Data

This data release contains waterborne gradient self-potential (SP), surface-water temperature, surface-water conductivity and specific conductance, and surface-water nitrate concentration data measured continuously in the upper part of the Delaware River along approximately 123 kilometers (km) between Hancock and Port Jervis, New York. All of the data were measured from a kayak between...

This data release contains waterborne gradient self-potential (SP), surface-water temperature, and surface-water conductivity data measured continuously along approximately 72 kilometers (km) of the Rio Grande over the Mesilla part of the Hueco-Mesilla Bolson aquifer. The geophysical measurements were made from a kayak between June 26, 2020 and July 2, 2020 during peak releases of...

For more than 100 years, the Permian Basin has been an important source of oil and gas produced from conventional reservoirs; directional drilling combined with hydraulic fracturing has greatly increased production in the past 10 years to the extent that the Permian Basin is becoming one of the world's largest continuous oil and gas (COG) producing fields. These recent techniques extract...

This Data Release contains various types of hydrologic and geologic data from the Upper Rio Grande Focus Area Study from 1921-2017, including groundwater-level measurement data compiled and synthesized from various sources, water-level altitude and water-level change maps developed from the water-level measurement data every 5 years from 1980-2015, and the horizontal extent of 13...

A three-dimensional, finite-difference MODFLOW 2005 groundwater model using the Newton formulation solver (MODFLOW-NWT) was created for the Cimarron River alluvial aquifer in Payne County, north-central Oklahoma to assess the effects of current groundwater withdrawal rates with respect to current and future groundwater availability and on base flow in the Cimarron River. To better...

The U.S. Geological Survey (USGS) in cooperation with the Harris?Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District produced this dataset of groundwater?level altitudes and groundwater?level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston?Galveston region, Texas. This dataset...

This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston?Galveston region, Texas for 2020. The U.S. Geological Survey prepared this dataset in cooperation with the Harris?Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board, produced this data release that includes vector and raster geographic information systems layers used in the analysis and publication of a mean annual runoff and annual runoff variability map for 1940-2007 for Oklahoma. The data release covers all 69 8-digit hydrologic units with at least 1 square...

Arundo donax (Arundo Cane) is an invasive perennial reed that can grow more than 30 feet tall and has become established in riparian zones along rivers throughout the southwestern United States. It grows in thick stands, readily displaces native riparian habitat, and provides no habitat or food for native species in the ecosystems it disrupts (McWilliams, 2004). The Texas State Soil and...

The U.S. Geological Survey (USGS) undertook a 5-year study beginning in 2016 to assess groundwater availability for the aquifers proximal to the Gulf of Mexico from the Texas-Mexico border to the western part of the panhandle of Florida; these aquifers are collectively referred to as the coastal lowlands aquifer system. This study is one of several regional groundwater availability...

This data release contains compiled historical groundwater-withdrawal data for the Coastal Lowlands Aquifer System in Texas, Louisiana, Mississippi, Alabama, and Florida from 1925 to 2018. Most groundwater-withdrawals were distributed to groundwater wells and separated into water-use categories of industrial, production wells, power generation, mining, domestic, irrigation, livestock or...
