Water interests argue new state dam proposals

Thirty years ago, a chunk of chain, an eyebolt and Mark Dubois helped end the era of big dam building in California.

As California grapples with an aging water-delivery network, growing population, worsening water quality, a drought and the potentially far-reaching effects of global climate change, dams are again on the table. Last month Schwarzenegger insisted he would not sign off on any major overhaul of the water system without money for new dams and reservoirs. The governor has the support of conservatives and the vast Central Valley, where many farmers are convinced that new, man-made lakes will help offset dry spells and ease the federal rulings that have cut water pumped through the ailing Sacramento-San Joaquin River Delta.
