Selenium and mercury in the Kootenai River, Montana and Idaho, 2018-2019

Selenium loads have been increasing over time in the Elk River, British Columbia, Canada, due to coal mining operations and runoff from associate spoil piles. The Elk River is a tributary to the Kootenay/Kootenai River and Lake Koocanusa. Extensive fish tissue monitoring has been conducted in Lake Koocanusa to assess the potential impacts of selenium from the Elk River (http://deq.mt.gov/DEQAdmin/

Point-Source Nutrient Loads to Streams of the Conterminous United States, 2012

The U.S. Geological Survey (USGS) developed a spatial water-quality model called SPAtially Referenced Regressions On Watershed attributes (SPARROW) to estimate the major sources and environmental factors that affect the long-term supply, transport, and fate of contaminants in the Nation's streams. The SPARROW model relates in-stream water-quality data to spatially referenced characteristics of wat

Compiled Database and Results of the Analysis of Multiple Groundwater-Quality Datasets for Idaho

Groundwater is an important source of drinking and irrigation water throughout Idaho, and groundwater quality is monitored by various Federal, State, and local agencies. The historical, multi-agency records of groundwater quality include a valuable dataset that has yet to be compiled or analyzed on a statewide level. The purpose of this study is to combine groundwater-quality data from multiple so

Treasure Valley Drains

To begin filling data gaps for development of a Treasure Valley groundwater-flow model, we installed 10 new real-time streamgages on drains along the lower Boise River from Eagle to Parma. The streamgages will monitor the amount of shallow groundwater the aquifer system discharges to surface water. This was a missing component in previously developed models.

Bridge Scour Countermeasure Assessment Data for Select Bridges in the United States

Scouring of streambed material surrounding bridge structures is a leading cause of bridge failure in the United States. Damages resulting from bridge failure oftentimes lead to financial burdens and loss of life. To date, there has been no comprehensive evaluation of the current (2016) effectiveness of the guidance or overall long-term performance of bridge-scour countermeasures provided in the Fe

Data release for microplastics in water, sediment, fish, and mussels in the St. Croix National Scenic Riverway and Mississippi National River and Recreation Area, Wisconsin and Minnesota, 2015

This dataset describes the concentration and morphology of microplastics in the St. Croix National Scenic Riverway and Mississippi National River and Recreation Area, Wisconsin and Minnesota. Samples were collected during baseflow conditions at eight locations during the week of August 3-7, 2015. Four types of samples were collected: water surface, streambed sediment, smallmouth bass (Micropterus
