This is the best of several boondocking options around the Fresno Reservoir. We were the only ones here on a weeknight (right before the 4th of July). There are several choices, including some with shade under the cottonwood trees you so often find near rivers. There’s also a flat concrete pad that would work well for a big RV. You could pitch a tent here if you wanted to.
The access is good - about 2.5 miles from Hwy. 2. The dirt road is a little washboard but no big potholes.
Verizon phone service was excellent.
You’re right next to the dam outflow so not really a good place for swimming, but it looks like people like to fish here.
