You can reserve online through Idaho power and more then likely a third party site. No power, water is available a a couple of public hosebibs. No dump site but there is one about 2 miles east at a WMA. We ussually stay on the waters edge and away for the boat launch. Be careful when booking some spots offer very little shade. Also in the summer it can get super hot and if fishing is good the dumpsters can be awful which are dont reserve any spots by them. The great part about this campground is you can stay on the shore of a great fishery and explore to small towns like Bruneau and others where you can get some worms and a ice sandwich.
