We found this spot pretty perfect for dispersed camping. The roads were well maintained and we didn't have any trouble with a FWD SUV. Recommend following the directions listed here, as Google maps tried to take us through some roads that were privately owned and gated off. We got in late which made it a little difficult to navigate but not impossible.
The spot itself is next to a pleasant stream, carpeted with pine needles and nestled among evergreens. It's remote enough that we couldn't hear any traffic or other noise pollution. It was cold in April , but very clean, beautiful and peaceful, and we wished we could have stay longer.
Perfect for an overnight stop during a long drive. The access road also serves residential property some distance away so is well maintained. The primitive camping spots are close enough to the highway to make it a quick drive but far enough away to buffer most noise from passing traffic. Even though the landscape seems sparse there was very active wildlife during our stay, with many species of birds throughout the night and a chorus of coyotes at one point. The water level was really low, which would probably inhibit launching larger water craft, but the reservoir still provided a peaceful atmosphere. There definitely isn't any nearby wood for fires so people do need to bring in their own.
