The fire in Wharton State Forest was 100 percent contained as of Friday evening, according to the state Department of Environmental Protection.

The blaze, which burned in Camden County’s Waterford Township, near the border of Hammonton, was reported at 4 p.m. Thursday and covered 220 acres. The cause of the fire is unknown.

“We are mopping up hotspots, and that will continue until dark,” DEP spokesman Larry Ragonese said. “Then, throughout the night, we will do periodic monitoring. The fire is contained; that doesn’t mean it’s out. At 220 acres, you would anticipate that you could have some burning going on for a couple of days. People may see some smoke, or even smoldering, and they may be concerned. But even when the fire’s out, there will be smoldering for a few days.”

State Police will remain on Route 206.

Ragonese said the DEP conducted aerial surveillance Friday to get a sense of the fire.

“We found a few areas of the interior which actually have some open brush and trees that have not been touched but are inside the line,” he said. “What we’re probably going to do is a controlled burn, and burn them so that we will literally remove any fuel from the fire.”
