bigpigeon.us webpage Pott. Co. > Early History > Missouri River, updated by RAC 11 Mar 2020.
Under development 11 March 2020.
The accompanying map shows the Missouri River, the Missouri River basin, and the major Missouri River tributaries.

Pottawattamie County is in western Iowa across the Missouri River from Omaha, Nebraska.
The Missouri River Basin
The Missouri River Basin

In the 20th century, the original wild and meandering Missouri River was channelized aong the Iowa-Nebraska border, with levees built to protect the adjoining floodplains. The wide floodplain at the west edge of Council bluffs was developed.

During the flood of 2019, most area levees broke, inundated thousands of acres of farmland. North of Council Bluffs, land remained under water for months.

Because of levees, between Council Bluffs and Omaha the Missouri River flows through a narrow channel. Fortunately, in floods in 1952, 2011, and 2019, the Council Bluffs levee held. If it had broken during the massive 2011 or 2019 floods, many thousands would have been homeless, with dollar property losses in the billions.
