History matching of large hydrologic models is challenging due to data sparsity and non-unique process combinations (and associated parameters) that can produce similar model predictions. We developed an ensemble-based history matching and uncertainty quantification approach using an iterative ensemble smoother (iES) method for three cutouts of the National Hydrologic Model (NHM) and...

This data release contains relative abundance data of the Clostridium botulinum neurotoxin type E gene (bontE) in sediment cores collected from three nearshore depositional basins near Sleeping Bear Dunes National Lakeshore (SLBE), Lake Michigan, in September 2010. Sediment cores were collected using a box corer and maximum collection depth ranged from 23 to 42 centimeters. Each sediment...

This is an archive of model code used in statistical analysis of the influence of conservation implementation on water quality during surface runoff events at edge-of-field monitoring sites located in the Laurentian Great Lakes Basin, using data collected from 2012 to 2021. The workflow includes two types of analysis: 1) analysis of covariance (ANCOVA) for paired sites and 2) generalized...

A stormwater pond in Cherokee Park, Madison, Wisconsin was monitored to determine if changes to street cleaning operations in the contributing drainage area would influence pollution reduction efficiency. Event-based water samples were collected from the ponds inlets and outlet from September 2020 through October 2024 and analyzed for nitrogen, phosphorus, sediment and chloride...

This data release provides phytoplankton identification and enumeration data from an algal bloom at Lost Bay on Kabetogama Lake (USGS site ID 482747092503001) collected on September 20, 2022. These data were collected using a systematic grid design, 3 rows by 4 columns grid cells, where each grid cell contained a single sample location. A near-shore sample location, just outside the...

The U.S. Geological Survey (USGS) has regularly collected fish community data from wadable streams in the Milwaukee, Wisconsin area, beginning with the first recorded sample in 1993 and continuing through 2024. These data were collected via electrofishing and seining (in accordance with standard USGS protocols), with the intent of monitoring fish communities and water quality in the area...

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...

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...
