USGS invasive species science in the Midwest Region is focused on early detection, risk assessment and development of new management control tools and strategies to prevent spread of invasives including Asian carp, invasive mussels, and Phragmites (an invasive wetland plant) in areas including Great Lakes and the Mississippi and Missouri River basins.
Information on the Bakken Formation in the Williston Basin in the north central part of the United States and associated studies pertaining to the oil and gas development in western North Dakota and in nearby states.
The USGS National Water-Use Information Program collects data about the quantities of water withdrawn for specific uses: public supply, domestic, industrial, mining, thermoelectric power, irrigation, livestock, and aquaculture.
The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine if fungi that live within the Phragmites are enabling the plant to take over habitat used by...
Pallid sturgeon free embryo at approximately 10 days post-hatch, approximately 19-20 mm (about 0.77 of an inch) in length.
Lake trout historically supported the most valuable freshwater commercial fisheries in North America, but their populations crashed in parts of the Great Lakes during the 1950s and 1960s due to overfishing and invasive species.
A 31-mm sturgeon captured in the Missouri River near Williston, North Dakota, on July 8 using a beam trawl. Sampling efforts occurred in support of a recent inter-agency collaborative drift experiment involving 700,000 sturgeon embryos. This sturgeon will be genetically test to see if it is from those used for the experiment.
Student Contractor Garrett Cook processes a drift sample collected on June 27 shortly after the free embryos and beads were released. Note the small cluster of pallid sturgeon free embryos and green beads in the lower portion of the sorting tray. These embryos and beads were elements of the Upper Missouri River drift experiment.
Highest concentrations found in Iowa, Minnesota and Illinois.
A graduate student at The University of Toledo is the first researcher to find direct proof of grass carp, a type of invasive Asian carp, spawning in a Great Lakes tributary. This research was conducted as a follow-up to U.S. Geological Survey findings in 2013 that indicated four young grass carp taken from the Sandusky River were the result of natural reproduction.
Past fireworks displays are the probable cause of elevated concentrations of a contaminant called perchlorate in groundwater and surface water within Mount Rushmore National Memorial, according to a recent U.S. Geological Survey report.
South Dakota-based scientists from the U.S. Geological Survey are helping to restore a depleted aquifer and build in-country expertise for managing groundwater in the Ararat Basin of Armenia.
The Souris, or Mouse, River Basin is currently in a wet climate period and will be at high flood risk for some time, according to a scientific model published today by the U.S. Geological Survey.
U.S. Geological Survey field crews are measuring near-historic flooding on rivers and streams across Illinois.
Increased precipitation is the primary cause of rising streamflow in many eastern South Dakota streams, according to arecent U.S. Geological Survey report.
Rapid predictions of harmful algal blooms, or large growths of toxin-producing bacteria in water, can help prevent recreationalists from getting sick at Ohio lakes, according to a new U.S. Geological Survey report.
U.S. Geological Survey field crews are measuring flooding on rivers and streams across central and southern Missouri.
U.S. Geological Survey scientists will conduct a high-resolution airborne survey to study the rock layers under a region of northeastern Iowa, starting Monday, October 19, and lasting into November.
The City of Sioux Falls and the United States Geological Survey (USGS) are conducting a state-of-the-art groundwater survey this fall. Beginning this week, CGG Canada Services, who is under contract with the City, will begin flying a helicopter over the Big Sioux Aquifer to collect, record, and map its geophysical measurements.
