Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data from mesocosm experiments to assess metal and nutrient stimulation of Lake Erie and Lake Michigan phytoplankton communities, August 2017 Data from mesocosm experiments to assess metal and nutrient stimulation of Lake Erie and Lake Michigan phytoplankton communities, August 2017
To address how phytoplankton in the Great Lakes respond to macro- and micronutrients, we conducted a bottle incubation enrichment experiment using water collected from blooming (Maumee Bay and Fox River) and non-blooming sites (Detroit River and Ford River) in Lakes Erie and Michigan, respectively, during late summer. Surface water from these locations was collected and taken to Kent...
Digitized sonic velocity and density log data of the Eel River area, northern California Digitized sonic velocity and density log data of the Eel River area, northern California
Sonic velocity and density well logs in the Eel River area in northern California (Ferndale north Arcata) were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website (https://maps.conservation.ca.gov/doggr/wellfinder/). The data consist of transit times and bulk density measured downhole in...
Data for dam passage analysis of Silver Carp at three locks and dams on the Tennessee and Cumberland rivers from 2016–2019 Data for dam passage analysis of Silver Carp at three locks and dams on the Tennessee and Cumberland rivers from 2016–2019
Acoustic telemetry data (Innovasea, Inc.) were collected on invasive Silver Carp (Hypophthalmichthys molitrix) in the lower reaches of the Tennessee and Cumberland river systems to determine timing and environmental conditions associated with dam passages by Silver Carp during 2016–2019. Data also include water level. dam discharge, and lock use data for three dams within these river...
University of Wyoming Prairie & Desert Stream Fisheries Surveys, 2021-2024 University of Wyoming Prairie & Desert Stream Fisheries Surveys, 2021-2024
This dataset contains the accumulated stream survey data collected to identify climate impacts to fish communities and assess stream restoration as a potential climate-change mitigation action across the Great Plains and High Desert of Wyoming and Montana (2021-2024). We also provide data of incidental observations of amphibians, reptiles, crayfishes, and mussels seen while conducting...
Upper Colorado River Basin: Monitoring sites and water chemistry data used to develop a specific conductance - salinity proxy model Upper Colorado River Basin: Monitoring sites and water chemistry data used to develop a specific conductance - salinity proxy model
Salinity levels in streams and tributaries of the Colorado River Basin have been a major concern for years. Recently, the United States Geological Survey’s (USGS) Next Generation Water Observing System (NGWOS) program expanded stream monitoring networks including the number of sites where continuous (15-minute) specific conductance is measured in the Colorado River Headwaters and...
Temperature, soil property, and floodplain infiltration data from a restored reach of Underwood Creek, WI, 2018-2021 Temperature, soil property, and floodplain infiltration data from a restored reach of Underwood Creek, WI, 2018-2021
This release contains data collected to study surface-groundwater interactions during flood events in the floodplain of a restored reach of Underwood Creek in Wauwatosa, WI. Continuous floodplain sediment temperature data was collected at 6 sites from May 2018 to October 2021. Temperature data was used in conjunction with soil thermal property measurements and published groundwater...
