He also noted that private sector partnerships in the Fourth Assessment are limited and are clearly an area for future growth. See the winning play. He concluded with several observations about water infrastructure and governance in California, including the lack of data on current water system operations, the highly fragmented institutions that oversee its operation, and the risk aversion characteristic of water managers (Haneman et al., 2016).

This motivated Sonoma Water to develop and implement forecast-informed reservoir operations at Lake Mendocino, and they have requested a major deviation from traditional flood control levels for the year 2019 with the goal of capturing and storing additional water without increasing flood risk. People are increasingly moving into areas near forests, known as the urban-wildland interface, that are inclined to burn.
