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.

Bioassay data for aircraft deicer and anti-icer formulations and surface water receiving runoff from Milwaukee Mitchell International Airport from 1996-2021 Bioassay data for aircraft deicer and anti-icer formulations and surface water receiving runoff from Milwaukee Mitchell International Airport from 1996-2021
This data release includes two datasets: The first dataset includes results of bioassay (acute and chronic toxicity) tests on five aircraft deicer and anti-icer products, which were tested for determination of the 15-min EC50 (Aliivibrio fischeri), the acute LC50 (Ceriodaphnia dubia and Pimephales promelas), and the chronic IC25 (C. dubia, P. promelas, and R. subcapitata) at the...
Stream Network Capacity to Support Beaver Dams, Tualatin River Basin, Northwest Oregon Stream Network Capacity to Support Beaver Dams, Tualatin River Basin, Northwest Oregon
Beaver dams can help streams connect to their floodplains. These floodplain connections can expand the range of available aquatic habitats and aid in the restoration of stream and floodplain processes. North American beavers (Castor canadensis) occupy a wide variety of aquatic habitats; however, their ability to build dams, the agent of stream and floodplain change, is constrained in...
Hydraulic models of two beaver affected reaches in the Tualatin Basin, Oregon Hydraulic models of two beaver affected reaches in the Tualatin Basin, Oregon
Beaver dams affect stream hydraulics by temporarily impounding water in stream channels. Beaver dams and their associated impoundments can potentially influence streamflow hydrographs and stream hydraulics in multiple ways including altering the magnitude and duration of high flows, temporary storage of storm water, and the range and spatial distribution of water depths and velocities in...
Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2024 Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2024
The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) analyzed per-and polyfluoroalkyl substances (PFAS) in groundwater samples collected from domestic and public drinking water supply wells in California. GAMA-PBP is a cooperative program between the U.S. Geological Survey and the California State Water Resources Control Board. This...
Data from 346 streamgages used in the development of regional regression equations for the estimation of magnitude and frequency of floods at ungaged locations in New Mexico Data from 346 streamgages used in the development of regional regression equations for the estimation of magnitude and frequency of floods at ungaged locations in New Mexico
The U.S. Geological Survey (USGS), in cooperation with the New Mexico Department of Transportation, estimated the magnitude and frequency of floods corresponding to the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs; otherwise known as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods, respectively) for 346 selected streamgages in New...
Phytoplankton identification and enumeration data during an algal bloom in Kabetogama Lake, northern Minnesota, 2023 Phytoplankton identification and enumeration data during an algal bloom in Kabetogama Lake, northern Minnesota, 2023
This data release provides phytoplankton identification and enumeration data during an algal bloom at Ash River boat docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and one on the adjacent shoreline. Two quality assurance...
