In 1931, a torrent of brown water roared down Mill Creek, with water levels rising at a rate of one foot per hour. The water escaped the confines of the riverbanks and rushed through the City of Walla Walla, destroying homes, roads and bridges. Born in the wake of this disastrous event, the Mill Creek Project now stands to protect the city from floods like this.

The City of Walla Walla, which means the “place of many waters,” experienced regular flooding in the past including Mill Creek. In 1931, heavy rainfall caused Mill Creek to rise, resulting in a devastating flood. This flood prompted the Walla Walla Chamber of Commerce, to lobby the U.S. Congress for flood protection and the project was authorized by the Flood Control Act of 1938. Construction of the dam and its associated works was completed in 1942 followed by the paving of the Mill Creek Channel through the City of Walla Walla that was completed in 1948. Since its construction, the Mill Creek Project has prevented at least $300 million in potential flood damages.
