Senators Dianne Feinstein (D-Calif.), Cory Gardner (R-Colo.), Martha McSally (R-Ariz.) and Kyrsten Sinema (D-Ariz.) today introduced the bipartisan Drought Resiliency and Water Supply Infrastructure Act, a bill to improve the nation’s water supply and drought resiliency. The legislation builds on Senator Feinstein’s 2016 California drought legislation that was included in the Water Infrastructure Improvements for the Nation (WIIN) Act. “The effects of climate change are here to stay, and one enormous effect on the West is more – and more severe – droughts,” said Senator Feinstein. “As California continues to recover from a historic drought, the Lawrence Berkeley National Laboratory now estimates that the Sierra snowpack, a primary source of water for California, will decrease by 79 percent by the end of the century.
