I'm not Warren, but I've been registered as a Civil Engineer in California for better than forty years, and I spent my whole professional career in the water resources field. I frankly find Mr. Menten's question ridiculous. Siltation of large reservoirs in the Sierra Nevada is not a significant problem. Anyone with any understanding of water resources engineering in California would realize that. The fact that he asked the question demonstrates either his utter ignorance of the field in which he chose to interject himself or his desire to obfuscate. -- Dave Powell dopowell@alumni.caltech.edu
