 Because the natural summit or border between the Kings River basin and the San Joaquin River's watershed, and the Kings River itself nearly intersect near Lemoore, a number of huge water works that control regional water flow are also located nearby.For example, in flood years the Kings River is diverted west into the so-called "North Fork Kings River," to Crescent Weir and related major levees eastward to the north-flowing Fresno Slough and to the sea, preventing a resurgence ("flooding") of Tulare Lake to the south.This "switch point" is located just north of Lemoore right off of Highway 41 and Elgin Ave at the New Island Weirs.
