Bonanza Spring Kenney Presentation

Geologist Miles Kenney presents findings from an in-depth study of Bonanza Spring to a panel of his peers. Kenney found that the supply of water to the spring is hydrologically disconnected from the groundwater system for the Cadiz Valley. The spring is separated from the Cadiz Valley by 11 miles and 1,100 feet elevation and would be unaffected by a plan to capture water in Cadiz that would otherwise be lost to evaporation.


Bonanza Spring Miles Kenney

Dr. Miles Kenney is a field geologist who studied rock formations around Bonanza Spring in the eastern Mojave Desert for several months in 2017. His study shows that the spring is fed by rainfall at upper elevations and would not be affected by pumping at the Cadiz Water Project, 11 miles away.

Bonanza Spring Overall

Bonanza Spring exists because of geologic formations that act as a dam, trapping rain runoff from surrounding hillsides. The water eventually seeps through fractures in the rock and forms the spring.

Bonanza Spring Peer Review

Dr. Miles Kenney explains his findings to a fellow scientist who reviewed the study. The group supports Kenney’s conclusion that the spring could not be impacted by the regulated conservation of groundwater at Cadiz.

Bonanza Spring Rocks

The hillsides around Bonanza Spring are comprised of crystalline rock and other non-porous formations that essentially trap runoff from surrounding hillsides. The trapped water eventually seeps through fractures in the rocks to form the spring.

Cadiz Agriculture

The 70-square-mile Cadiz Ranch is the agricultural arm of Cadiz Inc. and is supported by plentiful underground water supplies.  Careful management of groundwater resources has ensured the success of the farm, which grows lemons, grapes and other crops in the desert. The Cadiz Valley is 11 miles and an 1,100-foot drop in elevation from Bonanza Spring.
