About the Clarke Prize 

The Clarke Prize is named after Mrs. Athalie Richardson Irvine Clarke, a native Southern Californian who was active in both business and philanthropy.  As co-founder of the National Water Research Institute (NWRI), Mrs. Clarke recognized the vital importance of water and promoted better water science and technology. In honor of her vision, NWRI established the Clarke Prize in 1994 to recognize scientists who best exemplify Mrs. Clarke's dedication to finding solutions to the nation's water resource problems.


The Clarke Prize consists of a medallion and $50,000 prize.  It is one of only a dozen water prizes awarded worldwide, and has been distinguished as one of the most prestigious awards in the world.
