Could a mass evacuation like the one in Oroville happen here in San Diego? The city says no, that all the dams around our area are safe. The Miramar Dam is a very popular recreation area. There are runners, bicyclists all out enjoying the lake and the view. What all these people are exercising on is actually an earthen dam. “It’s very critical for our water supply here in the San Diego region,” says Halla Razak, Director of the San Diego Public Utility Department.
