A wide shot of the current flow field, from the coastal plain up to the TEB vent. The current flow is still split into an eastern and western lobe on the coastal plain, entering the ocean along the eastern lobe (lower right). The area is scattered with small breakouts, several of which show up nicely in light grey.

Earlier this week, lava began erupting from a vent on the floor of Pu‘u ‘Ō‘ō crater. The mound on the right side of the photo is the vent producing lava flows, slowly filling the east side of the crater.

USGS hydrologist Brent Hanson is interviewed by media at the flooded Souris River in Foxholm, N.D., about 30 miles northwest of Minot. A flooded road can be seen in the background.

As the Souris River flooded during the early summer of 2011, it overcame levees in the city of Minot, N.D., causing about 11,000 people to evacuate their homes. The record-breaking flood crested on July 25 at over 26,000 cubic feet per second (cfs) and 24 feet - nearly 13 feet over flood stage - according to U.S.

USGS scientists measure streamflow on a tributary of the Souris River in Foxholm, N.D., about 30 miles northwest of Minot. The team is using an acoustic Doppler current profiler (ACDP) to measure streamflow.

The USGS Souris River at Foxholm, N.D. streamgage (center of photo) is half inundated by water about 30 miles northwest of Minot. This water channel, normally only about 30 feet wide, runs through a wildlife preserve.

Release of 80,000 cfs from Oahe Dam, near Pierre SD on May 27, 2011.  This is the largest release since Oahe Reservoir Filled in 1959.  Releases are expected to increase to 150,000 cfs before mid-June.
