April 27, 2011, flooding of the Souris (Mouse) River near Westhope, North Dakota. The small building is the U.S. Geological Survey gage house and is normally on the river bank and raised so that one needs to take stairs up to get into the gage house. There is also an access road next to the gage house and electrical pole.
