This data release pertains to a seepage investigation and dye tracing study conducted in the Big Creek watershed of Newton County, Arkansas. The seepage dataset includes geospatial files of discharge measurement points and zero-flow observations along with vector lines delineating losing and gaining stream reaches. The dye tracing dataset consists of geospatial files of monitoring sites, dye injection location, and dye flow paths. Hydrologic systems in karst environments have a high degree of interconnectivity between surface water and groundwater systems. Because of this interconnectivity, activities which occur on the surface in karst environments have a direct impact on the water quality and quantity of karst...

This is a geochemical data set from the reanalysis of 44 rock samples collected between 1966 and 1970, and 107 sediment samples collected in 1966 and 1967. These samples were collected by the U.S. Geological Survey for a study investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the Lower Middle Fork of the Salmon River, including the tributaries of Big Creek, Camas Creek, Brush Creek, Wilson Creek, Waterfall Creek, Ship Island Creek, Reese Creek, Stoddard Creek, and Papoose 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. Mary P. Rossillon (1981) explored...

Data describe a designed environmental DNA (eDNA) survey for the detection of longnose darter (Percina nasuta) in field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater fish species tissue samples that were used to test specificity of the assay; and field collected water samples that were tested to detect the presence of longnose darter DNA. Samples were collected from sites on the St. Francis river, Missouri in 2018.

This record documents the fields of datasets (which are contained in Microsoft Excel spreadsheets and MS Access databases) that describe upland, riparian, and stream ecosystems in the following areas: (1) Idaho - South Fork Salmon and East Fork South Fork Salmon River drainages following the 2000 Diamond Peak Fire, before and after the 2004 Parks-Eiguren Prescribed Fire, before and after the 2006 Williams and Fitsum Prescribed Fire, before and after the 2006 and 2007 South Fork Salmon Complexes, Krassel RD-Payette NF; (2) Montana – Bitterroot River following the 2000 Bitterroot Valley Fire Complex, Sula RD-Bitterroot NF; (3) Oregon - 2001 Quartz Fire, Applegate RD-Rogue NF; Grayback Mtn-Siskiyou NF; 2002 Biscuit...
Stream segments, aquatic organism captures, stream surveys, and road-stream crossings described by these metadata accompany a 2012 electrofishing study of the distribution and abundance of aquatic organisms (fish, lampreys, amphibians and crayfish), conducted by the U.S. Geological Survey, and the Pacific Northwest Region Aquatic and Riparian Ecosystem Monitoring Project (AREMP) of the U.S. Forest Service, in the Siuslaw National Forest in western Oregon, USA. The purpose of the study was to quantify the effectiveness of stream-road crossing restoration (culvert replacement to the stream simulation standard) in terms of numbers of fish and length of stream gained through restoration, and to quantify the continuing...

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.
