sacramento District to announce plans to begin a rare flood release into old Tulare Lakebed," said a statement from the King's River Conservation District (KRCD).

"Releases growing to 1,500 cubic feet per second... will begin taking the flood flows to the former lakebed in Kings County. 

"They are anticipated to continue indefinitely, USACE officials said, possibly lasting until sometime in the summer."

Tulare Lake was once the largest freshwater lake in the western United States, fed chiefly by snowmelt from the Sierra Nevada range.

But as the area was developed for agriculture and rivers were diverted for irrigation, the lake shrank, and by the middle of the 20th century, it had become farmland. 

It has flooded periodically since, including in 1983 when record snowfall covered the mountains, with 2023 shaping up to rival those totals.

Calling it "the winter that just doesn't want to end," the National Weather Service (NWS) in Reno, on the eastern side of the Sierra, said Tuesday this year is the second snowiest season in 77 years.

The western United States has been pummeled by a train of atmospheric rivers -- moisture-laden ribbons that ferry water from the Pacific over land.
