Of all the RV parks and campgrounds in which we have stayed over the past 55 months, Padre Dam's Santee Lakes Recreation Preserve is one of the most interesting.
Lakes 1-5 are for day use fishing (catfish, rainbow trout, bass, and bluegill), while lakes 6-7 are for registered campers.
So far, the appearance of the grounds and the recreational activities on the lakes seem typical of a larger campground.
"We treat the sewage to stringent “Title 22” standards. How clean is it? California's standards for recycled water are the benchmarks in the United States and the world, and they allow for full body contact, such as swimming or waterskiing, where accidental ingestion is assumed" (http://www.santeelakes.com/sustainability.html#solar).
Truly, a most unusual RV park.
