Below Mount Shasta, a Fight Burbles over Bottled Water

In an aquifer as convoluted as Shasta’s, it’s not easy to determine the effects of pumping groundwater or diverting springs for bottled water, says Gordon Grant, a hydrologist with the U.S. Forest Service’s Pacific Northwest Research Station. With most of the 80 inches of annual precipitation seeping underground, some estimates suggest as much as 40 million acre-feet may be stored in the complex volcanic fissures — more than California’s top 100 reservoirs combined.

More water in meadows unlikely to aid streamflows

“If they are looking to change the composition of the plant community or increase the frequency with which channels flood onto their floodplains, these strategies have a good chance of success,” said Nash. “But if the goal is to increase stream flow late into the summer, they'd be better off trying something else.”

Expert Q&A: Caroline Nash

"Just how much work can we expect beaver and their dams to do for us? And under what conditions? Geologist/hydrologist Caroline Nash is part of an interdisciplinary team whose work is helping to provide just such a reality check."

Earth’s skin is an interdisciplinary laboratory

Critical-zone science has come into its own, says Gordon Grant, a hydrologist and geomorphologist with the US Forest Service in Oregon and chair of the CZO scientific steering committee. “It lifts the hood on a previously cryptic environment, revealing things that seem paradoxical,” he says.

Legacy of the Mount St. Helens 1980 eruption still defies perfect solution

A new report (Grant et al., 2017) published this summer by the U.S. Forest Service (USFS) describes the complex and interrelated natural hazards—volcanic, seismic, and hydrologic—and risks associated with several options to manage the water level of Spirit Lake (https://www.fs.usda.gov/treesearch/pubs/54429). The USFS is the agency charged with management of the Mount St.
