Harriet Strong

Hariet Russell Strong was born in Northern California in 1844. In later years she would come to be known as "The Walnut Queen" as a result of her cultivation of some of the largest walnut estates in Southern California. The success of her orchards was due to the skilful invention of an irrigation system that was based on a patented flood control/storage dam system. As Susan Casey notes, "the system was unique in that it incorporated a succession of dams that ensured safety in case of a break." Each dam section was structurally supported by the pressure of the water of the preceding dam. Water was regulated and controlled in a uniform fashion (Casey, p.30).
Harriet Strong received patents for several other inventions and was widely recognized in her own time as an engineer, entrepreneur and supporter of women's rights and water conservation.
