This data release provides phytoplankton and fish environmental DNA (eDNA) and cyanotoxin biosynthesis gene abundance data from an algal bloom at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. Algal bloom samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and...

This data release provides cyanobacteria identification and enumeration data at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected in 2022. Sixteen environmental samples and four quality assurance replicates were collected from two locations, one at the end of the dock and one at the shoreline, between September 21, 2022 and September 22, 2022.

A 2D HEC-RAS hydraulic model was developed to simulate flow velocities and shear stresses within a reach of the Kalamazoo River in southeastern Michigan from the Trowbridge Dam to the Allegan City Dam. The development of the 2D HEC-RAS model is described in the associated U.S. Geological Survey Scientific Investigations Report 2025-XXXX. This model archive contains all the files needed...

This data release provides phytoplankton environmental DNA data and cyanotoxin gene qPCR data from an algal bloom at Ash River Boat Docks on Kabetogama Lake, Voyageurs National Park, Minnesota, USA (USGS site ID 482603092511801) collected in 2021 and analyzed by the commercial laboratory Jonah Ventures. We sampled cyanobacteria over a 24-hour period at Ash River Boat Docks in Kabetogama...

This dataset details mercury (Hg) concentrations and carbon, nitrogen, and sulfur isotopes for Black and White tegus (Salvator merianae) collected in and around Everglades National Park between 2022 and 2024. Tegus (n = 115) were collected from 54 sites. Mercury in tegu muscle tissue ranged from 4.1 to 1200 ng g-1. Additional matrices such as livers and blood were measured on a subset of...

Burmese Pythons are an invasive reptilian species that has spread throughout southern Florida. Mercury (Hg) concentration in python tail muscles were examined across the Great Everglades region in two periods, 2001 - 2011 and 2014 - 2019. The python samples collected spanned a large range of habitats, including wetland, forested, and urban areas. In 2022 tissues from the offspring six...

This model application data release provides the data processing and model code used to generate predictions of daily stream water temperature across the contiguous United States from 1979-2021. We used a recurrent graph convolutional network (RGCN) algorithm to make daily stream temperature predictions. Stream water temperature observations, along with forcing data consisting of daily

This data release contains concentration and hazard score data for 16 contaminants of emerging concern (CECs) collected from surface waters throughout the Great Lakes basin. Concentration data were compiled from various online, published, or internal sources. Original data represent work conducted by federal, state, and local entities over a span of 30 years (1991 - 2021). Hazard scores...

This dataset contains a list of words that occurred at least 100 times from a news media search in LexisNexis, a large news archive database, about water bottling facilities in the U.S. from 1990 to 2024. Each word listed was classified as typically discussed in the context of the environment, the economy, both or neither. The data was used to conduct natural language processing lexicon...

USGS scientists enumerated bacteria, including bacterial pathogens, from surface water and sand/sediment collected at an intertidal site (mudflat) near the outfall the Palo Alto Regional Water Quality Control Plant (RWQCP). This site has been monitored for metal concentrations and benthic invertebrate community for the last 30 years. Continued efforts to document changes in pollutant

In support of the U.S. Geological Survey (USGS)-Next Generation Water Observing System (NGWOS) program, water quality data were collected in 2022-2023 in the Illinois River Basin—the third USGS Integrated Water Science (IWS) basin. These data were collected to document spatial heterogeneity in water quality across seasons and hydrologic conditions and to improve predictions of carbon and...

Geomorphic assessment and sediment data were collected in 2017 for an integrated sediment fingerprinting and stream corridor-based sediment budget study of Plum Creek, a tributary to the Lower Fox River and Green Bay, Wisconsin. Data were collected for 30 stream reaches and include quantitative and qualitative measurements of channel geometry, bank and gully erosion, soft bed sediment...
