  availability of external supplies concern over
  the long-term stability of the existing surface
  water supplies.
• Restoring Ecosystem Restore the ecosystem along
  the San Joaquin River below Friant Dam while
  maintaining water supply reliability for other
  purposes.
• Integrity of Sacramento-San Joaquin levee system
• Groundwater
