California — without a doubt — has the most intricate and massive water storage and transfer system man has ever created. It is the largest, most productive, and most controversial water system in the world that harnesses nature using man’s ingenuity. At its northernmost reaches it captures the snow run-off of the Modoc Plateau — volcanic highlands in northeast California and southeast Oregon — that is drained by the Pit River, Snow blanketing the hills of the Modoc Plateau today will melt in the coming weeks and start a long journey in the form of water. The journey’s end for water — that makes it that far — are faucets and water taps in San Diego less than a mile from the border of Mexico.
