Perris is kinda low (I guess the dam is a concern, so they lowered the water level). I haven't been there in 2 years, so I can't say whether it's shriveled up too much to enjoy...It's probably a heck of a lot closer to you than Silverwood, and less choppy until the lice chew up the water. Get there at first light, and you'll have a couple of hours of decent water.
