Coralville Lake 3 Star


Coralville Lake

Coralville Lake was authorized by the Flood Control Act of 1938 as a means of moderating stream flows on the Iowa River.

Construction of the dam began in 1949, was delayed by the Korean Conflict and was finally completed in 1958. The US Army Corps of Engineers has a tradition of naming a dam or lake after the first town downstream from the dam. The city of Coralville is the first town downstream from the dam on the Iowa River, therefore the name, Coralville Lake. The town of Coralville acquired its name from the coral formations found while digging a foundation for a mill in 1866. These formations suggest that this site was once a shallow, open sea environment. Scientists estimate that this condition existed here approximately 350 million years ago.
