The US is only part of the problem as the UK, and parts of Europe, are experiencing water shortages as well. Pictures of bridges over died up river beds are surfacing there as well. Even the shallow draft boats that cruise the Rhine and other rivers are looking at their schedules. Boats used for shipping goods are having to consider load sizes so that they can use the waterways. There is talk of restricting water usage throughout Europe because of the lack of rain.
Arizona, Utah, New Mexico and Texas are having heat and water problems similar to California. Utah's Great Salt Lake and Powell Lake are at historic lows. Bodies are being found in dried up lake beds with some encased in cement or barrels. Maybe they will finally locate Jimmy Hoffa.
