Wood River Valley Aquatic Biology and Habitat Assessment

Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...

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. Microplastics – defined as plastic particles less than 5 mm in diameter – come from many different sources, including synthetic textiles, industrial waste products, personal care products, and the breakdown of litter, car tires, and other objects. This study will assess the occurrence of...

Tritium deposition in precipitation in the United States, 1953–2012

Tritium is a radioactive isotope of hydrogen (half-life is equal to 12.32 years). Since it is part of the water molecule, tritium can be used to track and date groundwater and surface water when the history of tritium in precipitation and recharge is known. To facilitate that effort, tritium concentrations in precipitation were reconstructed from...
