Data

Important hydrological and geotechnical information from U.S. Geological Survey (USGS) reports detailing selected paleotectonic geologic periods, including the Jurassic (McKee and others, 1956), Triassic (McKee and others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979), were digitized from scanned plates...

This data release contains discrete chlorophyll data, specifically corrected chlorophyll a, uncorrected chlorophyll a, and pheophytin pigments, from inland waters in the Illinois River Basin for 1981–2023. These data are discrete samples (collected in the field and analyzed in the laboratory) of plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, canals...

This data release contains results of a study investigating changes in streamflow seasonality associated with hydroclimatic variability in the north-central United States, including nine States (Illinois, Iowa, Michigan, Minnesota, Missouri, Montana, North Dakota, South Dakota, and Wisconsin). Peak-flow records from unregulated U.S. Geological Survey streamgages were used to evaluate...

This data release contains data in support of "The Joint Effect of Changes in Impervious Cover and Climate on Trends in Floods: A Comparison of Panel and Single-Station Quantile Regression Approaches" (Over and others, 2025). It contains input and output data used to analyze the effect of impervious cover and climate changes on trends in floods using three regression approaches. The...

The U.S. Geological Survey (USGS), in cooperation with the Fond du Lac Band of Lake Superior Chippewa (FDLB), Minnesota, analyzed the hydrologic and hydraulic conditions within the Stoney Brook watershed. The Stoney Brook watershed covers an area of 100.8 square miles in Carlton and St. Louis counties with most of the watershed within the Fond du Lac Reservation. Wild rice, which is...

Information of hydrogeologic and geologic importance from the book, "Lithofacies Maps: An Atlas of the United States and Southern Canada" (Sloss and others, 1960) detailing geologic periods, including the Cambrian, Ordovician, Silurian, and Devonian were digitized from scanned maps. Isopach contours were captured and, along with Geologic Map of North America (GMNA) information (Garrity...

The U.S. Geological Survey (USGS), in cooperation with Scott Air Force Base (SAFB), Illinois, assessed the effects of temporal land-use development in the Silver Creek Basin, the potential effects of projected changes in future precipitation, and the effects of added detention storage in selected tributaries near SAFB. A hydrologic model was used to simulate precipitation runoff and...

These data represent a Global Positioning System (GPS) survey generated September 18, 2024, using Trimble R10 2 Real-Time Kinematics (RTK) and Global Navigation Satellite Systems (GNSS). Survey extends along the Cedar River streambed in Cedar Falls, Iowa, where a wastewater treatment diffuser pipe is installed. Cross-sectional representations were produced to depict stream depth and...

Des Moines Water Works (DMWW) is a regional municipal water utility that supplies residential and commercial water resources to about 600,000 customers in Des Moines, Iowa, and surrounding municipalities in central Iowa. DMWW has identified a need for increased water supply and is exploring the potential for expanding groundwater production capabilities in the Des Moines River alluvial...

The Bank Stability and Toe Erosion Model (BSTEM) version 3.3.1 (Ursic and Langendoen, 2021) was used to predict bank retreat at five locations along Caulks Creek, Wildwood, Missouri, for a selection of design storm scenarios. BSTEM is a macro-enabled Excel spreadsheet (.xlsm file) that simulates the retreat of a bank profile due to a combination of fluvial and geotechnical processes...

Substantial incision and widening of Caulks Creek within the City of Wildwood, Missouri, in western St. Louis County, poses a threat to stormwater and transportation infrastructure along with effects to residential and recreational property. Hydrologic and hydraulic models were used to estimate probabilistic streamflows and characterize and assess spatial and temporal changes in erosion...

This data release contains the R source code, inputs, and selected outputs associated with the turbidity-based regression models used to estimate total phosphorus concentrations and loads for the Missouri River at St. Joseph and Hermann, Missouri, for water years 2008–22. Additionally, the R source code, inputs, and selected outputs for LOADEST models used to estimate daily total...
