Upper Klamath Basin Groundwater Studies

Since the late 1990s the USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to help evaluate the state of the groundwater system and its response to external stresses, and to develop computer models to provide insights useful for water management. These efforts build on earlier USGS studies in the basin going back...

Reconstructing Flow History From Riparian Tree Rings

Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We also use downscaled climate...

Selenium in the Blackfoot River Watershed

The upper Blackfoot River receives runoff from 12 large phosphate mines. Shale waste rock that is a byproduct of mining is highly enriched in naturally occurring selenium. At optimal concentrations, selenium can be a positive nutrient and antioxidant in mammals and fish. At elevated concentrations, however, it can damage fish and animal immune systems. As early as 1996, livestock deaths...
