Freshwater Found Miles Deep Under Great Salt Lake

Researchers used airborne electromagnetic surveys to map a freshwater reservoir extending 3 to 4 kilometers beneath Great Salt Lake, potentially aiding regional water management.

  • The Whiskey Island salt mine below Cleveland produces salt used for winter road maintenance across the Northeast and Great Lakes regions.
  • Cargill, owner of the mine, reports that early and harsh winter weather has increased demand, leading to overtime work since September.
  • Many municipalities have used up their usual salt supplies that typically last through the spring, according to Cargill spokesperson Emily Tangeman.
  • Despite high demand, the mine has enough salt reserves to continue operations for decades, producing 3 to 4 million tons annually, stated Campbell.
