This data release includes sampling location data; field-collected stream attribute data; laboratory-analyzed chemistry concentrations (total mercury, methyl mercury) and isotopic composition (total mercury, carbon, and nitrogen) for stream biota (seston, periphyton, benthic insects, emerging adult insects, riparian spiders, and fish); density, body length, and taxonomic information for benthic insects; and density, biomass, and taxonomic information for emerging adult aquatic insects for biota sampled from stream reaches up and downstream of an historical mercury mine site. Sampling took place during summer low-flow conditions in 2015 and 2016. Stream reaches were located on USFS land near the Cinnabar Mine Site...

This USGS data release evaluates the impact of historical mining sites on water quality using samples collected in late July 2021 from Big Creek tributaries Coin Creek, Smith Creek, and Monumental Creek in Valley County, Idaho. These data were collected to support a fisheries mining impact assessment in the Middle Fork Salmon River. Specific conductance, pH, and stream temperature were measured in the field. Analyses include major cations and anions, alkalinity, trace metals, total mercury, and methylmercury.

This data release is a geochemical data set from the reanalysis of 23 rock and 85 sediment samples collected between 1966 and 1970 by the U.S. Geological Survey (USGS) for a series of studies investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the upper Middle Fork Salmon River and the South Fork Salmon River, including the tributaries of East Fork of the South Fork and Porphyry Creek. The overall objective of this study is to characterize the regional impact of legacy mining for the Frank Church - River of No Return Wilderness Area. In 1980 the U. S. Congress passed the Central Idaho Wilderness Act which combined the Idaho Primitive Area, the Salmon Rivers...

The development of a reliable method of age estimation for Grass Carp is necessary for the successful management of this invasive species. Multiple federal and state agencies with assistance from commercial fishers collected adult Grass Carp from 2012 to 2018. Ossified parts were collected from these fish, and age estimates from them were compared to develop an age estimation method. Here we provide the data used in that effort.

This U.S. Geological Survey (USGS) data release is an assessment of aquatic habitat within the tributaries of the lower Middle Fork Salmon River. These datasets are primarily focused on physical stream habitat (2020-21 stream temperature data) and the presence or absence (2021 eDNA data) of fish that inhabit the basin. Many environmental stressors contribute to the declining range and density of Bull trout (S. confluentus) populations, one of which is the toxic trace metals contributions from legacy mine waste and adits. These data were collected in stream habitats with variable physical and thermal conditions. Characterizing and comparing reference streams of similar physical attributes will assist to differentiate...

Water and sediment samples were collected by the U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency at or near baseflow conditions from 2015-2017 in the East Fork South Fork Salmon River watershed near Yellow Pine, Valley County, Idaho. Soil, rock and tailings samples were collected in June 2015. Sampling focused on Cinnabar Creek, which flows through the Cinnabar mine site, and Sugar Creek, with additional sites selected to place the data into a larger watershed context. Grab samples were taken of the snowpack in January 2017. The water, soil, sediment, and rock samples were as described and the results are presented as separate water and solid data sets.

This data set summarizes electrofishing effort, observations, and tissue sampling of aquatic vertebrates near Yellow Pine, Idaho. Sampling was conducted using a backpack electrofishing unit at two reference sites including Cane Creek and Sugar Creek, and at three mine impact sites including Sugar Creek and Cinnabar Creek. Juvenile Bull Trout (Salvelinus confluentus) were present at all five sites and were the primary species targeted during our sampling effort. Additional tissue samples of Sculpin, and amphibians were taken when available. Where possible, a two pass (quantitative depletion) electrofishing survey was conducted at each site for non-USGS stakeholders (Nez Perce Tribe and Idaho Department of Fish and...

The USGS examined mercury (Hg) concentrations in fish populations inhabiting impacted and reference streams as part of an investigation into the transport of trace metals in a watershed impacted by legacy mercury mining downstream from the Cinnabar mine site, Valley County, ID. Fish were sampled through an electrofishing survey utilizing a two-pass quantitative depletion approach where possible. Five reaches were selected in the Sugar Creek/Cinnabar Creek watershed, including two background reaches (ID020; ID021) with negligible mining impacts, Cinnabar Creek above the confluence with Sugar Creek (ID019), and two sites on Sugar Creek below the confluence with Cinnabar Creek (ID018 and ID010). Juvenile Bull trout...
