Is this campground open in December?

Open year round. Lots of sites available in winter months.

Yes, it's open, however due to flooding some sites can be closed.

It is. As someone else said, many sites are closed due to flooding during the winter. This is mostly in A and C loops, but heavy rains during a high tide cycle can close almost the entire park. Also please note - the day use area is on the south end of the lake and is not connected to the campground.

yes

Yes. Camping and Day Use is open year round. The park sits on a peat bog and is not well drained so some sites are closed during winter months.

I do believe it is...
