Freeze Out Lake Waterfowl Manage Area's campground it a free campground.  If you wish to camp here be prepared for more of a disperse camping experience.  While the site does have a vault toilet that is about it.  "sites" are not labeled and appear mainly to be by rows of brush.  Each site is a large flat grassy area.  A few of the spots do have picnic tables but most don't.  Fires are not allowed in the camping area.  This is a trash-in/Trash-out campground.   You will also need to bring your own water as no water is available.  If you enjoy bird watching then you are in luck, plenty can be found at the lake and ponds.  Only two others were at the campground on my visit.  Campground is next to the highway but traffic appeared light.  If the campground where to be busy and you didn't get a spot with a picnic table you could take advantage of the parking areas in the area, their are several a short distance from the campground which have plenty of picnic tables to have a meal at.
