Officials say Delaware State Park is closed because of flooding which has made the area unsafe. State Park Authorities said they closed the park yesterday and evacuated the campground after heavy rains caused Delaware Lake to rise to 20-feet above normal. The lake was expected to crest overnight which would have potentially trapped anyone camping inside the park. The U.S. Army Corps of Engineers said they were monitoring the water at Delaware Lake Dam and would advise state authorities when the facilities were safe to reopen.
