The left axis is a visualization of an ensemble of solutions (crosses and dashed lines) iteratively moving down gradient on an objective function surface (color flood) in 2-D parameters space, with the associated prior (gray) and posterior (blue) parameter marginal distributions shown on the two right stacked axes.

This USGS streamgage on Schantz Spring near Wescosville, Pennsylvania was partially submerged after floodwaters from Tropical Storm Isaias quickly rose and flooded the area. USGS crews arrived on scene August 4 to

Fisseha Mengistu, USGS hydrologic technician, uses a device that lowers a water sampler into the creek below to collect samples used for water quality testing. Experts will be able to use this data to track how Tropical Storm Isaias impacted water quality in the area. This work was done on Rock Creek in Washington, D.C. Real-time data for this water quality site is
