What a lovely, relaxing park. There is an area for day-use people, with boat rentals, a small swimming area, and playgrounds (including mini golf!). 

As for camping, you have two options: a large drive-in section (each with electric and water), some near the lake, some more forested, and some in the middle on higher ground.

Pro-tip: Site 18 has an amazing view, of the lake, and you can walk directly down and boat (but not swim) from the site. It's also on a "finger," so there's a tiny bit more solitude.

For strictly tent camping, there's a walk-in only section with a dirt path leading two two campgrounds, one of which abuts another lake. 

All campsites on both the drive-in and walk-in sections have a fire ring and picnic table. 

The camp HQ/store has good wifi and there's a weak phone signal is available in most of the park (site 18 has no Verizon signal, but walk a bit towards camp and you'll pick up two bars of LTE). I found the camp store prices to be reasonable and they have firewood bundles for $5.99. If you arrive after the office closes at 5pm, you can go to a site and check in the next morning.
