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.
On September 19, the day after Hurricane Fiona made landfall near Punta Tocón, members of the U.S. Army Corps of Engineers, Walla Walla District Planning and Response Team (PRT) boarded a plane in Atlanta and flew to Puerto Rico. The team landed in San Juan at 8 p.m., on a mission to install generators and provide temporary emergency power to the island.
“I’ve always thought that the U.S. Army Corps of Engineers was all about hydropower. I didn’t think there was too much to it.”
The Mill Creek Channel is getting an update.
The Walla Walla District constructs, operates, maintains, and secures multipurpose infrastructure to energize the economy, reduce flood risk, and serve as stewards of water resources for the Snake River Basin and the Nation.
