A new assessment of channel bed erosion near 13 highway bridges in the greater St. Louis, Missouri, area is now available in an online report from the U.S. Geological Survey, produced in cooperation with the Missouri Department of Transportation.
Field training on well inventory and collection of water-level data at a non-flowing well near Yeghegnavan, Armenia, near the Armenia/Turkey/Iran border. Mt. Ararat is in background.
The growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin of Armenia. The USGS is working with...
The growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin of Armenia. The USGS is working with partners, including USAID, to develop scientific tools for water-resource managers to understand and predict consequences of management decisions in Armenia.
Mark Anderson, Director of the USGS South Dakota Water Science Center, demonstrates how to collect a stable isotope sample from a flowing well near Sis, Armenia.

In this image, a helicopter towing a large, cylindrical sensor makes low-level flights as part of a USGS remote geophysical survey, which collects data about underground geology. The scientific system, called Resolve, is operated by CGG Canada Services, Ltd.
This sensor, called a bird, is tethered to a helicopter during USGS geophysical surveys. As the helicopter flies low over specific areas, the bird transmits electromagnetic waves deep into the ground to measure the below-surface physical properties. This scientific system is called Resolve and is operated by CGG Canada Servives, Ltd. The bird pictured here was used for a...
Imagery from temperature-sensing cameras showing bats in hibernation. This new footage suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada. Locations: Gap Cave,125 Cumberland Gap National...
Some shallow-groundwater wells next to or downhill from Orange County agricultural fields treated with bio-based fertilizers have nitrate levels above Environmental Protection Agency standards set for public water supplies, according to a new U.S. Geological Survey report.
Media and the public are invited to attend a free meeting and field trips about South Dakota water issues on April 15 and 16 in Rapid City.
The U.S. Geological Survey awarded a $9.7 million contract to Crittenden Construction out of Alpena, Michigan, on March 5 for the construction and renovation of the USGS Great Lakes Science Center Hammond Bay Biological Station near Millersburg, Michigan. The renovation is a joint effort between the USGS and the Great Lakes Fishery Commission.
New and improved science tools can help managers and researchers evaluate current threats and develop management strategies to protect and restore the valuable Great Lakes ecosystem.
The U.S. Geological Survey has released a new report detailing changes of groundwater levels in the High Plains Aquifer. The report presents water-level change data in the aquifer for two separate periods: from 1950 – the time prior to significant groundwater irrigation development – to 2013, and 2011 to 2013.
Climate change could lengthen the growing season, make soil drier and decrease winter snowpack in the Lake Michigan Basin by the turn of the century, among other hydrological effects.
Scientists and technicians from the U.S. Geological Survey are conducting flood measurements in four different locations in the Lincoln and Omaha metropolitan areas in response to the high flows produced by the heavy rains over the last 24 hours.
Above normal precipitation in the Heart, Knife and Green River Basins of North Dakota led to record-breaking streamflows at several U.S. Geological Survey streamgages this past August.
The U.S. Geological Survey will celebrate the newest addition to its fleet of large research vessels in a traditional Christening and commissioning ceremony at the Lake Ontario Event and Conference Center in Oswego, New York, on Wednesday, August 6.
Streamflow in the eastern portions of the Missouri River watershed has increased over the past 52 years, whereas other parts have seen downward trends.
Insecticides similar to nicotine, known as neonicotinoids, were found commonly in streams throughout the Midwest, according to a new USGS study. This is the first broad-scale investigation of neonicotinoid insecticides in the Midwestern United States and one of the first conducted within the United States.
Asian carp eggs, including late-stage embryos nearly ready to hatch from the egg, were recently identified in samples collected by U.S. Geological Survey scientists in 2013 from the Upper Mississippi River as far north as Lynxville, Wisc.
