The Upper San Joaquin River Basin Storage Investigation is a feasibility study of new surface water storage that is being performed by the U.S. Department of the Interior’s Bureau of Reclamation.

The purpose of the investigation is to determine the type and extent of federal, state, and regional interests in a potential dam project in the upper San Joaquin River watershed to expand water storage capacity; improve water supply reliability and flexibility for agricultural, urban, and environmental uses; and enhance San Joaquin River water temperature and flow conditions to support anadromous fish restoration efforts


This investigation is one of five surface water storage studies recommended in the CALFED Bay-Delta Program Programmatic Environmental Impact Statement/Report Record of Decision of August 2000.

Reclamation released a Draft Feasibility Report in February 2014 that provides an in depth examination into the potential construction of a new dam and reservoir on the upper San Joaquin River, between Friant and Kerckoff dams. View the feasibility report available here.

A fact sheet on the overall investigation is available here.
