California drought, visualized with open data

USGS News release: ” A newly released interactive California Drought visualization website aims to provide the public with atlas-like, state-wide coverage of the drought and a timeline of its impacts on water resources. The U.S. Geological Survey developed the interactive website as part of the federal government’s Open Water Data Initiative. The drought visualization page features high-tech graphics that illustrate the effect of drought on regional reservoir storage from 2011-2014. For the visualization, drought data are integrated through space and time with maps and plots of reservoir storage. Reservoir levels can be seen to respond to seasonal drivers in each year. However, available water decreases overall as the drought persists. The connection between snowpack and reservoir levels is also displayed interactively. Current streamflow collected at USGS gaging stations is graphed relative to historic averages. Additionally, California’s water use profile is summarized. California has been experiencing one of its most severe drought in over a century, and 2013 was the driest calendar year in the state’s 119-year recorded history. In January, California Governor, Jerry Brown, declared a State of Emergency to help officials manage the drought. “USGS is determined to provide managers and residents with timely and meaningful data to help decision making and planning for the state’s water resources,” said Nate Booth, chief of USGS Water Information. “The drought affects streamflow across the state, which leads to reduced reservoir replenishment as well as groundwater depletion.” White House open data policies continue to provide opportunities for innovation at the nexus between water resource management and information technology. The Open Water Data Initiative promotes these goals with an initial objective of presenting valuable water data in a more user friendly, easily accessible format.”

  • “The State of California is experiencing one of the most severe droughts on record, which has implications for citizens of California and beyond. Many State, Federal, and Tribal agencies make routine observations of the water cycle. This website graphically visualizes these data to help understand the effect of drought on rivers, streams, lakes, and reservoirs. Below, learn more about water use and changes in the water cycle due to the current drought in California. The data presented here are drawn from free and publicly accessible sources. In addition, the analytical, graphical, and software tools used are open-source and available for public re-use. For more information about drought and science-based decision making in California, visit the USGS California Water Science Center webpage. Firefox is recommended for the best viewing experience.”
