Hamburg, Iowa (image) NASA/Goddard Space Flight Center Caption In the spring of 2011, heavy rains and snow pack resulted in record releases from dams in Montana and the Dakotas, and near-record flooding along parts of the Missouri River. One especially hard-hit community was Hamburg, Iowa, where levee failure in early June caused extensive flooding and the evacuation of many homes. By late June, the US Army Corps of Engineers had rebuilt the levees and Hamburg was protected from additional flooding. This image acquired on Aug. 2, 2011, was taken by the Enhanced Thematic Mapper Plus on Landsat 7.
