We camped here in May 2019 in the tent camping area right on the river, just below the dam.   There is no electricity for the tent sites.  There is water, but not at every tent site.  Each tent site had a picnic table, fire ring and grill.  This campsite caters to RV's and it looks like several of the RV's live there year round.  There is a store.  We were the only ones camping in the tent area until our last day, we stayed 3 nights.  There is a bathroom (no shower) at one end.  Other bathrooms in the campground have showers.  We drove to the bathroom by the store and took a shower one day.  Even though we were the only tent campers, there was an extreme amount of traffic on the road.  The area had record amounts of rain and all the gates on the dam were open which had not happened in 20 years.  So, there were a lot of locals that came to see it.  We climbed Quartz Mountain on the first day.  There is not a well marked trail, you just have to try and find the path of least resistance and not die.  The view is well worth the hike (hiking shoes are a must, lots of slick rock).  You can see all the surrounding mountains, the dam, the lake, etc. from the top.  There are many hiking trails, not very many bike trails.  There is a paved bike trail, but it's not very long.  We did use our bikes to ride around the campground and up on top of the dam.  Tent sites are $10/night. If you're looking for a campground with lots of amenities, this is a good one.
