In the beginning there was water and land, rivers and floodplains. Now there are levees and dams, and centuries of history brought by the rivers dictating the fate of Sutter and Yuba counties. Knowing the history of the land, a reasonable person may wonder how — more than why — people have lived there for so long. A new exhibit at the Sutter County Museum delves into that answer, showing the history of floods and human intervention in the Yuba-Sutter area. … The museum’s new flood exhibit walks visitors through the evolution of the land surrounding the Sutter Buttes and extending past the Feather and Yuba rivers.
