Great for anglers!
We camped at Spicer on Labor Day weekend with our 28’ toy hauler (no OHV allowed on site). The campsites have a variety of trees/rocks and many are fairly private. We got one close to the walking trail down to the lake, which took just a couple minutes. The lake is nice but better for fishing than swimming/paddle boarding/kayaking. We did find swimming at the river leading to the lake, and it was only a short hike down. Utica is also a quick 10-15 minute drive and perfect for the activities mentioned.
The camp hosts were pleasant and helpful. The vault toilet bathrooms were clean. No reservations (except group camp, I think), hookups, or America The Beautiful pass discounts (but they do take Golden Age). There is AT&T cell service down by the lake. At the time (early September), there were a lot of bees and we saw some fresh bear poop right behind one of the sites.
