Rapid City Journal : The water level at the Sanford Underground Laboratory at Homestake was down to 4,784 feet underground on Monday, only 66 feet above the important 4,850-foot level in the former gold mine.
The water level at Homestake is down 254 feet since the high-water mark was reached last August.
Homestake is 8,000 feet deep. Mining stopped in 2001, and the underground pumps were turned off just before Homestake was sealed shut in 2003. Water was slowly filling the mine until last year. Now, the South Dakota Science and Technology Authority is pumping water out to reopen Homestake as an underground laboratory, with experiments as deep as 4,850 feet underground
