On Nov. 5 (Wednesday), geology professor Jeffrey Mount discusses recent events shaping the future of the Sacramento-San Joaquin Delta, the hub of California's water supply system, providing water to more than 25 million Californians and over three million acres of irrigated agriculture. This landscape is at a tipping point, with a variety of physical and economic factors aligning to transform it.

Mount's presentation is part of the JMIE speaker series on Environmental Solutions: Lenses on the Delta and the Geography Graduate Group's History of California's Landscapes Distinguished Speakers Series.

It is free and open to the public, and will be held from 5:10 p.m. to 6:30 p.m. in Room 1150 of Hart Hall. Information: http://johnmuir.ucdavis.edu/news/jmie_events.html.
