Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and elevations of observed water surface and recovered high-water marks are being provided at select locations because of the high water observed during bathymetric data collection after a spring flood in 2022.

Replicate water-quality samples are collected and prepared in the field and analyzed in the laboratory in identical ways so that they are considered to be the same in composition and analysis (Mueller and others, 2015). This data set includes one table of duplicate National Water-Quality Assessment Project (NAWQA) surface water and groundwater samples collected between October 1, 2012 and September 30, 2015 and analyzed by the USGS National Water Quality Laboratory (NWQL) using direct aqueous-injection liquid chromatography-tandem mass spectrometry (Schedule 2437; Sandstrom and others, 2015) for the determination of 225 pesticides at 288 sites. Mueller, D.K., Schertz, T.L., Martin, J.D., and Sandstrom, M.W., 2015,...
This U.S. Geological Survey Data Release contains the associated data described in the Scientific Investigations Report, "Trends in water quality of selected streams and reservoirs used for water supply in the Triangle area of North Carolina, 1989-2013". Since 1989, the U.S. Geological Survey and a consortium of local governments have tracked water-quality conditions and trends in the water-supply reservoirs and streams in the Triangle area of North Carolina located within the upper Cape Fear and Neuse River Basins. Temporal trends in water-quality were analyzed for thirteen stream and eight reservoir sites. Seventeen water-quality parameters and constituents were examined at these sites.
The U.S. Geological Survey (USGS) National Water Quality Program (NWQP) provides an understanding of water-quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions. The Surface Water Trends (SWT) project of NWQP evaluates the directions, periods, and statistical significance of trends in water quality in streams and rivers. This data release was generated for SWT and provides annual agricultural pesticide use (1992-2014) for selected watersheds where long-term water quality is measured and where subsequent trend analysis will be conducted. County-level pesticide use estimates for 33 compounds were allocated to agricultural...
The U.S. Geological Survey (USGS) National Water Quality Network - Rivers and Streams (NWQN) is comprised of 110 surface-water monitoring sites designed to track ambient water-quality conditions across the nation. Although numerous constituents, including pesticides, have been collected at many of these sites since 1991, glyphosate and its metabolite aminomethylphosphonic acid (AMPA) were not routinely measured in NWQN water samples prior to 2014. Because of the widespread use of glyphosate for agricultural and nonagricultural applications, in 2014, these two compounds were added to the NWQN. This dataset includes concentrations of glyphosate and AMPA from water samples collected from 2015 through 2017 at 70 NWQN...
Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below the sediment-water interface (lakebed). Stilling wells were screened open to the lake. Continuous water-level data were collected at nine locations using submerged pressure transducers. One barometric pressure transducer was deployed so that continuous water-level data could be barometrically compensated. Discrete depth-to-water check...
In 2015, the total amount of water withdrawn in Florida was estimated at 15,319 million gallons per day (Mgal/d). This includes 9,598 Mgal/d of saline water and 5,721 Mgal/d of fresh water. Groundwater accounted for 3,604 Mgal/d and surface water accounted for 2,117 Mgal/d of the fresh water withdrawals. Surface water accounted for 9,400 Mgal/d and groundwater 198 Mgal/d of the saline water withdrawals. Water withdrawals are also tabulated by category (public supply, domestic self-supplied, commercial-industrial-mining self-supplied, agricultural irrigation, recreational-landscape irrigation, and power generation) and water management district (Northwest Florida, St Johns River, South Florida, Southwest Florida,...

This dataset consists of a national 30-meter raster which classifies pixels representing water from the National Land Cover Database 2016 (NLCD 2016) according to their estimated velocity regime. At the broadest classification, the data are mapped into two groups: “Lentic”, representing water bodies such as lakes, ponds, oceans, and bays, and “Lotic”, representing flowing water, such as streams, rivers, and canals. These are further broken into 12 subordinate classes ordered according to velocity. These include categories of retention time for water in lakes/ponds and flow velocity for streams/rivers. The classes are derived based on information from the NHD High- and Medium-Resolution databases. Of the 470.7 million...
This product is a series of six national 1-kilometer (km) raster datasets, for five year intervals between 1985 and 2010, representing USGS Water Use "Total Fresh Water Withdrawals", allocated to areas of land use representing anthropogenic use. Pixels representing anthropogenic uses (urban, agriculture, and mining land uses) are derived from the NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product (Falcone, 2015), a series of decadal national raster datasets for the period 1974-2012. The raster datasets created here are intended as a source of information for estimating water use for watersheds, at the scale of HUC12 watersheds and coarser. Units are millions of gallons per day (mgd) per square km.

In 2016, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 551 million gallons per day (Mgal/d) from fresh water sources. Surface water accounted for 492 Mgal/d (89 percent) and groundwater accounted for 59 Mgal/d (11 percent). Population served by public-supply water systems accounted for 3.4 million people, almost 100 percent of the total population. Total domestic water use was estimated at 396 Mgal/d and it is represented as the summation of deliveries from public-supply water systems to domestic users and self-supplied domestic withdrawals. The average per capita domestic water use, which represents the daily water use for the population that is supplied by public-supply water...
This model archive documents the Soil-Water-Balance (SWB) model used to simulate potential recharge for portions of Pennsylvania and Maryland from 2000 to 2021. The Pennsylvania and Maryland SWB model was used to create output at a 250 meter grid scale.
