Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see

Sediment Acoustics- Molly Wood

Acoustic instruments are increasingly being used to measure suspended-sediment concentration (SSC) in fluvial environments. The USGS Office of Surface Water, USGS Sediment Acoustics Leadership Team, and the Federal Interagency Sedimentation Project are developing standardized methods and software for estimating SSC from acoustic backscatter from acoustic Doppler current profilers (ADCPs).

Large-scale Particle Image Velocimetry (LSPIV) for Measuring Complex Flows- Frank Engel

Valuable hydraulic data such as water levels, estimates of discharge, inundated areas, etc., can be extracted from photos and movies taken by engineers and scientists that can be used to help improve the analysis and understanding of flood hazards.

Fish Telemetry

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...

River WebCams for the Central Midwest Water Science Center (Illinois, Iowa, and Missouri)

We have installed webcams at a number of locations in the Central Midwest Water Science Center to allow you to view, in real time, 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.

Assessing the uncertainty in model estimated streamflows: A case study using watersheds and rain gage network in Chicago metropolitan area- David T. Soong

The intern will benefit through professional growth gained by academic training in hydrologic science, statistical analysis, and numerical modeling. The intern will also benefit from mentoring opportunities with the PIs and other USGS scientists; with academic professionals at University of Illinois–Urbana, and potential co-authorship on one or more scientific publications.

Assessment of historical recruitment of grass carp in the Sandusky River- David T. Soong

This is an interdisciplinary project linking stream ecology and hydraulic engineering. The intern will join a team to conduct scientific research on a “hot-topic problem” that has gained national attention and will benefit by gaining exposure to a real-world problem that perhaps cannot be found in textbooks.
