The data release consists of two companion air and water temperature datasets collected as part of the U.S. Geological Survey (USGS) Next Generation Water Observing System (NGWOS) program with data from both the Little Lehigh and White Clay Creek Watersheds in the Delaware River Basin. Data consists of 15-minute temperature data during the 7/2021 – 12/2022 study period for 21 air and 49 water locations (which include 6 continuous monitoring USGS streamgages) in the Little Lehigh Creek watershed and 8/2021 – 1/2023 for 28 air and 36 surface water locations (including 6 continuous monitoring USGS streamgages) in the White Clay Creek watershed. Datalogger installation locations for surface water locations were targeted...

This data release provides model inputs and outputs for a model that predicts redox conditions in groundwater in the contiguous United States. Input variables describe the hydrology, soils, geology, and hydrologic position of groundwater sample locations. The data release accompanies a journal article that describes model development and applications (Tesoriero_and_others_2023).

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 annual peak flows is stationary. Better understanding of long-term climatic persistence and further consideration of potential climate and land-use changes have caused the assumption of stationarity to be reexamined. This data release contains input data and results of a study investigating hydroclimatic trends in peak streamflow...
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. Discrete velocity, cross-section area, and temperature profiles at several locations within the study reach provided model calibration data. The model was calibrated to 2021 and 2022 observed data and validated with 2020 data. Model output consisted of 2-dimensional, laterally averaged hydrodynamic and water-temperature...

The USGS, in cooperation with the U.S. Bureau of Land Management (BLM), created a series of geospatial mapping products of the Scotts Creek Watershed in Lake County, California, using National Agriculture Imagery Program (NAIP) imagery from 2018, 2020 and 2022 and Open Street Map (OSM) from 2019. The imagery was downloaded from United States Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) Geospatial Data Gateway (https://datagateway.nrcs.usda.gov/) and Geofabrik GmbH - Open Street Map (https://www.geofabrik.de/geofabrik/openstreetmap.html), respectively. The imagery was classified using Random Forest (RF) Modeling to produce land cover maps with three main classifications - bare,...
This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

This dataset includes pipe-flow monitoring data in sewers used to analyze the water budget at RecoveryPark in Detroit, Michigan. These are provided as 3 text comma separated format files at sewer locations that drain the study area. In addition, there are 6 text comma separated format files containing the Rhodamine dye tracer concentrations collected in the combined sewer locations for this study. The Dye tracer files constitute two separate dye tracer tests in different parts of the sewer system done in the same day.

This data release consists of a Microsoft® Access database that contains groundwater withdrawal estimates from known and approximate well locations (withdrawal points) in the Death Valley regional groundwater flow system (DVRFS) to support a regional, three-dimensional, transient groundwater flow model (Belcher and others, 2017; Halford and Jackson, 2020). The database provides information for each withdrawal point including estimated location and completion interval (Moreo and others, 2003). Groundwater withdrawal estimates for each withdrawal point have been compiled by water use and year. Uncertainty was assigned to the annual withdrawal values based on the use and method of estimation (Moreo and others, 2003)....
This dataset describes field-measured qualitative stream channel characteristics indicative of incision and remotely-measured predictions of channel incision from lidar in three headwater streams in the Piedmont physiographic region of Maryland. The files within the field-measured channel incision folder include 1) a point file of original survey locations with a description of channel characteristics and 2) a stream network file with the field-surveyed degree of channel incision classified by stream reach. The file within the model-predicted channel incision folder includes stream networks for each watershed, and the incision prediction from lidar for the years 2002, 2008, 2013, and 2018.
Optical sensors measuring fluorescence of dissolved organic matter (fDOM) are increasingly used in water quality studies because they provide proxy measurements for a variety of contaminants and constituents of concern including metals and wastewater effluent. Similarly, sensors measuring fluorescence of chlorophyll (fChl) and phycocyanin (fPC) have gained popularity to measure phytoplankton concentration, biomass, and even primary productivity. Optical sensors require calibration using a calibration standard solution which is diluted from a working stock solution. However, preparation of stock solutions is challenging because they are difficult to prepare accurately, need to be prepared in a laboratory setting,...

This data release documents time-series analyses of aqueous-chemistry data from public-supply wells (PSWs) and associated potential explanatory factors to characterize responses of groundwater quality to drought and recovery periods in California’s San Joaquin Valley (SJV) during 2000-2022. Annual median nitrate values were computed for PSWs throughout the SJV during the period of study. Median annual nitrate values were calculated at all PSWs with available data in the SJV, resulting in a total of 698 PSWs with complete annual records after single-year linear gap imputation. A total of 237 of these records were classified as “low variance” because they contained proportions of identical values exceeding 80 percent...
Harmful algal blooms (HABs) have recently been observed in rivers, including the Illinois River in the Midwest United States. The Illinois River Basin has a history of eutrophication issues, primarily caused by the excessive loading of nitrogen and phosphorus from urban and agricultural sources. Recent events have seen the emergence of cyanobacterial harmful algal blooms in the area. This data release provides early warning indicator (EWI) metrics derived from a continuous chlorophyll concentration dataset obtained from seven water quality monitoring sites along the Illinois River. These metrics include the first-order autoregressive process (Ar1) and the standard deviation (SD) of chlorophyll, which serve as leading...
