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).

This data release contains site information and potential explanatory factor data for 1,899 groundwater sites. These sites were used to assess groundwater quality in aquifers used for domestic and public drinking water supply in the southeastern San Joaquin Valley. The southeastern San Joaquin Valley (SESJV) study unit consists of five study areas whose boundaries are defined by the eponymous California Department of Water Resources groundwater subbasins of the San Joaquin Valley groundwater basin: Madera-Chowchilla, Kings, Kaweah, Tule, and Tulare Lake. The sites consist of 198 wells representing the domestic-supply aquifer and 1,701 wells representing the public-supply aquifer. The domestic-supply aquifer wells...
This USGS Data Release represents water and sediment quality data collected in the Grand Canyon region of northern Arizona. This dataset comprises water quality results from spring and stream sites in Grand Canyon that were sampled through a cooperative effort by U.S. National Park Service (NPS) personnel during 2016 and 2017. NPS personnel collected water samples from spring and stream sites in Grand Canyon. Water samples were filtered using a syringe and 0.45 µm filter and preserved with nitric acid. Filtered and preserved samples were analyzed by the USGS Geology, Geophysics, and Geochemistry Science Center Laboratory for a suite of elements using inductively coupled plasma - mass spectrometry (ICP-MS) methods...

This dataset comprises water quality results from monitoring sites on major tributaries of the Colorado River in the Grand Canyon region beginning in 2015. These tributary sites include Little Colorado River above the mouth near Desert View, Arizona (USGS site ID 09402300); Kanab Creek above the mouth near Supai, Arizona (USGS site ID 09403850); Havasu Creek above the mouth near Supai, Arizona (USGS site ID 09404115); House Rock Wash below Emmett Wash in Rider Canyon, Arizona (USGS site ID 363851111482000); and Paria River at Lees Ferry, Arizona (USGS site ID 09382000). Monitoring of the Little Colorado River, Kanab Creek, and Havasu Creek sites began in 2015, with other sites added later.

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 dataset is a collection of hyperspectral imagery profiles of algae, many associated with Harmful Algae Blooms (HABs). Data were collected using a microscope-based hyperspectral imaging system with the cooperation of the National Institute of Standards and Technology. Samples were collected from U.S. Geological Survey (USGS) water quality sampling efforts, to include water quality parameters and algal biomass. Data are shown in basic hyperspectral imagery form, normalized to 1.

This dataset comprises sediment chemistry results from monitoring sites on the Colorado River and major tributaries of the Colorado River in the Grand Canyon region beginning in 2016. Main-stem Colorado River sites include Colorado River near Grand Canyon (USGS site ID 09402500) and Colorado River above Diamond Creek (USGS site ID 09404200). The tributary sites include Little Colorado River above the mouth near Desert View, Arizona (USGS site ID 09402300); Kanab Creek above the mouth near Supai, Arizona (USGS site ID 09403850); Havasu Creek above the mouth near Supai, Arizona (USGS site ID 09404115); House Rock Wash below Emmett Wash in Rider Canyon, Arizona (USGS site ID 363851111482000); and Paria River at Lees...
This USGS Data Release represents time series water quality data collected at select spring sites in the Grand Canyon region of northern Arizona. This dataset comprises time series water quality results from select spring sites in the Grand Canyon region that were sampled using a MiniSipper auto sampler. These spring sites include Salt Spring (USGS Site ID: 360439112094101) and Willow 1 Spring (Site ID: 363357112440801). The MiniSipper auto sampler collects up to 250 five-mL, 0.45 um filtered and acidified water samples. Samples are stored in a 500' teflon tubing sample coil and adjacent water samples are separated by air bubbles (Chapin and Todd, 2012). Water samples are analyzed for a suite of elements using...

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...
