Salinity is the sum of dissolved salts in water and can have major effects on surface-water quality in semi-arid regions such as southwestern Wyoming. High levels of salinity can make water unsuitable for wildlife or irrigation. A wide variety of processes influence the salinity of surface waters, including mobilization of salts or concentration of salts already in the water. Disturbance of soils that contain natural salts below the surface can lead to salt mobilization as the exposed salts come into increased contact with water from rain, snowmelt, or streamflow. Because soil disturbance is inevitable with energy development, increased stream salinity is a potential concern in developed watersheds. In 2005, energy...
Description of Work USGS scientists provide expertise, capacity and support for the implementation of Lakewide Management Plans (LaMPs) and the associated goals, objectives and targets for each of the Great Lakes, including Lake Superior. The LaMPs are critical binational groups that are important for promoting Great Lakes restoration. Specifically, LaMP efforts include compiling monitoring and research information into the Great Lakes web mapper (SiGL Mapper). The Mapper’s focus is on information that will result in recognition of areas where data are being collected, missing or sparse, and on areas where ecosystems are vulnerable.

U.S. Geological Survey, in cooperation with Miami-Dade County, performed a sequential, aquifer stress test from August 15 to October 12, 2011, on the Floridan aquifer system at the North District Wastewater Treatment Plant, in Miami-Dade County, Florida. Miami-Dade County stressed the Floridan aquifer system with four municipal injection wells at the North District Wastewater Treatment Plant. Injection wells IW–1, IW–3, and IW–4 stressed the aquifer system with injection of as much as 1.8 cubic meters of effluent per second. Injection well IW–2 stressed the aquifer system with pressure release from the injection zone, caused by reverse flow of as much as 0.04 cubic meters of formation fluid mixed with effluent...
The northern Gulf of Mexico coast spans two major climate gradients and represents an excellent natural laboratory for developing climate-influenced ecological models. In this project, we used these zones of remarkable transition to develop macroclimate-based models for quantifying the regional responses of coastal wetland ecosystems to climate variation. In addition to providing important fish and wildlife habitat and supporting coastal food webs, these coastal wetlands provide many ecosystem goods and services including clean water, stable coastlines, food, recreational opportunities, and stored carbon. Our objective was to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure...

Files contain hydrodynamic and sediment transport data for the location and deployment indicated. Time-series data of water depth, velocity, turbidity, and temperature were collected in San Pablo Bay and China Camp Marsh as part of the San Francisco Bay Marsh Sediment Experiments. Several instruments were deployed in tidal creek, marsh, mudflat, and Bay locations, gathering data on water depth, velocity, salinity/temperature, and turbidity. Deployment data are grouped by region (Bay channel (main Bay), Bay shallows, tidal creek, or marsh/mudflat/upper tidal creek). Users are advised to check metadata and instrument information carefully for applicable time periods of specific data, as individual instrument deployment...
Groundwater-quality data were collected from 559 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program from January through December 2014. The data were collected from four types of well networks: principal aquifer study networks, which assess the quality of groundwater used for public water supply; land-use study networks, which assess land-use effects on shallow groundwater quality; major aquifer study networks, which assess the quality of groundwater used for domestic supply; and enhanced trends networks, which evaluate the time scales during which groundwater quality changes. Groundwater samples were analyzed for a large number of water-quality...

Consistent with the National Park Service’s philosophy, Fossil Butte National Monument is managed to protect the Monument’s resources and provide opportunities for public enjoyment. Fossil Butte National Monument was created primarily to protect paleontological resources; however, the mandate of the agency’s enabling legislation “to conserve the scenery and the natural and historic objects and the wildlife therein…” also recognizes the importance of natural process, native wildlife species, and the habitats on which they depend. Sizeable herds of elk spend part of the fall and winter within the Monument’s boundaries and provide numerous viewing opportunities for visitors. Collaboration among the USGS, the National...
This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within local and network stream catchments as well as 90 m local and network buffer of stream reaches throughout the conterminous U.S. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. Variables summarized at the catchment scale include measures of anthropogenic...

Invasive annual grasses, such as cheatgrass (Bromus tectorum L.), have proliferated in dryland ecosystems of the western United States, promoting increased fire activity and reduced biodiversity that can be detrimental to socio-environmental systems. Monitoring exotic annual grass cover and dynamics over large areas requires the use of remote sensing that can support early detection and rapid response initiatives. Here, we integrated in situ observations, weekly composites of harmonized Landsat and Sentinel-2 (HLS) data, maps of biophysical variables (e.g. soils and topography) and machine learning techniques to develop fractional estimates of exotic annual grass cover at a 30-m spatial resolution from 2016 to 2018....
This geodatabase contains 90 meter buffers of streams within the National Hydrography Dataset Plus Version 1 (NHDPlusV1). These buffers were developed by converting NHDPlusV1 flowlines to a 30m grid, then running a euclidean allocation function in ArcPy to generate buffer zones. For flowlines representing artificial paths within NHD area river polygons, buffers extend from the outside edges ("banks") of the polygon outward. The source code for buffer development can be found at https://github.com/ArthurCooper/NFHP-Buffer-Code.

This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the glacial aquifer system east of the Rocky Mountains in the conterminous United States at a 1-kilometer (km) resolution for the period 1980-2011. The calibrated SWB model in this model archive and associated U.S. Geological Survey Scientific Investigations Report is referred to as the glacial SWB model. Potential groundwater recharge was determined on a daily basis as precipitation in excess of interception, runoff, evapotranspiration, and soil water storage capacity. Daily groundwater recharge amounts were aggregated to an annual basis for grids available in this model archive. Potential recharge...

The agro-hydrologic VegET (VegetationEvapotranspiration) model uses a water balance approach to simulate daily soil moisture (SM), actual evapotranspiration (ETa), and runoff (R). We enhanced the model to include snow accumulation and melt processes along with the separation of runoff into surface runoff and deep drainage and implemented the code using cloud technology. This publication is providing the supporting data for the updated methods and provides evaluation results for the United States and the Greater Horn of Africa.
