Historic Sites and Points of Interest in Yuba County
A marker reads:
In 1895 pumps were installed at the confluence of the Yuba and Feather Rivers to protect the City of Marysville from the danger of flooding.
These pumps with a capacity to pump 18,265 gallons per minute, helped to keep Marysville dry during the Great Floods of 1955.
