Wabamun has large group camping area's but I do not know if they are already booked.
If Pigeon lake will do then you could try

They did not mention on their website that they have camping area' s some with electrical hookups, a covered picnic area, and a very large totally enclosed covered shelter.
You do not need to be church affiliated to book the facilities in case you were wondering.
