Sec. Salazar continues the time-honored tradition of promising California hydrological miracles

Mike Tougher has a good article in the San Jose Mercury News about Interior Secretary Salazar's comments on pumping Delta water to Central and Southern California.

Last year, when I pointed out that Meg Whitman (remember when she ran for Governor?) promised more water, I gave her the benefit of the doubt and chalked it up to the pressures of a live debate (I'm sure I'd look like a complete moron in a live debate, so I'm always judging those events nicely).  Secretary Salazar, when taking questions before the Commonwealth Club, might also get the benefit of the doubt.  It was a live, well-respected audience.

But the comments Mr. Tougher reports show a man flirting with serious conflicts with physics.  And believe me, physics always wins.

From Mr. Tougher's report:  "Salazar said building a new aqueduct around the Delta might increase the flexibility of water operations in such a way that it could lead to more water deliveries."

The Delta needs x amount of fresh water each year.  We aren't sure what x is, yet, but we know that in a typical year it is more than it now gets.  If freshwater is diverted from the Delta, it will suffer an ecological decline.

Mr. Salazar later visited the new fish screens put up to protect fish from the South Delta pumps.  Unfortunately, what Mr. Tougher failed to note is that the sucking up of fish into the pumps is only one of the ways they impact endangered and threatened species.  Their overall impacts on the flow of water through the Delta also kills fish by confusing them and sucking them into predator pits. 

But never forget that removing actual habitat (i.e., through a peripheral canal) is not the cure for pump impacts on tides and flows.  The single greatest ecological and economic benefits for both the Delta and the rest of the Central Valley would come from farming the Westlands for solar power.  

Physics can be our friend.
