Simple, pretty, well maintained county park
Stayed in space 10, a partial hookup with a view of the lake. They have full and partial hook up spaces and "primitive" tent only sites.
Partial hook up had water in camp and an electrical box with 2 kinds of shore power and a 2- 110 outlets for $29.
Ranger was nice, bathroom was clean, neighbors are close when it's full, but I was there off season. It's a San Diego county park, reserve through their website. You can't book online for same day camping, so check the county website for how many spaces are available then pay on site, cash or charge. There is a small store at the day use area (I didn't go in), and a boat launch. You can rent boats to go out on the lake. No swimming allowed.
There is a mating pair of bald eagles near the dam that has 2 growing babies. Ask the ranger to tell you where to go to see them.
