Exhibition Spotlight: A Century of IIHR Research on the Mississippi River (Part 2)
ZoomIIHR’s work on the Mississippi River dates to the 1920s, when researchers set out to measure the flow of the river just upstream of the Keokuk Dam (now part of Lock and Dam No. 19) at Keokuk, Iowa. IIHR Director Floyd Nagler also modeled the dam’s spillways for the Mississippi River Power Company.
