1. Green algae growth stimulation testing

Algal growth potential tests using the green algae Raphidocelis subcapitata (=Pseudokirchneriella subcapitata = Selenastrum capricornutum) were performed on ambient waters collected from 6 Idaho streams from September 7 to 21, 2007. Tests were conducted by a contract laboratory, GEI/Chadwick Ecological Division, Littleton, Colorado.

Microplastics in 29 Great Lakes tributaries (2014-15)

This dataset describes the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states. Samples were collected in spring 2014 – spring 2015. Each tributary was sampled three to four times, capturing low-flow and runoff-event conditions. Sampling and analysis methods are described in the .xml metadata file. These data are interpreted in a journal article %

Drought conditions during NHD topographic surveys and other streamflow observations in the Pacific Northwest, USA

This dataset adds attributes describing the self-calibrated Palmer Drought Severity Index (PDSI) during the observation year of wet/dry streamflow observations collected in the Pacific Northwest, USA. Streamflow observation locations are linked to the nearest National Hydrography Dataset high-resolution (NHD-HR) stream segment to obtain stream order and stream permanence (perennial%

Biogeochemical Data for Mercury and other Constituents in Surface Sediment and Deep Cores from the Hells Canyon Reservoir Complex, Idaho and Oregon 2014-2018

Due to concerns regarding mercury (Hg) contamination within the HCC, in cooperation with Idaho Power Company, the U.S. Geological Survey has been leading an investigation into the sources, transport, microbial transformations, chemical speciation and bioaccumulation of Hg in this complex river-reservoir environment.

Model Archive Summary for Suspended Sediment, Acoustic Sediment Surrogate Model 2.0, USGS gage number 13342500, Clearwater River at Spalding, Idaho

From 2008 to 2012, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, Walla Walla District, developed an acoustic backscatter surrogate (model 1.0) for estimating real-time suspended-sediment concentration and loads at Clearwater River at Spalding, ID (USGS ID: 13342500) using a horizontally-mounted 3000kHz acoustic Doppler velocity meter (ADVM

Hydrogeologic Framework of the Treasure Valley and Surrounding Area, Idaho and Oregon; Well Data

A three-dimensional hydrogeologic framework model (3D HFM) of the westernmost western Snake River Plain (WSRP) aquifer system was prepared to represent the subsurface distribution and thickness of four hydrogeologic units. The primary source of data for the 3D HFM was lithologic data from a total of 291 well-driller reports. These data were then processed using Rockware Rockworks17 three-

Kootenai River Habitat Restoration Project Bathymetric Surveys near Bonners Ferry, ID, Water Years 2009-2018

In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Koote
