Assessment of Groundwater and Quality: Cedar River Alluvium, Cedar Rapids, Iowa Period of Project: Since 1992 Project Managers: Shannon Meppelink & Emilia Bristow Study Area: Linn County Cooperating Agency: City of Cedar Rapids (Water Division)

Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."

U.S. Geological Survey (USGS) scientists conducted the first statewide assessment of antibiotics, antibiotic resistant bacteria (ARB), and antibiotic resistant genes (ARGs) in streams (water column and bed sediment samples) across Iowa. Results indicated that ARB and ARGs were prevalent, and a combination of watershed characteristics (such as land use, livestock population, and human population)...

The U.S. Geological Survey (USGS) is conducting an Airborne ElectroMagnetic (AEM) Survey starting in late January 2023 and lasting three to four weeks. A helicopter towing a large hoop from a cable will begin making low-level flights over the Illinois River Basin, covering much of central Illinois and parts of northwest Indiana.

Surface water bodies in Cook County are used for stormwater detention, domestic and industrial uses, recreation, and commercial navigation. However, the bathymetry (elevation of the bottom surface) of most water bodies in Cook County has not been measured or mapped comprehensively. Similarly, water quality in most of these water bodies is unknown.

FEQ is a computer model for simulation of one-dimensional unsteady flow in open channels and through control structures. The structure of the program is designed to follow the structure of a stream system and provide maximum generality and flexibility. FEQ can be applied to simulate a wide range of stream configurations including loops and lateral-inflow conditions. Special features such as...

To monitor fish movement in selected rivers, the USGS has installed near real-time receivers for fish tags. These receivers detect the presence of acoustic tags that have been surgically implanted into a variety of fish species. The tag detection data can provide information about how far fish are moving in a river system, changes in fish population distribution, and, when viewed with flow and...

Scientists wanted to find out if trees can serve as indicators for vapor intrusion. What can trees tell us about the air we breathe at home? Science Journal Kids - Cutting edge peer-reviewed science research adapted for students

We have installed webcams at a number of locations in the Central Midwest Water Science Center to allow you to view the current conditions. Some of the cameras allow users to temporarily control the tilt, pan, and zoom. During periods of flooding the Central Midwest Water Science Center may take control of the camera.
