The Water Sustainability Decision-Support Tool and Sustainability Indicators Catalog was created to support the California Water Plan Update 2013, as well as future Water Plans and other state plans. The tool and catalog were designed and the project led by Dr. Fraser Shilling, UC Davis. The site was programmed and organized by Dr. David Waetjen, and the indicators and analyses conducted by a combination of Susana Cardenas, Iara Lacher, Fraser Shilling, Marcelo Tognelli, and David Waetjen. Partial funding for the site came from the California Department of Water Resources and the US Environmental Protection Agency. Questions should be directed to Fraser Shilling at email@example.com.
