Data

In 2024, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BOT), carried out comprehensive hydrographic and water-quality surveys, and activity and disturbance assessments of 44 total water bodies encompassing lakes and rivers within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and on-site field

This data release is the update of the U.S. Geological Survey (USGS) - ScienceBase data release Bera (2023), with the processed data for the period October 1, 2021, through September 30, 2022. This data release (DR) describes the watershed data management (WDM) database WBDR22.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and disc

Geochemical data for aqueous, mine tailings, and sediment samples collected from the Big River and Meramec River drainage basins in southeastern Missouri are presented. The Big River drains historical lead, zinc, and barite mining districts, including the Old Lead Belt (OLB). Underground mining in the OLB resulted in large mine-waste chat piles and tailings impoundments that have released material

Topographic data were collected along six reaches (study reach 1, study reach 2, study reach 3, study reach 4, study reach 5, and study reach 6) along Caulks Creek in Wildwood, Missouri, on multiple dates, using terrestrial light detection and ranging (t-lidar), Global Navigation Satellite System (GNSS), and conventional surveying techniques (Rydlund and Densmore, 2012).These data are high-resolut

In 2023, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BoT), conducted comprehensive hydrographic and water quality surveys, along with activity and disturbance assessments of 58 total waterbodies encompassing lakes, rivers, and canals within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase data release by Bera (2023), with the processed data through September 30, 2023. Values for the variables and flags in the text files do not exactly match with the values in the ARGN22.wdm file during the period 01/01/1948 – 09/30/2022. ARGN22.wdm (Bera, 2023) is updated with the correct meteorological data and flag f

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

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

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

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,

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
