Water-level altitudes 2014 and water-level changes in the Chicot, Evangeline, and Jasper aquifers and compaction 1973-2013 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
Most of the land-surface subsidence in the Houston-Galveston region, Texas, has occurred as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot and Evangeline aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained...

Concentrations, loads, and yields of total phosphorus, total nitrogen, and suspended sediment and bacteria concentrations in the Wister Lake Basin, Oklahoma and Arkansas, 2011-13
The Poteau Valley Improvement Authority uses Wister Lake in southeastern Oklahoma as a public water supply. Total phosphorus, total nitrogen, and suspended sediments from agricultural runoff and discharges from wastewater treatment plants and other sources have degraded water quality in the lake. As lake-water quality has degraded, water-treatment...

Description of landscape features, summary of existing hydrologic data, and identification of data gaps for the Osage Nation, northeastern Oklahoma, 1890-2012
The Osage Nation of northeastern Oklahoma, conterminous with Osage County, is characterized by gently rolling uplands and incised stream valleys that have downcut into underlying sedimentary rock units of Pennsylvanian through Permian age. Cattle ranching and petroleum and natural-gas extraction are the principal land uses in this rural area....

Quality of groundwater in the Denver Basin aquifer system, Colorado, 2003-5
Groundwater resources from alluvial and bedrock aquifers of the Denver Basin are critical for municipal, domestic, and agricultural uses in Colorado along the eastern front of the Rocky Mountains. Rapid and widespread urban development, primarily along the western boundary of the Denver Basin, has approximately doubled the population since about...

A multiphased approach to groundwater investigations for the Edwards-Trinity and related aquifers in the Pecos County region, Texas
The Edwards-Trinity aquifer is a vital groundwater resource for agricultural, industrial, and public supply uses in the Pecos County region of western Texas. Resource managers would like to understand the future availability of water in the Edwards-Trinity aquifer in the Pecos County region and the effects of the possible increase or temporal...
Thomas, Jonathan V. Adaptations of indigenous bacteria to fuel contamination in karst aquifers in south-central Kentucky
The karst aquifer systems in southern Kentucky can be dynamic and quick to change. Microorganisms that live in these unpredictable aquifers are constantly faced with environmental changes. Their survival depends upon adaptations to changes in water chemistry, taking advantage of positive stimuli and avoiding negative environmental conditions. The...

USGS Responds to Near Record Flooding in Central Texas
USGS scientist Monica Langhorst measures gage height with a wire weight at Onion Creek at U.S. Highway 183 in Austin, TX.
USGS Responds to Near Record Flooding in Central Texas
USGS scientist Mark Warzecha makes a streamflow measurement with Acoustic Doppler Current Profiler downstream of a USGS streamgage station on the Blanco River at Interstate 35. The streamgage is not currently accessible, so a measurement is being made at the safest downstream location.
Water-level Change in the High Plains Aquifer System
In 1986, Congress directed the USGS to regularly report groundwater-level changes in the High Plains aquifer system. To comply with this directive, the USGS compares water levels measured every two years. By measuring water levels across the entire aquifer in one year, measurements made two years later enable calculation of changes over time. Measured water levels from
Climate, Water Quality, Toxic Blooms of Golden Alga in Texas
This webinar, Climate, Water Quality, Toxic Blooms of Golden Alga in Texas, was presented by Reynaldo Patino from the USGS Texas Cooperative Fish and Wildlife Research Unit.

Nitrate and tritium concentrations in ground-water samples collected this year by the U.S. Geological Survey from the High Plains aquifer in western Oklahoma indicate that water may be seeping from the land surface to the water table within the span of a few decades.
Wildfires have long played a key role in structuring ecosystems and plant communities in the southeastern United States. From the coastal prairie of Texas and Louisiana to the marshes and pinelands of Florida, many native species have adapted to a natural regime of frequent wildfire caused by lightning strikes.
Scientists from the U.S. Geological Survey (USGS) in Texas are working with local, state and federal officials to provide near real-time flood data in the wake of Hurricane Bret to emergency managers and others who then use the data to make decisions on evacuations and water management.
Nutrients from the Mississippi River Basin are believed to be responsible, at least in part, for the large hypoxic zone that develops on the Louisiana-Texas shelf in the Gulf of Mexico each summer, according to Don Goolsby, a hydrologist with the U.S.Geological Survey in Denver, Colo.
After enduring a summer full of sweltering temperatures, tropical storms, and floods, 20 inches of rain suddenly fell in areas of south central and eastern Texas this past week causing weather turmoil once again. Flooding from these rains has teams of scientists from the U.S. Geological Survey (USGS) mobilized to take water level and discharge measurements at rain-swollen streams.
U.S. Geological Survey (USGS) scientist, Katherine Kendall, will be awarded the National Park Service’s Natural Resource Research Award on September 28, at the Service’s annual Natural Resources Stewardship and Science Meeting in Austin, Texas.
A 5-year study of water quality in the Rio Grande Valley, from its headwaters in Colorado to near El Paso, Texas, has been completed by the U.S. Geological Survey (USGS). The study focused on ground water in the flood plain of the Rio Grande and surface water in the Rio Grande and selected tributaries.
The gasoline additive MTBE (methyl tert-butyl ether) was detected in some urban stormwater samples collected in 16 cities and metropolitan areas by the U.S. Geological Survey, but all detections of MTBE were less than the lower limit of the U.S. Environmental Protection Agency’s draft lifetime health advisory for drinking water.
