A fully calibrated and validated SWAT model was used to provide watershed simulation results including irrigation water availability, crop evapotranspiration, outflow, and other components of the water budget such as groundwater recharge under different climate conditions (Dry (access1_0 rcp85) and Wet (fio_esm rcp45); Samimi et al., 2022), and selected environmental water allocation scenarios. The results are presented in the annual time interface for each Hydrologic Response Unit (HRU) in the watershed. We later aggregated these data to determine the values of each related component across the watershed. The data are available as open source to the public.
This folder contains summaries of droughts based on percentiles estimates of groundwater levels from NWIS and NGWMN for various time periods. It also contains various associated files that were used in assembling and producing this dataset. Additional information regarding NWIS groundwater data can be found here: USGS Groundwater Data for the Nation. More information regarding the NGWMN can be found here: National Ground-Water Monitoring Network (usgs.gov) -------------------------------------- Explanation of file names: The first several pieces are the type of data use to create the file "groundwater_percentiles" After this is the time period of analysis, e.g. "1970-2020" Next is the percentile calculation method,...

This folder contains percentiles from the levels record for monthly data from groundwater wells stored in NWIS and NGWMN. -------------------------------------------- Each of these zip folders contains percentiles calculated on these monthly groundwater levels for the period specified in the title. Both continuous monitoring sites and tape downs were condensed to monthly values by taking the first level measurement that occurred within the month. Sites with more than 33% of month values missing from any decade in the period were excluded. Each daily flow was grouped 2 different ways with flows in the month, and all site values. For each group the percentile/fraction of level ranking was computed for each given flow...

Data consist of census counts of Pliocene-Pleistocene benthic and planktic foraminifera from sites U1523, U1522, and U1521 collected from the Ross Sea on IODP expedition 374. In total, counts of individuals from 205 samples are included.

Clean water is important for a variety of uses, including drinking, recreation, and as habitat for aquatic species. Nonpoint-source pollution, such as nutrients, sediment, and pesticides from agricultural runoff, is a major cause of impaired water quality in the United States . Vegetation and soil in natural land cover help to remove pollutants from runoff water before it reaches streams and other waterways by slowing water flow and physically trapping sediment. To assess the spatial distribution of water purification potential in the southeastern United States, we mapped the demand for purification as the total area of agricultural land and the supply of natural land cover in the flowpath over which water moves...
Habitat condition, both acres flooded and timing of inundation, were determined using remote sensing images from Landsat 5 and 8 for the Lower Klamath Basin, the representative basin for the southern Oregon and northeast California (SONEC) region. The dataset includes proportional water coverage (acres) for 8,825 distinct patches in Lower Klamath over 6 different time periods (1984-89; 1990-94; 1995-99; 2000-04; 2005-09; 2010-16), with a total of 368,301 acres of possibly foreageable land.

The U.S. Geological Survey in cooperation with the Arkansas Natural Resources Commission, the Arkansas Geological Commission, and the Louisiana Department of Transportation and Development has monitored water levels in the Sparta Sand of Claiborne Group and Memphis Sand of Claiborne Group since the 1920's. Ground-water withdrawals have increased while water levels have declined since monitoring was initiated. This report has been produced to describe ground-water levels in the aquifers in the Sparta Sand and Memphis Sand and provide information for the management of this valuable resource. The 2005 potentiometric-surface map of the aquifers in the Sparta Sand and Memphis Sand was constructed using water-level data...

Simulated daily averaged surface water permit requested diversions and diversions modeled in the spatially refined model region within the Canadian River Basin RiverWare model. Values reported are for forty-six (46) scenarios implementing combinations of 1) three various climate model outputs for three various representative concentration pathways, 2) three various reservoir water right policy assumptions, and 3) three various projected future demands from 1983 through 2099. The RiverWare model was used to determine the impacts on regulated flows, reservoir levels, and water permit diversions. RiverWare software was used for this project because of its ability to simulate water use, reservoir operations, water right...

The data set contains temporal chloride concentrations (mg/L) and specific conductance (uS/cm) values for 32 wetlands and groundwater monitoring wells as well as the date(s) sampled and the laboratory where the water quality analyses were conducted. The ratio of chloride concentration to specific conductance is referred to as the Contamination Index. In this region, values greater than 0.035 are used to identify water quality samples that are contaminated with co-produced water from energy development.

Water temperature were recorded for six groundwater springs or seeps within the Neversink Reservoir Watershed, NY at hourly logging intervals between May - October 2022 using a water temperature data logger (HOBO TidbiT v2). Data are reported in degrees celsius. Data loggers were either placed within a pool of water (bedrock springs) or driven into the shallow subsurface (non-bedrock springs) at approximately 0.5 meter depth at seep location.

As part of a large-scale study of nitrate contamination on Kirtland Air Force Base in central New Mexico, the USGS collected groundwater and surface water samples for artificial sweetener analyses. Samples were collected following standard USGS procedures (U.S. Geological Survey, variously dated), filtered to 0.45 microns, and frozen until analysis. Artificial sweeteners analyzed include neotame, acesulfame-K, aspartame, saccharin, and sucralose. Of the 49 sites sampled, 17 sites had measurable detections of artificial sweeteners. Neotame was the most commonly detected sweetener (n=12) followed by saccharin (n=5), acesulfame-K (n=2), aspartame (n=1), and sucralose (n=0). Concentrations ranged from 0.0003–0.011 μg/L...

The impacts of climate change on cold water species will likely manifest in populations at the trailing edge of their distribution. Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis, RGCT) occupy arid southwestern U.S.A. streams at the southern-most edge of all cutthroat trout distributions; thus making RGCT particularly vulnerable to the anticipated warming and drying in this region. However, RGCT may possess a portfolio of life-history traits that aide in their persistence, attributes commonly observed in trailing edge populations. We used otolith and multistate capture-mark-recapture data collected along a temperature and stream drying gradient to determine how these environmental constraints influence...

Water-level measurements of wells were taken in the Upper Floridan aquifer between the dates of May 2 and June 23, 2010. A GIS shapefile of these water-level measurements was constructed and released as part of a prior USGS publication (Kinnaman and Dixon, 2011). This ArcGIS layer was updated in August 2014 to include salinity-based density corrections to water levels in those areas of south Florida where water in the subject aquifer is not fresh. The density corrections to water levels result in the portrayal of the “equivalent freshwater head” values in brackish and saline areas of the Upper Floridan aquifer where water quality data were available.
