I'll start by saying that I like privacy and quiet and nature when I camp, otherwise I'd be staying in a hotel. But we were looking to get away for a weekend during the COVID times, and site 65E was the only powered site available for that weekend in all of the Wisconsin state parks, so we decided to go for it. If you're the social type with active young kids, that spot is perfect - it backs up to a large open field with cool playground equipment and has a trail to the field right next to the camper. You're also right next to the water faucet (plenty of people will stop to chat there) and across the street from the pit toilets. It's a VERY busy site. If I return, I'll pick site 107E, which is extremely private and far from everything. In general, the 100+ sites looked to be on the quiet, private side of the campground, although not all had power. Some of the unpowered sites. 69-79, had great lake views and were surprisingly spacious, although a hiking trail is between them and the lake. In late July, the loop starting with site 41 is absolutely teeming with ripe blackberries.
The shower houses have little notes on them apologizing for their state and saying they're scheduled for an overhaul soon because they're almost 50 years old. So definitely go in with low expectations. Few of the stalls for the flush toilets had working doors, and while the showers themselves worked ok, there were no hooks, shelves, or anywhere inside to place your belongings. My shower bag randomly has a suction cup and I optimistically tried to use it to stick to the pink tile wall, but even that didn't work. Such is life. Mirrors above the sinks were the polished metal type.
The pit toilets in the campsite have two stalls in each, so don't be surprised if you end up with a buddy.
The hiking trails around the park are great, nice long loops, and the ranger/park employee at the check-in area was very nice and knowledgable. We rented a kayak and paddled around the lake for a couple of hours - single and double kayaks as well as canoes are available for rent for the day. There was a rocky beach with so many signs up warning about different types of algae that we weren't sure if it was safe to swim or not, but definitely too gross to regardless. I didn't see anyone else in the water either.
If it's a clear night, the field with the playground equipment is a great place to sit and stargaze, as the park gets very dark at night. We were even able to catch a few meteors!
