High concentrations of uranium were detected in samples from wells used for domestic drinking water supplies in the San Joaquin Valley. Of 163 domestic wells sampled by the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) and the National Water Quality Program (NWQP) in 2008-2015, 26 percent had uranium concentrations greater than the U.S. Environmental Protection Agency maximum contaminant level (EPA MCL) of 30 µg/L, with 13 percent of the wells having uranium concentration between 100 µg/L and 450 µg/L. To evaluate the potential anthropogenic and geologic causes of these anomalously high uranium concentrations, Rosen and others (2019) compiled water quality and...

Beaches and water recreation are important to the South Padre Island, Texas area and across the United States. The movement of sediment in channels along beaches and the nearshore environment is important for coastal stakeholders and resource managers. Sediment removed by maintenance dredging is often placed back into the littoral system for potential beach replenishment. The movement of sediment from offshore berms to onshore beaches is not well known. Sediment transport is highly dependent on local current conditions and seasonal conditions. The U.S. Geological Survey, in cooperation with the City of South Padre Island, completed an oceanographic field study from August 2018 to February 2019 to investigate the...

Locations of focused (or ‘preferential’) groundwater discharge to surface water are often hydrologically and ecologically important, yet our ability to predict the spatial distribution and water quality of preferential riverbank discharges is limited at the scale of river networks. To advance the understanding of the physical controls on riverbank groundwater discharge processes, discharge zones can be mapped efficiently using handheld and drone-based thermal infrared cameras. Groundwater discharge locations can be identified based on ‘anomalous’ thermal signatures, such as relatively cold riverbank zones in summer and warm riverbank zones in winter. Thermal infrared imaging can be combined with concurrent direct...

This dataset supercedes an earlier data release and includes all previous data in addition to data from 2019. These data represent the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Micro-g LaCoste D-series relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical gradients between the different measuring heights of the absolute- and relative-gravity meters were measured using...

Streamflow data and statistics are vitally important for proper protection and management of both the water quality and water quantity of Alabama streams. Such data and statistics are available at U.S. Geological Survey streamflow-gaging stations, also referred to as streamgages or stations, but are often needed at ungaged stream locations. To address this need, the U.S. Geological Survey, in cooperation with numerous Alabama State agencies and organizations, developed regional regression equations for estimating selected low-flow frequency statistics and mean annual flow for ungaged locations in Alabama that are not substantially affected by tides, regulation, diversions, or other anthropogenic influences. This...

This data release provides estimates of annual agricultural use of pesticide compounds in counties of the conterminous United States, for years 2013-17, compiled by means of methods described in Thelin and Stone (2013) and Baker and Stone (2015). For all States except California, U.S. Department of Agriculture county-level data for harvested-crop acreage were used in conjunction with proprietary Crop Reporting District-level pesticide-use data to estimate county-level pesticide use. Where Crop Reporting District data were not available or were incomplete, estimated pesticide-use values were calculated with two different methods, resulting in a low and a high estimate based on different assumptions about missing...
The U.S. Geological Survey (USGS), in cooperation with the Kootenai Tribe of Idaho, used streamflow measurements at 14 partial-record sites and related them to nearby USGS real-time streamgages (index sites) to provide daily mean streamflow values at ungaged (partial-record) sites. Daily mean streamflow was estimated by developing a regression relationship between streamflow at each partial-record site and the index site for the period of record of the index site. The daily mean streamflow at partial-record sites will support the Kootenai Tribe of Idaho effort to understand fish and wildlife habitat in the watershed and provide streamflow estimates for Kootenai River tributaries for use in hydraulic modeling that...

Near-field remote sensing methods were used to collect Doppler velocity and pulsed stage radar data at 10 conventional U.S. Geological Survey streamgages in river reaches with varying hydrologic and hydraulic characteristics. Basin sizes ranged from 381 to 66,200 square kilometers and included agricultural, desert, forest, mixed, and high-gradient mountain environments. During the siting and operational phases, radar-derived mean-channel (mean) velocity and discharge were computed using the Probability Concept (PC) and were compared against conventional instantaneous measurements and stage-discharge time series. During siting phase, radars were located, installed, and PC parameters computed. To test the efficacy...

The U.S. Geological Survey (USGS) Oklahoma-Texas Water Science Center, in cooperation with the Oklahoma Department of Transportation, updated basin-characteristic data for Oklahoma streams with drainage areas of less than 2,510 square miles. Basin characteristics were updated or created for 248 streamgages. The previously published Oklahoma generalized skew map, a necessary element in the development of the peak-streamflow frequencies was updated. Compared to a previous dataset described in (Lewis, 2010), this dataset incorporates an additional 9 years of annual peak-streamflow data, including 2 years when major peak-streamflows were recorded (2015 and 2017). The additional years of data collection since the publication...
