A recent discovery in Oregon’s Cascade Range may have a significant impact on the area’s water resource management. Researchers from the University of Oregon who were examining an area where part of the Cascade Range meets Santiam Pass learned that an aquifer in the area is significantly larger than previously believed.

The aquifer holds more than 80 cubic kilometers of water, which is three times Lake Mead’s capacity. The discovery, however, does not make that amount of water instantly available.

“It is a big, active groundwater reservoir up there right now, but its longevity and resilience to change is set by the availability of recharging waters,” said Leif Karlstrom, a University of Oregon earth scientist who led the research.

Aquifers are permeable rocks where water can be stored underground. They can serve as underground reservoirs for groundwater. The water in aquifers can be pumped in or out when necessary. When the water in aquifers is depleted, like a cell phone battery, it can take a long time to recharge and may never regain its full capacity.

Many aquifers in the United States are seriously depleted, putting groundwater sources in danger. Conserving water can help keep groundwater sources, including aquifers, fully charged.
