Researchers in Oregon have discovered a massive water reservoir beneath the Central Oregon Cascades, estimated to be three times the capacity of Lake Mead. The aquifer, described as a “body of rock and/or sediment that holds groundwater,” totals at least 81 cubic kilometers.
The study, published in the Proceedings of the National Academy of Sciences, involved collaboration between the University of Oregon, Oregon State University, the U.S. Forest Service, and other agencies. According to Leif Karlstrom, an earth scientist at the University of Oregon, the newly discovered aquifer could indicate a larger reservoir in the area.
“It’s like a big water tower,” Karlstrom said. “The Cascade Range is likely the largest aquifer of its kind in the world.” However, scientists warn that the size of the aquifer depends on snowpack, which is projected to decline significantly within several decades.
“This affects us when we don’t have any snow or get a run of bad winters,” USFS Geologist Gordon Grant said. “Those are the key questions we’re now having to focus on.” The discovery highlights the connection between water movement and volcanic activity, underscoring the importance of understanding the region’s geological dynamics.
