Correct. No Stripers in El Cap.
Pyramid Lake and Lake Silverwood are supposed to have Stripers and look to be about 2.5 hr drive North from San Diego. Lake Cahuilla is North of the Salton Sea and about the same 2.5 drive, but in the heat will kill you before you catch a fish.
Here's a link I found with a snip of info pasted below.
Good fishing....... ;-)

Striper Fishing Lakes In California
The Colorado River lakes along the California-Arizona border are populated with striped bass. Before dams were built the river was a major spawning ground and many monster stripers have come from these waters.
In Central CA, Millerton Lake is the primary option for striper fishing. Southern CA has several options including Lake Cahuilla, Pyramid Lake and Lake Silverwood.
