There is portable bath room, like what you see at construction site. They are cleaned.
It is a strip of land on the bank of the river. The main part of the park is the boat launch. Parking isn't plentiful. That being said, if your reveal is a small gathering, it's beautiful next to the water. There are a few picnic tables. But no bathrooms!
I wouldn't think it would be a problem
