USGS personnel (5'8") stands next to ice formation at Big Muddy Creek. Flow is 6.45  cubic feet per second.

USGS hydrologic technicians Tyler Meyer and Jesse Rigge document the river stage and ensure that the streamgage on the James River at Huron, SD is working properly. A streamflow measurement of 17,500 cubic feet per second was made during the site visit.

North Dakota Discovery Farms Embden waterway sites 1 and 2 located southeast Cass County about 8 miles south of Embden, North Dakota.

North Dakota Discovery Farms waterway sites 1 & 2 located in southeast Cass County about 8 miles south of Embden, North Dakota. In 2009, Embden became the third farm in the North Dakota Discovery Farms project. Farm is located about 1/2 mile south of data shelters. Embden 1 is a surace-water site.

This image and associated video captures the breakup of ice cover on the Skunk River at Augusta, Iowa, on February 17, 2011, at approximately 3:00 p.m. local time. The river stage at the time was 14.50 feet (elevation 1,179.41 feet NGVD29).

Increase flow in the Des Lacs River and warmer temperatures probably caused instability in the area of the ice spikes causing them to disappear.

This adolescent chick, hatched and raised at the USGS Patuxent Wildlife Research Center, is one of ten whooping cranes being released in Louisiana in February 2011. It is a milestone for the state and for the birds, which have not lived in the state since the 1950s.
