According to the California Water Science Center, the The Dust Bowl is the most famous environmental catastrophe in U.S. history, and although irresponsible farming practices and land mismanagement contributed to the disaster, the Dust Bowl—which coincided with the already devastating Great Depression—was essentially the result of drought. Above, Landsat imagery was used to estimate the change in surface area from August 2011 to August 2014 for two of California's largest reservoirs, Snowpack in California is the primary source of water to reservoirs that serve drinking water, agriculture, and hydroelectric needs.For any given year, less wintertime snowpack results in lower reservoir levels, and less water for consumptive use.In 2014, California received only a fraction of its normal precipitation and snow pack, with the State now facing three years of devastating drought (The current and historical streamflow in unregulated rivers and streams (those without upstream reservoirs or control structures) are shown in the graph.Current streamflow (y-axis) is plotted against the historical (since 1980) median streamflow (x-axis) for this day of year.
