Go for the scenery, not the facilities
We stayed four weeknights and had a pretty good time. The sites were loose gravel and very unlevel. Not too crowded during the week. The vault toilet was close to our site but you had to really need to use it to go in there. (Think ‘fly-tornado’ when you open the door.) We ventured out to use the shower house and found that it was a single shower for both men and women, for the entire state park! We couldn’t believe it... but more surprising was that it was a pay-to-use shower... $1 for the first four minutes and a quarter for each additional minute thereafter. Not a huge cost, granted, but we paid around $40/night for a campsite. That’s double what we’re used to paying for a much nicer campsite in our part of the world. The views around the lake were awesome. We’ll go back just for this reason. There were many trails in the park but most were poorly marked and some were simply not able to be found due to overgrowth.
