Delta urgency
Entire state faces an increasing threat from troubled waters

Wednesday, June 1, 2005

Management of the Sacramento-San Joaquin Delta appears to be on an unsustainable course. As this troubling truth begins to sink in, calls are mounting to ever-so-gingerly evaluate the options. Fortunately, the interest in tackling the many Delta issues is coming from many corners.

Assemblyman John Laird of Santa Cruz has a bill to launch a Delta study that is backed by the Sierra Club and a Silicon Valley business group. And the Association of California Water Agencies, in a recent "blueprint" for future water needs, singled out the Delta as needing a commission of experts to examine the vital estuary and water supply source for two-thirds of the state.

The levees that surround the many islands in the Delta are of particular concern to Laird's legislation, AB1200. Years of farming on these islands have exposed the peat soils, oxidizing them and lowering the elevation of the islands to the point that they're below the water level. Only the levees keep them dry. The levees are substandard and in disrepair. Funds to fix them are far short of what's necessary. When it comes to the levees, there's more fighting than fixing going on these days.

Were certain levees to fail on a cloudless summer day (as one did last year) or during a flood or an earthquake or due to rising sea levels, the Delta could quickly transform into a brackish, undrinkable soup. It's a scary scenario. The risks need to be better understood and quantified.

ACWA's laudable call for a "blue ribbon" panel is a tacit admission of the touchy politics. Inevitably any study of the Delta could eventually lead to examining how water is conveyed through the system. One option, long controversial, is to move water supplies not through the Delta but around it, through either a canal or pipeline system ‹ the so-called Peripheral Canal.

It's way too soon for political panicking or prejudging what experts may ultimately say about the Delta's problems and fixes. But if advice were to come from credible sources with no agendas other than the well-being of California, maybe the various Delta interests would listen.

And maybe somebody ‹ the Legislature, the governor, the interests themselves ‹ can agree that some fixes are less scary than the present course. When it comes to the Delta, knowledge isn't dangerous. Knowledge and leadership are necessary.
