In this year of record rainfall, billions of gallons of water are flowing to the ocean that – if only sufficient storage existed – could be stored for the drought that inevitably will return. If ever there were an argument for construction of Sites Reservoir to the west of the Sacramento River, this winter’s rain is it. The project is poised to get welcome support from Southern California. The Sacramento Bee’s Dale Kasler reported Thursday that the Southern California Metropolitan Water District is considering investing a modest sum, $1.5 million, to help plan for the $4.4 billion project in Glenn and Colusa counties.
