Drill rig to collect sediment samples on Lake Powell.

USGS scientists work with heavy machinery to collect sediment through the full thickness of the San Juan and Colorado River deltas.

Each one these blue dots represents a site where a storm-tide sensor bracket has been installed for the Gulf of Mexico pre-defined network. There are currently 85 brackets in Florida, 6 in Alabama, 3 in Mississippi, 18 in Louisiana and 26 in Texas, for a total of 138 bracketed sites. (Not all brackets will be used in all storms.)

The USGS creates a Flood Event Viewer for major flooding incidents, as a one-stop, interactive information source. On that website, viewers can click on each red dot (storm-tide sensor) to see details about it.

Chester County, Pennsylvania Observation Well CH 10. The well is 33.5 feet deep, and lies in the local Cockeysville Marble Aquifer, part of the larger Piedmont and Blue Ridge carbonate-rock National Aquifer. The well is relatively new to the Groundwater Quality Monitoring Network (GWMN) consisting of 27 wells distributed over 26 counties in Pennsylvania.
