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...

Identifying Bull Trout Migration in the Upper Boise River Basin

In 1999, the U.S. Fish and Wildlife Service (FWS) listed the bull trout (Salvelinus confluentus) as a threatened species. In 2010, the FWS designated critical habitat for the bull trout, including the upper Boise River basin. The Bureau of Reclamation (Reclamation) operates three reservoirs on the upper Boise River for irrigation and flood control. Reclamation and FWS have a need to understand...

Occurrence and Potential Risk of Microplastics in Lake Mead and the Delaware River

There is mounting evidence that microplastics present a significant threat to aquatic organisms.
