interactive Delta Island Flooding (With Repairs) Jul 1, 2008 This animation depicts how the Delta may change over time as a result of levee failures from earthquakes and floods. Islands that lie below sea level will flood after levee failures (becoming blue). Islands with sufficiently high land and asset values are repaired each time they are flooded (becoming white again). Other islands remain flooded.
interactive Delta Island Flooding (No Repairs) Jul 1, 2008 This animation depicts how the Delta may change over time as a result of levee failures from earthquakes and floods. Islands that lie below sea level will flood after levee failures (becoming blue). If islands are not repaired after flooding, the entire area is likely to be flooded by 2055.
Report Comparing Futures for the Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount ... Jul 17, 2008 For over 50 years, California has been pumping water through the Sacramento-San Joaquin Delta for extensive urban and agricultural uses around the state. Today, the Delta is ailing and in urgent need of a new management strategy. This report concludes that building a peripheral canal to carry water around the Delta is the most promising way to balance two critical policy goals: reviving a threatened ecosystem and ensuring a reliable, high-quality water supply for California.

blog post Caring About Delta Levees During a Drought By Jeffrey Mount Mar 26, 2015 When the sun is shining and our rivers are low, we tend to forget about the levees. This video—a simulation of what would happen if a severe earthquake hit the western Delta—is a reminder.
blog post Can We Capture More Water in the Delta? By Sarah Bardeen Jan 17, 2023 A massive amount of water is moving through the Sacramento–San Joaquin Delta in the wake of recent storms, and calls have risen from all quarters to capture more of this bounty. We spoke with PPIC Water Policy Center adjunct fellow Greg Gartrell to understand what’s preventing that—and to dispel the myth of “water wasted to the sea.”
blog post The High Cost of Fixing Levees By Jeffrey Mount Feb 23, 2017 The state’s levees are in poor shape. Upgrading them to avoid damaging floods will be very costly and will involve difficult trade-offs.
