Subsidence Lowers Friant–Kern Canal by 5 Inches in 5 Months
LINDSAY, CALIFORNIA - When officials with the Friant Water Authority (FWA) did an initial survey in April 2017 to measure subsidence along the Friant-Kern Canal, they expected to see impacts from the recent drought. What they measured in some places was a nearly three foot drop in the canal elevation.
Even with last winter’s record breaking rain, snowfall and runoff, they assumed the discouraging trend would continue. What they found in early August when they resurveyed portions of the canal confirmed their fears. Since April the canal has dropped another 5 inches in one particularly hard hit location.
“These findings are not entirely unexpected,” commented Doug DeFlitch, Chief Operating Officer for FWA. “Subsidence is a long-term challenge for the Friant Division, and will not be remedied after one year of good rain.”
Jason Phillips, Chief Executive Officer for FWA added, “The continuing subsidence issue is why FWA is exploring possible funding mechanisms for bringing the Friant-Kern Canal back to its designed operational potential. A fully functioning canal will help achieve the groundwater/surface water balance the Friant-Kern Canal was designed to maintain, and lessen the impacts of subsidence.”
Land subsidence is the gradual sinking of an area of land which occurs more dramatically in the region when groundwater is over drafted. Water that is removed from very fine clay-like pore space in the subsurface no longer has its internal strength and over time compresses and the surface of the land drops. During the drought when surface water supplies were limited or unavailable, regional farmers, cities and others relying on surface water supplies turned to groundwater. The resulting subsidence forced cuts in water deliveries to parts of the canal system during critical times this past summer.
The Friant Division was designed to bring stability to the San Joaquin Valley’s groundwater supply, which was threatened at the beginning of the 1920s by decades of groundwater pumping. The Friant Division’s two canals – the Friant-Kern and the Madera – source high-quality surface water from the San Joaquin River that supports crops, cities, and groundwater recharge. This investment to establish the Friant Division has paid off by providing stable surface and groundwater supplies that created and sustain a world-class agricultural sector that in turn supports numerous communities and businesses.
The Friant-Kern Canal is a gravity-fed facility and currently does not rely on pumps to move water. Subsidence disrupts the natural grade line, which negatively affects the canal’s ability to convey water. As the surface expression of land subsidence continues to occur, the canal will continue to lose capacity. Current estimates put those reductions at nearly 60% of design.
FWA is a joint-powers authority formed in 2004 by a majority of the water agencies receiving water from the Friant Division of the Central Valley Project. Its primary purposes are to operate and maintain the Friant-Kern Canal and to serve the information and representation needs of its member agencies.

Friant Water Authority Says Good-Bye to Director Georgeanne White
Visalia, Calif. – The September 28th, 2017 Friant Water Authority Board of Directors meeting marked the last for Georgeanne White. Ms. White is leaving the City of Fresno in October after over 17 years with the city, including serving as Chief of Staff for Fresno Mayors Alan Autry and Ashley Swearengin, and is currently the Assistant Director of Public Utilities for Administration and Water Policy. She served as the designated alternate director for then Fresno Mayor Swearengin in 2014, and currently serves in that role for Mayor Lee Brand. In 2017, she was elected to leadership roles on the FWA board, serving as the Board’s Secretary/Treasurer and the chair of the Finance and Human Resources sub-committees.
FWA Board Chairman Kent Stephens noted, “Georgeanne brought a valuable perspective, energy and knowledge that has made Friant a better organization. She will be missed, and we wish her the very best in her future endeavors.”
Ms. White’s successor to represent the City of Fresno on the FWA Board will be Tim Orman. Mr. Orman serves as Chief of Staff to Mayor Brand and is the owner of Orman Communications. …….
