Archive of the Hydraulic Model used in the Two-Dimensional Simulation of the Chain of Lakes on the Fox River near McHenry, Illinois

Forecasts of flows entering and leaving the Chain of Lakes on the Fox River in northeastern Illinois are critical information to water-resource managers operating the Stratton Dam at McHenry, Illinois. These managers determine the optimal operation of the Stratton Dam at McHenry, Ill., to manage Chain of Lakes pool levels and to help mitigate flooding in the Chain of Lakes system. In 2020, the U.S

Modeled Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2022

During water years 2016–2022 (a water year begins on October 1 and ends on September 30), the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (Illinois EPA), operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from the State of Illinois to the Mississippi River. This data

Model Archive and Hydraulic and Fluvial Egg Drift Simulator (FluEgg) Results for Simulations of Grass Carp Eggs and Larval Drift in the Lower Sandusky River, Ohio

The U.S. Geological Survey simulated the drifts of grass carp eggs in the lower Sandusky River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) (Garcia and others, 2013; Zhu, 2019). The hydraulic inputs used in the FluEgg simulations were generated using a one-dimensional (1D) Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.3 model of the lower Sandusky River (HEC-RAS, 202

Bathymetric and Supporting Data for Selected Water Supply Lakes in Missouri, 2023

Water-supply lakes are the primary source of water for many communities throughout Missouri. Therefore, accurate and up-to-date estimates of lake capacity are important for managing and predicting adequate water-supply. Many of the water-supply lakes in Missouri were previously surveyed by the U.S. Geological Survey (USGS) in the early 2000s (Richards, 2013) and in 2013 (Huizinga, 2014); however,

Hydrodynamic and Water-Temperature Model of a 21-Mile Reach of the Upper Illinois River, Illinois, 2020 – 2022

A hydrodynamic and water-quality model (CE-QUAL-W2) was developed of a 21-mile reach of the upper Illinois River including a 3-mile reach of a major tributary, the Fox River.  The CE-QUAL-W2 model is 2-dimensional in the vertical and longitudinal directions and averaged over the lateral direction.  Continuous water quality and streamgage data provided time-series data for model boundary conditions

Aquaculture and irrigation water-use model (AIWUM) version 1.1 estimates and related datasets for the Mississippi Alluvial Plain

This data release contains monthly and annual water-use estimates from the aquaculture and irrigation water-use model (AIWUM) version 1.1 for the Mississippi Alluvial Plain, April 1999 to October 2019. Aquaculture and irrigation estimates contained in this data release are representative of groundwater withdrawal for six different categories: aquaculture, cotton, corn, rice, soybeans, and all othe

Bathymetry of Bubbly Creek and Chicago Sanitary and Ship Canal Sidings in Cook County, Illinois, July 2023

These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–19, 2023, hydrographic survey of Bubbly Creek and various sidings, harbors, and turning basins on the Chicago Sanitary and Ship Canal (CS&SC) in Cook County, Illinois. The survey includes all Bubbly Creek from the confluence with the CS&SC in the north to the Racine Avenue Pu

North Branch Chicago River and North Shore Channel Bathymetry in Cook County, Illinois, July 2023

These data are high-resolution bathymetry (riverbed elevation) in compressed LAS (*.laz) format, generated from the July 17–18, 2023, hydrographic survey of the North Branch Chicago River and North Shore Channel in Cook County, Illinois. The survey extends from near the North Avenue Turning Basin and Goose Island in the south, upstream to the Metropolitan Water Reclamation District (MWRD) Wilmette

Seepage Meter Data Collected at Crystal Lake, City of Crystal Lake, Illinois, 2020

Seepage meters measurements were collected at three locations along the northern shoreline and at three locations along the southern shoreline of Crystal Lake, located in the City of Crystal Lake, Illinois on October 28-30, 2020, and November 4-5, 2020. Seepage measurements directly measure the flux for the area captured by the seepage meter. A positive (gaining) flux is assumed when the volume in

Peak Streamflow Data, Climate Data, and Results from Investigating Hydroclimatic Trends and Climate Change Effects on Peak Streamflow in the Central United States, 1921–2020

Peak-flow frequency analysis is crucial in various water-resources management applications, including floodplain management and critical structure design. Federal guidelines for peak-flow frequency analyses, provided in Bulletin 17C, assume that the statistical properties of the hydrologic processes driving variability in peak flows do not change over time and so the frequency distribution of annu

Monitoring Data to Support the Operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018

The U.S. Geological Survey monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System, EDBS, on the Chicago Sanitary and Ship Canal, Chicago, Illinois. This data release is the 2018 water year summary of the EDBS monitoring data. Water surface flow reversals at the EDBS are monitor

Reconnaissance of Per- and Polyfluoroalkyl Substances (PFAS) in Selected Groundwater and Surface Water Sites in McHenry County, Illinois, 2020

Data were collected at 19 groundwater monitoring wells and 3 surface water locations across McHenry County, Illinois, in 2020 by staff from the U.S. Geological Survey (USGS) Central Midwest Water Science Center. Quality control samples (2 blanks and 1 replicate) were also collected to assess data reliability and precision. Samples were submitted to the USGS National Water Quality Laboratory in Den
