The impacts of climate change on water use and how the state can address them represent a significant change in the new 5-year update of the California Water Plan. Update 2018, released last week by the Department of Water Resources (DWR) in Sacramento, recommends actions to meet various important aspects of climate change. One of the priorities, improving integrated management of local watersheds, has been a focus of Zone 7 Water Agency in its role as manager of the Valley’s groundwater basin. As long ago as 20 years, the agency had been using the latest computerized research tools to gain a better picture of how the basin behaved, and best practices for its management.
