This bill reauthorizes through FY2033 the Bureau of Reclamation's water cycle, drought, and climate change program, which Reclamation implements through the WaterSMART Basin Study Program. This program is authorized to coordinate with other appropriate agencies to assess global climate change with respect to water resources in the eight major reclamation river basins in the western United States. The program must also ensure watershed and aquifer system strategies are developed to address potential water shortages, conflicts, and other impacts to water.
