AnalogyAnalogy

Jeremiah 2:13 “For my people have committed two evils: They have forsaken Me, the fountain of living waters, to hew for themselves cisterns, broken cisterns that can hold no water”. Cistern as an analogy to the bearer of God’s spirit God’s spirit in water – what would baptism be without water? What would life be without water? An earthkeeper’s perspective is Man’s relationship with nature as well as in relation to God. I use cistern as an analogy to California’s great water system, the CVP/SWP

San Joaquin River used as water supply (Friant Dam, Madera Canal, Friant-Kern Canal)

Sacramento River used to resist seawater intrusion during incoming tides (Shasta and Folsom dams) and to freshen San Joaquin water (Delta Cross Channel).

Mitigation water to senior water rights holders (Delta Mendota Canal)

Freshwater diversion site for Pittsburg and Antioch (Contra Costa Canal)

CVP NEVER designed to use Sacramento River water as water supply.

(SWP uses Feather River and relies upon through Delta water conveyance.)

What you can doWhat you can do

Remember Proposition 9 in 1982 (Both sides lied).

Gather information and decide (you can do this!).Is protecting California’s economy important?

Should ecosystems be restored as we fix the water system? (Be not against nature)

Cost will be $3 billion and up. Spend it well.
