A Defining Moment in California Water May 22, 2017 Presentations & Multimedia “A Defining Moment in California Water” highlights the need for a more balanced and comprehensive approach to setting water quality objectives in the Bay-Delta watershed. The video shows the stark contrast between the State Water Resources Control Board’s “unimpaired flow” approach and ACWA’s policy statement on Bay-Delta Flow Requirements, which calls for “functional flows” and collaborative, voluntary settlements. While the State Water Board’s approach could lead to widespread fallowing of agricultural land and negatively affect water reliability for much of the state’s population, ACWA’s approach has proven successful in achieving positive ecological outcomes while maintaining water supply reliability.
