Historical development of the U.S. Geological Survey hydrological monitoring and investigative programs at the Idaho National Laboratory, Idaho, 2002–2020

This report summarizes the historical development and operations, from 2002 to 2020, of the U.S. Geological Survey’s (USGS) hydrologic monitoring and investigative programs at the Idaho National Laboratory in cooperation with the U.S. Department of Energy. The report covers the USGS’s programs for water-level monitoring, water-quality sampling, geochemical studies, geophysical logging, geologic fr

Precision of headwater stream permanence estimates from a monthly water balance model in the Pacific Northwest, USA

Stream permanence classifications (i.e., perennial, intermittent, ephemeral) are a primary consideration to determine stream regulatory status in the United States (U.S.) and are an important indicator of environmental conditions and biodiversity. However, at present, no models or products adequately describe surface water presence for regulatory determinations. We modified the Thornthwaite monthl

Risk-based prioritization of organic chemicals and locations of ecological concern in sediment from Great Lakes tributaries

With improved analytical techniques, environmental monitoring studies are increasingly able to report the occurrence of tens or hundreds of chemicals per site, making it difficult to identify the most relevant chemicals from a biological standpoint. For this study, organic chemical occurrence was examined, individually and as mixtures, in the context of potential biological effects. Sediment was c

USGS bathymetric survey vessel on Lucky Peak Lake, southwestern Idaho

Bathymetric Survey of the Mores Creek Arm of Lucky Peak Lake

In 2004, about 90 migrating elk and 25 mule deer broke through thin ice and drowned as they attempted to cross the Mores Creek arm of Lucky Peak Lake upstream of the Highway 21 bridge. To prevent any similar incidents, reservoir managers and wildlife biologists needed a better understanding of water depths over a range of reservoir pool elevations.

American Falls Reservoir Bathymetry

In cooperation with the Bureau of Reclamation, we surveyed the bathymetry within an area of about 500 acres of American Falls Reservoir between River Miles 713 and 714 August 6-8, 2019. The bathymetric survey provided high-resolution detail of a proposed treatment area for an aeration system that is being developed to support water quality during the American Falls spillway concrete repair project...

Continuous Water-Quality Monitoring of Middle Snake River Springs in Support of Threatened and Endangered Snail Species

Two species of aquatic snails, the Banbury Springs limpet (Idaholanx fresti) and the Bliss Rapids snail (Taylorconcha serpenticola) live in springs along the middle Snake River in south-central Idaho. The U.S. Fish and Wildlife Service has listed these species as Endangered (Banbury Springs limpet) and Threatened (Bliss Rapids snail). Both species need clean, cold spring water to survive.
