Tim Quinn, executive director of the Association of California Water Agencies, is scheduled Monday, Feb. 4, to talk about California's challenges in managing water reliability and Delta ecosystem health "coequally," as mandated by the state Delta Reform Act of 2009.

The 4:10 pm to 5:30 pm event at 1227 Haring is the fourth in the Center's California Water Policy speakers series this winter.

Quinn leads the largest water organization of its kind in the nation. The association's 450 public water agency members are responsible for about 90 percent of the water delivered in California. Videos of previous speakers are available on iTunesU
