Firefighters hope to have the flames under control sometime Monday night.
The fire is in the Wharton State Forest and was reported at 7:00 a.m. this morning.
It has consumed about 100 acres.
50 firefighters and 20 pieces of equipment, including two water bearing choppers have been battling the flames.
As visitors enjoyed the beach at the Atsion recreation area, helicopters have been taking water from the Atsion Lake to help douse the blaze.
The fire is in a particularly remote section of the forest in Waterford Township, just north of Chew Road and about three miles west of route 206. The area in question is mostly old cranberry bogs and heavily wooded land.
"It required us to build a bulldozed road around the perimeter to contain the fire," Michael Achey of the NJ Forest Fire Service said.
The Forest Fire Service says there have been 973 forest fires this year, burning 1,057 acres.
As of now, they do not know what sparked this fire.
