Is the lake open for swimming?

$3 a person is open

Yes. We were there 2 weeks ago and the lifeguards were already there. They are posted during swim times. There is a small fee (don't recall the amount) and I believe you may have to show your driver's license. You can also rent paddle boats in 30 minute increments for $4.00. Grills are available for use as well - charcoal only (bring your own).

They have a spot that you can swim

Yes

I think so. I did see the paddle boats on the water

Yes, it's open for swimming.
