History of the Salinity Lab
headline bar
 

In 1947,
our Laboratory
was on the
other side of town

From 1947 to 1995, the United States Salinity Laboratory (USSL) occupied 10 acres south of Mount Rubidoux in central Riverside. The Facility was housed in seven buildings containing approximately 11 laboratories, two large greenhouses, a rhizotron, environmental chambers, lysimeters, plant culture beds, outdoor plots, and constant temperature rooms.
 
Most of the research could be accomplished at Riverside, but investigations requiring full-scale field situations were undertaken in areas such as the San Joaquin and Imperial Valleys of California, the Wellton Mohawk Irrigation District in Arizona, and Grand Valley in Colorado. The original Rubidoux Laboratory building is now occupied by the University of California Water Resources Center.   small image of old Lab
