 With much of the country broiling in a heat wave, some parts have imposed water rationing. Here in the arid deserts of eastern Washington, temperatures are expected to reach 110 degrees or more this week. The region has already been experiencing a drought, and even with the mighty Columbia River nearby, water rationing has begun. At the moment, it only applies to residential irrigation, but agriculture is a big industry here, and hot temperatures combined with limited water could be devastating to local crops.
