That includes a program of state-required annual inspections and the use of remote electronic monitoring instruments that can detect changes in moisture levels or movement to keep an eye on conditions in the dam embankment. Theres more than one answer to that question. The worst-case scenario is modeled assuming the height of the dam wall becomes zero instantaneously for example, as might happen if there was an explosion due to sabotage. Water conditions near a dam Above the dam flow can pull swimmers in and drag them below the water level with such force they cant escape.

But crucially, the analysis found that because the top of the dam is 23 feet above Lake Chabot's maximum surface level, there would be no uncontrolled release of water. A major task of the RMS flood modeling team was to take disparate public levee data, which only accounts for a maximum of 20 percent of the nations flood defenses, together with the use of a proprietary stochastic modeling technique that accounts for the likely presence and standard of protection of defenses along the entire modeled river network. To understand EBMUDs confidence that a dam built within a quarter-mile of a dangerous fault will stand up to a violent shaking, lets take a look at how the dam was first built nearly 150 years ago and how its been maintained since.
